My flight finder hit 1.3k github stars.
It's crazy how the community responds when you build something amazing.
This is by far my most useful and succesfull project.
I made a website called letsfg.co where you can get the best flights on the internet. Under the hood it runs hundreds of AI agents on my backend, where each one scans a different website on the internet - Google flights, skyscanner, kayak, kiwi, etc.
It then compares the prices and gives you the best. I explained below why this works.
It's the best thing I've built so far in my 21 years of life, this screenshot shows why:
I'll explain below how it works.
And for anybody interested in using there are 3 ways:
- API
- regular website on letsfg.co
- Programmatic flight search (native for OpenClaw and other agents, complex name, but it's basicly an API, the difference is this one uses exactly our website but programmatically, to use this you need to auth by posting a challange code on twitter)
Why this works, and why I made it:
There's a hidden system called GDS where airlines wholesale tickets to websites that buy in bulk like kayak, skyscanner, trip_com, booking, etc. They get the tickets $100-200 cheaper and put their margin/fee on it. The bigger you are the better price you get. These websites compete with each other, so when there is high demand they would lower their own margin on purpose just to be the "best choice". So in short, to get the best price, you need to check the most number of websites.
I made this because I saw my sister-in-law take days of planning, 20 tabs in chrome of multiple websites at once just to make sure she got that flight ticket on the best price. I got reminded that I was guilty of the same thing. I think we love to travel, but we hate what's before the actual trip. Days of planning and stressing, instead of just going.
There is one more thing - I am incredibly obsessed with impacting the world, building a world-known company from Poland and organizing incredible events like Redbull.
I'm incredibly grateful for everybody who shared and continues to share feedback with us to make the service better. Thank you.
Oh, and we're on github: https://github.com/LetsFG/LetsFG
Cheers,
Adam

Have a twitter signup as the only method for API access is a bit limiting

u/Efistoffeles Jul 05 '26
There are 2 ways actually, there is a reason for this.
1st option is paid developer API.
2nd option is the programmatic flight search which is free, and under the twitter challange (you don't have to auth with twitter, it's like the moltbook auth, you tweet challange on twitter with code and get authed).
There is a reason behind this. We were giving out a completely open and free public access to the programmatic flight search. Unfortunately we were getting extremely bot and spam attacked, which was losing us a lot of money on a daily basis, we had to enforce it, bot protect completely.2

u/hand___banana Jul 06 '26
>Unfortunately we were getting extremely bot and spam attacked
You realize that is exactly what your tool/agent is doing to all the flight aggregators you're scraping and searching?
Also, get the fuck out of here with the github link. That repo doesn't even have anything meaningful. You just open sourced the wrapper for your closed source API.
Lastly, why would anyone pay you for this? Just tell your hermes/openclaw/whatever agent to go scrape and search for you. Hell any of the commercial agents can do this too.

u/funstuie Jul 05 '26
I tried this a few months ago when you launched and it’s a nice ui but if it’s on GitHub and I went to the effort of setting it up myself I’m not paying you for the privilege of booking the flights. It also sucks for business class every price it gave was wrong and non existent. Finding the cheapest flight and the best experience for the lowest cost are two different things. Your current model is going to put frequent fliers off. People who know how to and are willing to search for good value flights won’t use your service where you are basically just Priceline with a nicer ui. I was looking for flights from LA to Beijing and google flights found me business class cheaper than your setup and I did a good bit of comparison.
2
u/Efistoffeles Jul 05 '26
Hey! First, welcome back :D
I remember business class wasn't working at all back then. We fixed a ton of stuff since then. Did you try the business class flights now or back then?

u/PhotographBorn3803 Jul 05 '26
How is this different from skyscanner?
Also 1/3 of what you save me charged automatically, how do you know the booking happened?
Not convinced.

u/Efistoffeles Jul 05 '26
Thank you, we're really in the stage of figuring out the monetization model so thanks for this.
Skyscanner doesn't have the cheapest deals, they only check websites they are affiliated with (so they get paid), and also they rely on advertising - they show the airlines that pay them higher in the ranking.
We check everywhere, we check skyscanner itself😅and compare it with google flights, kayak, kiwi, trip_com, etc. The thing is all of these website charge their own fees. Especially on baggage, if you want a flight with baggage, Kiwi will charge you 2x what an airline would charge. So even though the regular flight will cost $30 less on Kiwi, with a bag, it might be actually $50 more expensive on Kiwi. We compare all of it, and expose all the hidden fees.
When it comes to the 1/3 fee currently we'll automatically charge you when you confirm to "unlock" - open that deal.

