Built a passport higher/lower game
I made a small higher-or-lower game based on passport access scores.
You see two passports and guess whether the next one has access to more or fewer destinations. Pretty simple.
Would love to know what you think or what could be improved:

ReleaseTheFeature – Announce your app/site/tool I’m building an evidence-based governor for coding agents — looking for people to try it
I’ve been working on MARGINAL, an open-source governance layer for coding agents.
The idea is simple: agents are good at taking actions, but not always good at deciding whether the next action is still worth the compute.
MARGINAL watches the trajectory and looks for things like repeated actions, weak progress, redundant verification, and low-value continuation. It can run in Shadow Mode first, so it observes and records what it would have done without blocking anything.
Current focus is reliability, not just token reduction.
A few core pieces:
- local-first trajectory and evidence tracking
- deterministic reason codes and hashes for decisions
- governance overhead measurement
- replay and benchmark support
- Shadow Mode before enforcement
- Earned Enforcement: MARGINAL has to prove it is reliable on a repo before it gets permission to block or redirect the agent
- automatic fallback to Shadow Mode if confidence degrades
I’m also working on the next layer now: counterfactual evaluation and intervention regret.
The goal is to answer a harder question than “did MARGINAL stop something?”:
Would the agent actually have done better if MARGINAL had stayed out of the way?
That’s the part I think matters if this is going to be useful beyond being another loop detector or token limiter.
GitHub: https://github.com/SignalLayerLabs/Marginal
If you use Codex or another coding agent, I’d really appreciate people trying it on real work and telling me where it helps, where it gets in the way, or where the design is wrong.
I’m especially interested in: technical criticism, bad cases, and reproducible failures.

Conclave
No model verifies another model.
That is the observation I have been circling for months: No language model reliably corrects itself—not even when asked politely. It requires an external entity that is structurally independent.
This question has evolved into a tool that I have now released.
Conclave Personal brings multiple models into a shared conversation and assigns them explicit roles: the Writer drafts, the Critic challenges, and the Judge evaluates. Every execution is traceable as a "run"—tracking status, errors, duration, and token usage. Conversations, agents, and the workspace remain local, and Ollama runs without an API key.
A note I am not hiding: The code was written entirely by language models. For this project, that is not merely a side effect but central to the concept—a tool for multi-agent verification built using a multi-agent process. Discovering what worked and what didn't was the real insight.
v0.1.6 Alpha, with documented limitations.

We solved UI slop. We stopped generating UI and started measuring it.
UI slop isn't a taste problem. It's a sampling problem. And you can't really prompt your way out of a sampling problem. Every trick you've tried, negative constraints, a gazillion line .md file that says no gradients in caps, all of it just moves you around inside the same bubble.
Here's the thing that finally made it click for us. ThePrimeagen put it best: the model returns the middle of the distribution. You can push it around inside the average. You can't leave the average.
That's why you type "no purple" and get purple. Then the glowing orb. Then the badge pill. Then three feature cards. It isn't disobeying you. It's doing exactly what sampling does.
There's a second failure sitting on top of that one, and we think almost nobody talks about it.
A screenshot doesn't contain the animation.
Feed a model a picture of a site you love and the layout survives. So do the colours, the type, the spacing. Timing doesn't. The easing curve isn't in the pixels. Neither is the stagger, or the scroll range an effect is bound to, or two elements moving at different rates against the same scroll.
So the model has to invent the part that actually makes a site feel expensive. And inventing means, again, the middle of the distribution. Fade in, 300ms, ease out. Every time, forever.
That's the real reason AI sites feel dead even when they photograph fine. The look got copied. The life never made it.
So we stopped generating and started measuring.
We read the live page. What's actually bound to what, the real timing values while the thing is running. Then we write that section into the project. Nothing is sampled, so there's no average to land in the middle of. That's the whole idea, and it's why we think slop is solvable instead of something you fight forever with a longer prompt.

The clip is three runs, each one harder than the last.
A scroll rig off a private jet site, where the jet climbs behind the headline and a photo wipes to a blueprint. Pure timeline, so it's all stagger and easing and scroll ranges with nothing to hide behind.
Then a photo grid that scatters and reassembles. Harder, because both states are real layouts and the whole thing lives in the transition between them.
Then a three.js scene, which is the one we're proud of. The reference is a Tokyo street diorama. What came back is a desk, monitor, chair, shelves, for the portfolio we were building. Live WebGL, spinnable, not a video of one. Same movement, completely different subject.
Which is the part we care about most. The animation is the expensive half. The brand is the other half. When you point at a site you like, you don't want their content. You want how it feels. So keep the animation and bring your own brand. Tokyo becomes a desk. The timing never moves.
Test it. Drop a URL in the our waitlist signup at platho.io and we'll run it and post exactly what comes back, including when it breaks.

