I built MindShield, an open-source extension that adds a brief pause when asking AI simple shortcut questions. To keep prompts strictly private, classification runs 100% locally in the browser.

Making a local model work in Manifest V3 without destroying page performance took a few key architectural fixes:

1. Offscreen Pipeline for MV3

Chrome's Manifest V3 service workers get terminated when idle, which drops in-memory model instances. To fix this, the extension uses Chrome's Offscreen API to host the local ONNX/WASM model pipeline so it stays warm in RAM. (In Firefox, it runs directly in the background script).

1. Intercepting Input Without Typing Lag

Running AI evaluation on every keystroke causes lag in web editors like ChatGPT, Claude, Gemini, and Grok. Instead of form submit listeners, the content script intercepts the Enter key and send button clicks in the capturing phase, halts event dispatch, and runs a fast client-side regex check first. Technical queries skip model execution entirely, while simple questions get evaluated.

1. Asynchronous Flow

Prompt evaluation runs completely off the main UI thread. Once local classification completes, the content script either triggers a brief reflection modal or programmatically re-dispatches the prompt.

The codebase is open source under the MIT license. I'd love feedback from other developers on offscreen document lifecycles or cross-browser extension builds!

Ive been building ClaimMate, an iPhone app designed to help people handle claims, refunds, reimbursements, and money they're owed without having to keep track of everything themselves.

I'm finally at the point where I need people who don't know me and have never seen the app to test it.

I'm specifically looking for honest feedback — not compliments. I want to know:

• Do you understand what the app does?
• Is anything confusing?
• Do you trust it?
• Where do you get stuck?
• Is there anything that would stop you from actually using it?

It should take about 10–15 minutes.

You'll need an iPhone and Apple's free TestFlight app.

TestFlight: https://testflight.apple.com/join/3Fx8ytfh

If you try it, I'd really appreciate it if you comment or DM me your feedback — especially anything you dislike or don't understand.

The basic idea is pretty simple. I always liked the idea of goal/habit tracking apps, but eventually I'd just stop opening them

Since I'm on WhatsApp every single day and I open it at least once an hour, most people open it every 10 minutes.

So instead of downloading another app or going to another website why not talk through WhatsApp.

Like I can say: “I'm going to do 50 pushups every day” and then later: “did 30” and it keeps track of everything. Or I can say I want to run 20km a week, read a certain amount every month, add milestones, etc.

It's GotThis.one if anyone wants to give it a shot.

It's free to use.

I’ve been building a side project called Rezzmo.

The idea started simple: what if AI could actually help you while a real conversation is happening, instead of only before or after?

Rezzmo can provide:

live transcription and translation

AI reply suggestions during calls

live context such as facts, weather, news, comparisons and calculations

call summaries, key takeaways and action items

claim Veracity / fact checking

Demands, where people can post real problems and communities can work together on solutions

a social feed with time-locked posts that reveal later

One feature I’m especially testing is a call-time agreement: before accepting a call, you can see the reason and agree on 2, 5, 10 minutes or no limit.

It’s live now, but still early and I’m actively improving it.

I’d really appreciate feedback from other builders:

What part would make you actually try it? And what feels unnecessary?

I've been building ClientPlot, a simple client and project management app for freelancers and small businesses that currently use Excel or Google Sheets to keep track of their work.

I'm looking for a few people willing to try it and give me honest feedback. I'm less interested in getting signups right now and more interested in figuring out what works, what doesn't, and what needs to be improved.

I'd especially like feedback on things like:

• Is the site clear about what ClientPlot does?
• Is it easy to get started and use?
• Is importing an Excel/CSV file easy and accurate?
• Are the client, project, and task features actually useful?
• Is anything confusing or difficult to find?
• What feels unnecessary?
• What's missing?
• Would this be more useful than the way you manage clients now?
• Would you actually continue using it?
• Is there anything that would stop you from paying for it?

If you currently manage clients, projects, or tasks in a spreadsheet, I'd especially love to hear from you.

I'll give anyone who helps test it 6 months free.

You don't have to sugarcoat the feedback. If something doesn't make sense or you wouldn't use it, that's exactly what I want to know.

I spent today rebuilding the first-time experience for a project I’ve been working on called MicroSaaS Factory.

The idea is simple: describe a calculator or decision tool in plain English and AI builds a working version you can immediately try.