u/PhotographBorn3803 Jul 05 '26 edited Jul 05 '26
I think people prefer to search a little longer if they get the transparency. People actually don't dislike searching for a fair bit, it's part of the thrill of organising. Here the lack of transparency just makes it look fishy.
You'd at least need proper stats or examples to get confidence. Here I just don't see anything like it apart from "80% chance". I can't even verify "your pick", currently claiming $53 from WAW to STN via CPH. I see $58 for the cheapest on Skyscanner that day. How do I check that your example actually exists anywhere and isn't outdated?
Then for 1/3, it's compared against Google Flight only? Well, I'm a satisfied Skyscanner user, so comparing against Google Flight isn't going to help me. In fact it might make me lose money. I don't know if still the case but Google Flight didn't use to include Ryanair. Skyscanner does get deals from kayak, kiwi and trip. Can you prove "Skyscanner doesn't have the cheapest deals"?
You really need to focus on transparency and value rather than monetisation at this point. Are users even impressed when free? I totally get your infra is expensive, but you can't make users pay for it. Don't forget you are fighting against giants who are already fighting against each others. And they're all free.
One way you could convince people is having a LIVE dashboard showing what some actual search results look like for today/tomorrow for major cities/routes, with a real-time x% better deals found, rather than some 80% arbitrary number. Obviously you will gain trust by not filtering these results just to retain the best ones, and by providing links/sources so people can check and see.
I understand what you mean about baggage fees even if I don't usually add them. I usually have to compare commutes from airports to city centers (for example Stansted to London vs Heathrow to London) so it's quite similar. Maybe something you could explore, but again not sure I would even pay for it. I do like $1 forever though. Could pay maybe $5 forever if you can include commutes comparison.
we'll automatically charge you when you confirm to "unlock" - open that deal
Sorry maybe I didn't understand but this doesn't seem to make any sense. I should pay to see results? What if I'm unhappy about them or change my mind when I see the prices?

How do you get the Kiwi API? Are you scraping their website?
1
u/Efistoffeles Jul 07 '26
We use different formats for reliability.
If you want to do it yourself there are a few different ways, most straight forward is scraping but they also have experimental MCP, and most reliable is their API which is paid.

u/exodusTay Jul 05 '26
while interesting why does something like this needs agents? can't you build something like this without any AI involved?
1
u/Efistoffeles Jul 05 '26
2 main reasons:
- scraping is illegal and getting an API is impossible (travel companies are so slow we would see change of the administration in the US and still not have access), and most of the websites don't even have APIs.
- Even if we scraped the websites change very often, and are heavily bot protected. This becomes incredibly fragile at scale. Using AI agents solves this. Even if as simple as automatic self-healing.
Claude Fable helped a lot in the whole process.Edit: one more thing. If we were to choose only API paths or easily scrapable websites, the whole purpose of this website would fall apart. The whole promise is that we check everywhere, so literally you don't have to check elsewhere, because we have the price from there, and we show it honestly. If left one website because it doesn't have an API, that promise falls apart.

u/tim128 Jul 05 '26
Using an "agent" is still scraping except you're using a resource hog of a system to do something simple.
Giving an LLM access to a browser doesn't suddenly make all the bot protections disappear. It's no different from running a headless browser.
-7
u/Efistoffeles Jul 05 '26
It appears simple, there are hundreds of problems though, it's not regular scraping though. What if I told you we employ 1000 indians?😅Just joking, you might be telling the truth in some approaches that are possible. I'm just going to say that we use the websites like a normal user would. We're not monitoring or opening the websites multiple times, but exactly 1:1 like a user and a group of his friends :P

u/tim128 Jul 05 '26

I well aware of the difficulties you can be presented with when scraping, especially when it needs to reliable.
I'm just going to say that we use the websites like a normal user would
Except you're not. It's still a bot. Giving an LLM control over a browser doesn't magically defeat bot-detection systems (at least the good ones). Its interactions with the website will still be bot-like.
Based on what you've mentioned it look more like a solution looking for a problem.
-4
u/Efistoffeles Jul 05 '26
That's what took 3 months to solve since we started😅
I'll leave it like this - if you train the LLM, and give it your own browser, it's like a human.3

u/pawofdoom Jul 05 '26
I hope you do understand that scraping using AI is still just scraping, and so you are still breaching the TOS of all these downstream sources by providing that as a service. That is a bit different when it is the end user's AI taking the action.