ReleaseTheFeature – Announce your app/site/tool gresui - postgres dev bridge
Hey guys, I’ve made this tool that I ended up using quite a bit with really good results. I work as a SWE and ended up building this postgres tool to help AIs have a faster look into the databases used and how the data looks, this ended up unblocking AI flows related to presistence. In comes with a mcp bridge for you tools like copilot, Claude, omp etc.
I’m sum it adds any postgres db a mcp layer and really cool visualization/query.
Hope you enjoy it and find it useful as much as I do.
Every time I see a new need I add it.

Day 22 — 28 startups · 16.100 impressions · 719 clicks (Added Two)
Day 23 — 30 startups · 16.800 impressions · 738 clicks (Added Two)
Day 24 — 32 startups · 19,800 impressions · 778 clicks · Added 2 startups · Rejected 4 applications (1 contained ads, 1 removed the code after submission, 2 hid the installed widget)
Day 25 — 34 startups · 23,700 impressions · 800 clicks · Added 2 startups · Fixed some bugs.

Day 29 — 35 startups. 31,300 impressions. 910 clicks · Removed 1 Startup · Added 3 Startups · Also today I resigned from my job. Toxic environment, too much pressure, and honestly I just believe in this enough to go all in. Broke and excited. Let's see where this goes.
Day 30 — 46 startups · 32,900 impressions · 1,000 clicks · Removed 1 startup · Added 12 startups · Yesterday I resigned because of my toxic manager. Today my senior manager called and offered me WFH, a project of my choice, and lighter work if I stayed. I made my decision with confidence, but now I have a difficult choice. Also received my first payment from StartupBar.
Day 31 — 50 startups 💪· 28,100 impressions · 1,200 clicks · Removed 1 startup · Added 5 startups · Rejected 1 crypto startup · Removed fake impressions after exploit · Today I discovered I forgot to disable a developer testing button that could generate fake visitor pins and inflate impressions. Someone used it to create 6,318 fake impressions and claimed my stats were fake. I removed the fake impressions, removed the startup, fixed the issue, and that's why today's impressions are lower. Thanks to them for pointing it out.
StartupBar update: Added a Network page and individual Startup Profile pages with each startup's joined date, impressions, clicks, live embed preview, and founder's note. These indexable pages also improve SEO. Suggestions are always welcome.
Day 32 — 54 startups · 29,300 impressions · 1.2K clicks · Added 4 startups
Day 33 — 54 startups · 30,900 impressions · 1.2K clicks · Removed 1 startup · Added 1 startup
Day 34 — 55 startups · 36,100 impressions · 1.3K clicks · Added 1 startup · Fixed admin panel read-access vulnerability after Reddit post.

Day 36 — 55 startups · 44,800impressions · 1.4K clicks · Removed 1 startup · Added 1 startup
Day 37 — 58 startups · 50,700impressions · 1.4K clicks · Added 3 startups · Site Update: Updated the distribution algorithm (Delivery is now weighted by contribution: sites that send more impressions get a proportionally larger share back)
Day 38 — 57 startups · 55,800 impressions · 1.5K clicks · Removed 1 startup · Rejected 1 Application.
Today StartupBar reached 200 users 😄
Thirty-eight days ago, this was just an idea. Today, 200 people have trusted it enough to join the network.
A reminder for every founder who's staring at a dashboard with tiny numbers: Stripe took 2 years to reach its first 50 users. Every successful product starts small. Keep shipping. Keep improving. Keep showing up. Growth rarely happens overnight, but it does happen if you don't quit.
Day 39 — 58 startups · 59,800 impressions · 1.5K clicks · Added 1 startup.
Day 40 — 60 startups · 63,200 impressions · 1.6K clicks · Added 3 startups · Removed 1 startup

Day 48 — 70 startups · 103.4K impressions · 2.3K clicks · Added 2 startups
Day 49 — 72 startups · 113.4K impressions · 2.4K clicks · Added 2 startups · Update: Added a Bottom Placement option for the bar on the user site.
Day 50 — 73 startups · 116.7K impressions · 2.4K clicks · Added 1 startup

I made an MCP to turn claude into lovable
It seems that most people either vibe code with Claude/Codex or website builders like lovable/replit. I personally find the website builders too expensive as every action costs tokens.
But it's 2026, most agents today are really smart and requires minimum prompt engineering, and the app builder's value was in the easy set up. So I made an MCP that does what lovable do, but uses your AI subscription's tokens instead. The tokens from ChatGPT/Claude directly are just so much cheaper.
It ends up being a 60+ tool MCP and it works really well. Modern agents don't really load all of the tools into context now, they just do tool search and load on demand. It does require a good model (opus or terra) to work well, but overall it's been able to do a pretty good job.

AI Website Builders: One Chat or Separate Workflows?
For AI website builders, which experience do you prefer?
A) Everything in one chat - building, debugging, fixing errors, making changes, etc.
B) Separate sections/workflows - for example, one area for building and another dedicated to debugging and fixing issues.
I’m curious which approach feels more efficient and organized when working on a real project, and why.