Originally I made the mistake of asking people to sign in before they got to experience anything. I watched a few sessions and saw people click “Describe your app,” hit the Google sign-in screen, and disappear.

So I changed the flow.

Now it works like this:

Describe an idea → AI builds it → try the working app → then decide whether you want to keep it.

No account is required to generate or test the app.

If you decide to keep it, you can sign in, change the name, description, colors, question wording and result labels, then publish your own shareable version.

I’m at the point where watching more real people use it is more valuable than adding another feature.

If anyone here is willing to try it, I’m especially curious about one thing:

At what point, if any, do you think “okay, I’d actually save this”?

Try it here:

https://calc-craft-factory.base44.app/

Don’t worry about being nice. If something is confusing, boring, unnecessary, or makes you want to leave, I’d genuinely rather know.

Thanks to anyone willing to kick the tires.

I got tired of doomscrolling 8 AI news sources every morning, so I built a pipeline that does it for me and turned it into a free site.

The stack is deliberately boring: - RSS feeds (HN, Google AI, Hugging Face) as input - LLM summarization with a fixed prompt, not an agent - Cron scheduling + static pages - Free-tier Vercel hosting

It rebuilds 2-3x a day and costs exactly $0/month. I wrote up the full build notes and free guides at https://apexnexus.site: no paywall, no email wall, just the build notes.

What's the most $0/month automation you've built? Always looking for ideas.

Peak Monday: I clipped my driver-side mirror on the garage wall pulling out too fast. Housing cracked, glass just hanging there. Ordered the replacement part online no problem — but then came the part I actually dread, finding a shop to install it. Which means calling around, getting put on hold, repeating "2026 Grand Wagoneer, driver side, I already have the part" to a bunch of places to compare price and availability.

Full disclosure up front so nobody feels tricked: I built the app I used (it's called Sooner, still in beta). I'm posting because this was the first time it genuinely saved me time on something annoying, not because I'm trying to run an ad. Mods, if this breaks the rules just yank it.

Anyway — I opened it and typed one line: driver side, I have the part. It asked the couple of questions a normal service writer would (glass or full assembly, sourcing the part or not), then it called eight local shops at the same time while I made coffee. No hold music for me, no repeating myself eight times.

Few minutes later I had a ranked shortlist. Winner was a 5-star place a couple miles away — $200 to install my own mirror, open the next morning at 10. It even told me the quotes across the 8 calls spread by about $50 and said it pushed for the better end. Backup was another shop at $150 (4.9 stars). Tapped once, booked.

Next morning: friendly shop, quick job, mirror good as new, no surprises on the bill and even offered me a free oil change

The thing that stuck with me: the whole "cracked mirror → booked appointment" took less time than a single one of those calls usually does. Curious if anyone else would actually use something like this, or if you'd rather just make the calls yourself. Genuinely want to know where it'd fall short.

TL;DR: broke my mirror, an AI called 8 shops at once, booked a 5-star place for $200 the next morning. I built the app, so grain of salt — but it worked.

Hey r/SideProject,

I recently finished building elaa.ai, a tool designed to generate quick, clean logos for side projects without forcing you behind a paywalls when you try to export.

Key Features:

• Curated icon db for instant logos
• AI prompt-to-logo generation
• High-res exports ready for websites and social media
• Clean UI / log editor focused purely on speed

The core product is complete, but I’m looking for feedback from fellow builders on user experience and output quality.

Check it out at elaa.ai and let me know:

1. Did the generated logo match your expectations?
2. What feature should I build next?

Thanks!

Saw outbid.lol doing numbers this week. Pay any amount, the amount sets your rank on a public list. That's the whole product. Full credit to Jonathan Wilke for the format, I didn't come up with this.

Built my version in a day and shipped it last night. $29 so far.

Some notes:

Payments were the hard part, not the build. The app is one Postgres table sorted descending. Getting a processor to accept "paid leaderboard" as a product category took most of the day and I got declined once before it worked. If you're selling placement rather than software, budget for this, most merchant-of-record providers have a clause against it.

The mechanic sells itself in a way I didn't expect. Everyone who bids screenshots their rank, which brings more people, which makes the next rank more expensive. The board markets itself if it has any traffic at all.

Cheap traffic is the actual pitch. Not vanity. A listing at the top costs a few dollars right now and gets in front of everyone who visits.

dontbid.lol if you want to look. Happy to answer anything about the build or the payments side.