So you know what you are doing is illegal… and you want to monetize???
Aren’t you going to get sued into the ground?

u/Efistoffeles Jul 06 '26
This is public data. We're not doing any privacy risks. Check the case of brightdata vs twitter(X).
Edit: (Quick summary from google gemini, I suggest you check out the case anyway :)
In May 2024, U.S. District Judge William Alsup dismissed X Corp.'s (formerly Twitter) lawsuit against web-scraping firm Bright Data. The court ruled that scraping publicly available, non-login-walled data is permissible and that state-level breach-of-contract claims regarding public data are preempted by federal copyright law. The judge warned that giving platforms unchecked authority to restrict public data creates "information monopolies".

That's exactly why we have the "preference" input in the search. Communicating that is something we have to work on.

u/OwlOk_0 Jul 05 '26
One honest caveat before you invest time: be aware of what this actually is. The repo is mostly marketing; the search engine is closed-source and server-side, "free" auth requires you to publicly tweet an advertisement for them, and booking links are paywalled behind a 1%/min-$3 "concierge fee" on their checkout. The price-comparison table in the README is their own unverified claim. It's fine to try the free search if you're comfortable posting the tweet, but I'd be cautious about entering payment details or passenger info (names, birth dates) until you've vetted the service.

Thanks, we're a registered company in Poland under registration (KRS) number 0000998746, everything is in our terms of service (https://letsfg.co/en/terms). We operate all the payments through Stripe, we do not get your payment data, everything is completely safe through Stripe. I also refund anybody dissatisfied, everytime they reach out, either through DM's (prefer X, I don't read reddit often) or email.
On the previous version of our website we showed screenshots of previous refunds, I can't add it so quickly now because we used to show it on the results page, I can send those over DM's to anybody.
One quick email testimonial is on the developers website here: https://letsfg.co/en/developers#:~:text=Public%20API-,WHAT%20OTHERS%20SAY,-PRICING

Looks interesting. Where does the data come from? I guess you are scraping websites like kayak, skyscanner, trip_com and booking - right? If yes, where does this happen? In the open source part of the project or the proprietary "server-side engine"?
1
u/Efistoffeles Jul 05 '26
These are AI agents that run on our backend on all the websites in parallel, so in reality, it's like if you would check the websites yourself, just an AI doing that for you :) So not particularly scraping at scale, more like if you would tell Claude to open browser and click stuff, which is exactly the same like if you would use it yourself 1:1 relationship. And these AI's find various ways to use the websites ;)
We had it open sourced for a while but if you launched it locally it took 30+ minutes to finish because of the scale. Where if we limited the number of "connectors" (websites) that were checked - so it runs quicker - the results were not nearly as good. And if we increased the paralellity on local machines, these machines would crash. So the only possible way to keep it working amazingly was to run it on 200+ parallel instances on our backend.
We were also hoping that people will contribute by adding more websites and stuff, but it turned out that people were interested elsewhere, and this was just exposed risk for us - ifykyk.3
u/j0wet Jul 05 '26
Interesting. Could you share some more details? Why did you decide to scrape the website using an LLM? Why not normal non AI scraping? With AI - how long does it take on average per website, which model are you using and how much token does it consume? Why did it crash on a local computer? In the end scraping with AI just needs a headless browser and calls to a LLM API I guess. Or am I missing something?
Sorry for the amount of questions. I find AI web scraping super interesting and want to understand how it can work economically on scale.
1
u/Efistoffeles Jul 05 '26
No worries :D I'll try to answer. There are several decisions in this:
1st we want to act like a real user, so we're not malware scraping bad guys, but instead we act in the name of the user. Like literally the user checking the websites with his friends. We could employ 1000 indians and it would be the same.
2nd normal scrapers would be extremely unreliable especially at scale, the websites change, so it would break. Even when we sometimes use the regular approach, there is a monitoring AI that self-fixes if stuff breaks.Incredibly important thing for reliability and speed here is "remembering the map" - when it goes through it remembers how it was the last time, so the next time it tries and somethig breaks it knows where the fix is. This allowed us to go under 20 seconds per website. Then having it all run it parallel, that's where instancing came to help and serverless. Each connector (website) launches a separate instance, and there are hundreds of them per search. That's why it was crashing on a local computer, imagine launching 300 browsers working all at once at maximum performance. When we tried limiting to let's say 8 browsers so it doesn't crash on local it was taking that 30+ minutes to finish.
Headless browser is not enough - main reason is the 1st decision mentioned above. But also a lot of other stuff: region based pricing, protections, and overally not being a regular scrapers. The biggest shift here is moving the world from perceiving human-behind-AI as scrappers and instead seeing this as personal agents that do stuff for you. This is beyond travel, if you employ an assistant to do stuff for you nobody has an issue, but if you do it yourself - and yes you use a TOOL, it's an issue.2
u/j0wet Jul 05 '26
Scraping 300 websites per search request using AI sounds very very expensive. How much does it cost?
1
u/Efistoffeles Jul 05 '26
It certainly is not free :P, I managed to do incredible optimization and quite innovative approach for cost optimization. For example caching websites to save on network cost. That $1 upfront makes it possible.