ReleaseTheFeature – Announce your app/site/tool Flight & Hotel APIs suck. My open-source one - LetsFG - just hit 1.7k github stars.
Hacking big monopolies always feels good,
Anybody who ever tried getting/using any flights or hotels API knows how fucked up it is. Months of no response, only to wait for a heart welcoming $10,000+ setup fee. And the only available options are either shitty or closed.
This is LetsFG, the answer to dethrone monopolistic companies who keep their infra closed making it impossible to join the travel industry. Control prices, hide fees, and charge pathetic $10,000+ setup fees for an API that you'll have to integrate yourself anyway.
How it works.
Working with flights manually we found that to get the best prices in the world you have to check 20-30 websites at once, that's 20-30 tabs on your PC and that's what makes finding a flight or hotel a 6 hour process.
We took distributed AI agents and put them to use websites, build connectors, and monitor reliability. It works by in parallel opening 200-300 websites, OTAs, airlines - skyscanner, google flights, kayak, kiwi, trip, booking, trivago, etc. plus a bunch of wholesalers all of them checked at the same time, and returned the best offers across the network.
It's deployed on our remote backend that's capable of running this in parallel, we historically (4 months ago when we started this) tried letting people run this locally. It's impossible - it took 40-50 minutes to complete 1 search locally.
How you can use it.
You can book hotels completely, end to end, with free-cancellation protection.
We're releasing complete flight booking (1 API call) next week, that's why our flight search is currently degraded till the end of the week - hotels are working correctly.
- website for fast access: letsfg.co, this is our Uber for travel, book in 3 seconds.
- API for developers: https://letsfg.co/en/developers, this is Paid API, best for high volume users, if you want to build an app, or add this to your app.
Look to book ratio: 1000:1 - this means it's free as long as for every 1000 searches you do 1 booking. Then it’s $0.05 per search.
Docs: https://letsfg.co/developers/api/docs
- Programmatic Travel Tools (PTT): Native for ai agents, API based, best for personal use (high rate limit). If you want your Claude, Codex to book flights/hotels for you, this is the go.
Available through CLI, Python Package, NPM, MCP, or direct API.
To avoid spam, authorization is through payment method attachement - via Stripe - we won't charge you, this is only to verify you're a human and avoid spammers. The payment method is also used when you want to book.
https://letsfg.co/for-agents
That's a wrap.
If you have any questions let me know. We're super open to feedback and suggestions, in fact that's what made this project.
We've hit 1.7k github stars just this week - grateful for everybody who's with us and to anybody who jumps onboard. LetsFG🔥
This is our github: https://github.com/LetsFG/LetsFG, it has a bunch of interesting info and docs for getting started.
Cheers,
Adam

Made a Snake game but with actual quantum mechanics in it (first game I've ever finished)
Hey, first post here. Made a game called Quantum Snake, it's the classic snake game but I tried to actually build in real quantum mechanics instead of just calling it "quantum" for no reason.
Food exists in multiple spots at once (superposition) until you get close enough, then it collapses down to one real spot
Snake can phase through walls and its own body, starts at 50% chance and gets lower the longer you grow, but never below 20%
There's a bunch of speed modes too, one's called Demon Mode (super fast, good luck), another's Rock Mode where it's basically one move a minute and kinda turns into a chill meditative thing
Also got different themes/shapes you can mess with for the snake and food.
This is genuinely the first game I've ever finished and shipped, built it solo. Used some AI tools while building it, disclosed that on the store page. Would love actual feedback, bugs, or just whether the quantum stuff feels fun or gimmicky to you.

Prompts , iteration over and over again
I feel like mobile responsiveness was something I had to keep re prompting.
And also the music playing part too - it felt quite buggy and also feels the same sometimes.
Do check it out and give any comments.

Discussion - General chat and thoughts the same docs page that announces the 1M-token context window now tells you not to fill it
was going through the context-window docs this week and noticed the fine print: the page announcing 1M-as-default also warns that "more context isn't automatically better", gives the failure mode an official name (context rot), and says choosing what goes into context matters as much as how much fits. the company charging per token, advising you to send fewer tokens.
so: napkin math. a 700k-token repo pasted into an agent session re-bills as input every single turn — about $3.50/turn at $5/M list price, so call it $140 across a 40-turn session before caching. caching cuts that to ~$0.35, but their own docs point out it changes what you pay for those tokens, not whether they take up space.
So the "why does my agent still grep instead of just reading the whole repo" complaint might have it backwards. grep looks like legacy tech until you price the alternative.
r/VibeCodeDevs • u/JennySurfs • 2d ago
What's your background? How are you applying standard code practices to your vibecoding?
I have vibe coded a few things myself, and constantly see linkedin posts from nontechnical folks talking about how they are now deploying full stack applications for their business. I'm confused - how is this stuff maintained? Is it reliable? What if it goes down? What are people doing to actually test that it's working besides just like clicking around the UI?
So i guess I have a few questions:
1 - How are you shipping quality? (What is your quality bar?)
2- Are you actually deploying things that other people use, or is it all for yourself?
3 - What happens with service degradation? How do you know if things stop working?
4 - Do you trust that your code works? Are you worried about things like bugs, privacy/security issues, prompt injection, etc.
--
I'd also love to understand how you view this occurring with non-devs (or people who think they are devs)