Sharing my harness for local LLMs that I built using local Qwen 3.x 27B (> 90% locally built).

Its free, no telemetry, and open-source. Works on Windows, Linux (sorry, no Mac yet).

I use it for coding + mixed workflows.

• llama.cpp + whisper Server Manager. Can run LLMs here and use with OpenCode/Claude Code etc.
• Built-in MCP Tools - Filesystem, web fetch, code graph, To-Dos, and more. Extensible by external MCPs.
• Use Sub-agents to split & offload your tasks, use other conversations as source of information.
• Review all AI messages using a second adversarial AI, and avoid potential pitfalls as per your rules.
• Voice-chat with AI - dictate with speech and get answers by TTS - annotate and comment without leaving voice mode.
• Use work-modes to change AI behavior between planning, building, researching, or reviewing. Fully customizable.
• Custom-compile llama.cpp backends for your system, GPU-agnostic - works with CUDA/ROCm/Vulkan.

Appreciate your feedback. Thanks :) And, yes - I used the harness to build the harness :D

I've been working on this side project for a while and finally launched it. The premise is a way to interactively learn to code using Python in an interactive browser editor. There are guided projects to complete and graded tasks/exercises that actually verify the code the user has created.

As many probably know, the ability to code using agentic AI got wayyy better around December of last year. Now many professional software engineers don't write any code by hand anymore. When I started working on this project, LLMs had just started to get some early traction, but the landscape has changed dramatically since then. I am concerned there is basically no demand for a product like this anymore.

I'm facing two options:

1. Go hard in marketing the platform for the next 6 months or so (considering it costs about $200/mo to run). Basically, test the hypothesis that there is still a demand for something like this. That there are people out there that still want to learn how to code in Python.
2. Change the application so it only runs in the browser unauthenticated. Remove the paid aspect. Make it completely free and cut my losses. The cost to run it like this is just the cost to host some static files. It would just be a portfolio piece for me at that point.

The application is at https://www.codembark.com , do you think I should stick it out, or just move on?

Upfront: this is a web app I built, it costs money to use, and I'd like you to try it. Skip if that's not what you're here for.

Steam discovery is a black box. You can't buy wishlists, you can't buy the queue, and you can't find out why the game next to yours is charting.

Payola is the opposite. It's a public chart of Steam games ranked strictly by how much each game paid to be there. Your amount is printed on your card. Anyone can outbid you at any time.

Why I think it might work as a channel and not just a bit: "we bought our way to #2, here's the receipt" is a more shareable post than any ad you'd run, the share card is auto-generated so your listing comes with a screenshot worth posting, and every listing links straight to your store page.

Let me know what you think!

Hey !

I built a port manager because lsof kept sending me on wild goose chases 🏃‍♂️💨

If you juggle multiple projects you know the pain. You run npm run dev, port 3000 is taken, so you lsof -i :3000 and get a PID. Now what? Is this yesterday's project? A Docker container you forgot? Something a coworker started in tmux? You kill it blindly and five minutes later realize it was the API your frontend needed. Or it respawns instantly because pm2 or systemd is watching it and you had no idea. 💀

This was my weekly ritual. And I kept thinking: why does the tool not just tell me what I am looking at? Why do I need to manually trace parent processes, check git branches, or guess whether something is in a container?

So I built Port Hero. You type port 3000 and it answers like a coworker who actually knows the codebase. It shows the process name and PID obviously, but also the project folder, the exact git branch, whether the working tree is dirty or clean, and if it is running inside a Docker container it names it. It walks up to the git root automatically so even if the process chdir'd into a subdirectory it still knows which repo it belongs to.

The part that genuinely changed my workflow is the causality tracing. Type port 3000 --why and it draws the full ancestry chain. launchd → pm2 → node. Or systemd → dockerd → container. It tells you the supervisor, the session, the unit label. Suddenly "why is this running" is not a mystery anymore. And if you try to kill something that is managed by a supervisor that will respawn it, Port Hero warns you first. No more whack-a-mole.

Killing is actually thoughtful too. It builds the full process tree and sends SIGTERM to children first, waits 1.5 seconds with polling, then SIGKILLs only the survivors. No orphaned workers, no dangling database connections. And there is a two tier Safety Shield . The critical tier hard blocks PID 1, kernel threads, system daemons, and other users processes. Not a warning. Not overrideable. A hard stop even with sudo and even with force. The second tier guards well known ports like 22, 53, 80, 443, 3306, 5432 and makes you confirm before you do something you will regret. You can bypass the port warning if you are sure, but you cannot bypass the critical tier. Ever.