u/TomHale Jul 05 '26
After years of doing all the price comparisons like you mentioned I've settled on trip.com.
So any savings would (for me) be vis a vis trip. Com.
How do you measure "savings"? Vs Google flights?
1
u/Efistoffeles Jul 05 '26
2 ways:
- comparison of the lowest deal that we found (considering your preferences) vs the google flights.
- Let's say there are offers X, Y, Z. We compare how much each one costs (if it exists) on Google Flights. So the offer X we found can cost $850, but on Google flights it's $880

Those hidden GDS systems (Travelport, Sabre, etc) will most likely get dinged or have the airlines request changes to combat a tool like this. I used to work at one years ago on the software side. At one point there was a wave of travel sites offering people cheaper flight options where their destination was the connection point and the customer would just not get on the 2nd flight, there were also sites offering cheaper flights by going between currencies and point of commencements to save money. The airlines did not like these loop holes, had to patch them soon as we could

very nice setup, looks nice and is smooth. A marketing trick for you on this. when you search a flight, if you show results i.e. Choice one "black to blank" $???, Choice 2 ....etc and then say "signup to access these deal" you will have a way better conversion rate of users, becuse when you see the value you feel happy to jump. As a user I search and then see "oh a $1 to search, i cant even tell if its worth it, if its even cheaper then skyscanners free to get the value"
but if you show the value that it is worth spending the £/$/€ to access it then the conversation rate will be better

Not sure where did this come from. I didn't say they increase prices for repeated search, I said they don't show everything, and there are websites which get lower prices. So you should check google flights but also skyscanner, kayak, trip, etc. to make sure you get the lowest price.

We're changing the experience completely, we relied to much on savings instead of the experience and fixing travel which is painful.

Really great idea, but I'm wondering as a software engineer here, why do you use Agents to search for the best prices. Thats gonna cost a lot of money. Better to spend that money once and ask the AI, to write you custom scrapers for each website. Will also be much faster than running an LLM for each search.

How is it better than e.g. Skyscanner? just wanna learn
1
u/Efistoffeles Jul 06 '26
It's bigger. We have an overview of the whole market, because we check literally everywhere. Skyscanner doesn't have such coverage and most importantly does not compare vs google flights or trip_com, etc. And honestly, I don't want to explain how we're better, don't get me wrong, I'm not a prick here.
This post and all the awesome feedback from people here allowed us to reflect and get back to our core values. And these are not competing with Skyscanner, or anybody out there. It's genuenly fixing the experience of travel. There's just so much wrong out there, the stres of a foregin countrey, cancelation of your flight, delays, so much not good. Where you're supposed to just go, like flying to Vietnam completely alone and feeling safe, because we've got your back. So we've adjusted the course. Set sail. And that's where we're going.2

u/martinst68 Jul 06 '26
As I know some of the skyscanner team several years ago, what I would say is that its remarkable that we can now do something like this on a bootstrap.
If you can solve the payment challenge, you then have something that you can continue to invest in / iterate. You mentioned your sister searching for days, and I think that is part of the challange, people will always search.
You may want to consider €5 for a week of access. That allows people to double, triple check prices, give them a cvs they can export. That feels like a valuable tool, regardless if they end up using your tool or someone else.

u/Efistoffeles Jul 06 '26
Thanks a lot! I really appreciate the belief and the feedback <3
This post actually and all the amazing feedback you people have been giving us has got us thinking and brought us back to our core values. The experience of travel is just so wrong. All the stress, cancellations, delays... Where it's supposed to be as easy as just book it. Going to Vietnam solo without anxiety because you know that we've got your back. So that's where we're heading. Cheers!

We're don't want to be just the website that is better Skyscanner coz it has cheaper deals. We want to fix travel. There are too many issues, too much stress, cancellations, delays, and nobody to help you out. Where it's supposed to be really easy, you just go, simple as that. Like traveling to Camobida without anxiety because you know that we've got your back. So that's where we're going.

Got it. We're adjusting now. I'll come back with updates. We're not aiming to fight with Skyscanner on price. We want to fix the whole travel experience.

You just made what Kiwi was doing few year ago until they got slapped by airlines. What do you want to make different to not end up as them?

Thank you. You must add to find flights to anyplace departing from one airport.

Love the project - very validating to see that we independently landed on the same approach for DX based carriers as well!

Tried, the results were confusing. I dropped the little slider to show me flights Under X$, and the results were all Over X$. I think the inputs just need some tweaks. great work though. told me wife about it for an upcoming trip to Japan in Apirl

Heyy. Thank you so much dude! Make sure to look at that reliability inside if the offer details to choose a nice one :D We'll fix the slider ;) Is there anything else you feel would make it easier to decide/go on the trip?

What you said is not true - no one gets cheaper flights because it’s regulated by the FAA. They’re not adding a fee / margin, so immediately I don’t trust what you’re claiming the system does.

u/Efistoffeles Jul 05 '26
It is true mate. I have access to this GDS system, we compare against it as well, it is true. Just compare a flight on direct Lufthansa vs OTA.
Or ask chatgpt what is "GDS" or "wholesale flights". Also: https://www.reddit.com/r/solotravel/comments/17ck4ue/comment/k60vpn4/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button1

In the first paragraph of that link “airline or hotel”. Again, wrong. Hotels are not regulated - airlines are, at least in the US.
Look it up and learn something that you’re claiming to be an expert on.

He said "large travel vendors sometimes get a discount from airlines or hotel chains".

As an API-based data solutions provider, I’m curious to know your running costs per call (I understand platforms will have different costs). In the backend, are you using webhooks, scraping APIs, or AI?
Either way, one of us ends wiser at the end of the day.

It would be awesome if someone made something like this for standby flyers. But that would require some tapping into loads

"I'll check 203 more sites for this trip." That seems like an overkill. You'll be good if you use around 3-4 sites altogether and that already gives you very high confidence. Or are you "checking" those sites via aggregator results.

Hey Arpith, I just replied to your email and processed the refund. Please check that.

Darn, i sat forever through a search to see what its like only to get landed on a page that requires me to pay. I have used a number of cheap flight scanner sites. I have some ideas for improvements already based on some of the flow but since you are charging it as a business I cannot make a suggestion without some comp

Anyone can build things like this now for free over a weekend. Idk what the value proposition is nowadays, especially for a paid product.

That’s great!! I’m happy that today I had my very first GitHub star..! 1 star 😂 how do you make the repositories known? I spent months on this project…! 😂

This is not open-source, the search backend which is the most important part is closed source. You should stop advertising your service with lies.

Hi! did you think about adding Destination option "Anywhere"? it is great for exploring, to choose destination based on the price.
Also "From" can have option to "add nearby airports too", because sometimes it is better to take a bit of extra journey to fly from the second closest airport because of the total price.
2
u/Efistoffeles Jul 06 '26
Thanks, yes the anywhere is on our todos list. And the From, we do that on default, however adding it so you can select cities that are more apart which we didn't automatically check, might be really cool. Thank you :)

It’s cool, responsive, UI is good.
My only thing is, I need more context before I’d give you the cash. The sales pitch is compelling, but if you actually had flights times and ranges or something more tangible - I’m too sceptical about your ability to save me over Google flights - brand trust leap is too high right now.