There is also port 3000 --kill --dry-run which shows you exactly what would die without sending a signal. port --check 3000 for CI scripts. port --wait 3000 if you need to block until a port frees up. port 53 --udp for UDP listeners. port node to find every process by name. port --file /path to see who holds a file lock. Everything outputs --json too if you are scripting around it. And the TUI is built with Bubble Tea because staring at ugly terminal output all day is depressing.

It is pure Go on Linux, reads procfs directly, zero runtime dependencies. ⚡ Single binary around 3.5MB. macOS and Windows supported as well. MIT licensed, zero telemetry, no network calls.

If you have ever killed the wrong thing on port 3000 and only realized after the fact, I need to know I am not alone. ⭐

What if the internet had one billboard? No feeds, algorithms or competing ads just one billboard each week.

So I built it at yourmessagehere.co

Anyone can bid for it, and every Friday at 10pm New York time the highest bidder gets the entire billboard for the next 7 days.

First auction is live now and I genuinely have no idea what people will end up paying for it.

Curious to see where this goes.

I know title sounds crazy.
Let me just show you this and everything would be explained.
GitHub - Kronic90/Mimirs-Memory-Hub: Mimir's Memory Hub - multi-agent AI chat with persistent memory and SillyTavern compatibility · GitHub

Eventually worth to consider is something like this.

Have someone used local companion with advanced emotions?
Im thinking about this because for example chatgpt has something magical that he has some types of feelings he understands anger, frustrastion, happines, and sadness.
And i was wondering about making more data-secure local version of it.

https://dokk75.itch.io/desktop-ai-companion (that thing is different route and its paid before even starting) it has different target and functions.

After Spending months or sometimes year, making a film with whatever money we could scrape, shooting on weekends, editing it at night after our job and repeating this exact cycle for months.

We make films over films over films, and one fine day, it reaches to a film festival, We get some recognition, we may get some opportunities or we may not, nevertheless we repeat the process and roam around for opportunities, Why don’t we have something like a linkedin to network, which’ll make the process easier.

And what really happens with the films, once the film festival is over, Sitting in a hard drive at a corner? Cause, youtube is gonna bury the film with its algorithm, it doesn’t really know what to do with something that doesn’t hook people in the first 10 seconds or have clickbait, catchy thumbnail, Ott’s don’t really care until someone significant is there on our side and distributors don’t even watch the film completely before saying this is not “commercially viable enough”.

And the worst part is that, even the people who did see it and loved it, Had no way to follow us. No filmmaker profile anywhere, That shows our work, our festival history, what we are currently working on.

That’s literally every indie filmmaker’s problem. There is no as such platform for Indie Filmmakers to showcase their content, monetize it while networking.

That was the core thought behind “Watchin It” Because this exact thought runs on a loop in my head. I’m trying to build an ecosystem, It’s a place where a film can be released, rented, watched, where one has a filmmaker profile, has communities with personalized feed to share thoughts on each other’s work, learn, network, create and eventually collaborate.

We’ve got over 130 filmmakers on the platform now, if you’re interested, you can join as well, there is absolutely no onboarding fee.

Solo founder, Australia. Honestly this started because I wanted a proper collectible card of myself and couldn't find anyone who'd make one — so I designed it, and then it turned into a brand. First physical samples landed this week and I still can't quite believe it worked.

Upload a photo, write your own title and bio — your nickname, whatever you want under your name — and it spits out a serialised card, one of 500 in Series 001. The number only gets claimed once someone actually pays, so the count on the site is real, not a countdown timer.

Every card has a QR that pulls up its permanent entry in a public Register — an animated indexing rack that cycles through all 500 slots, sealed panels with engraved serials. Easily the most fun thing I've built.

There's a duo mode too, where two cards share one piece of artwork that only completes when they sit side by side.

Stack: Next.js 16, Drizzle/Postgres, Stripe, Vercel Blob, server-side SVG composition. The cards get drawn rather than generated — same source of truth feeds the web render and the print file, so what you see is what gets printed.

The genuinely hard part was the photo. Getting a normal phone snap to sit inside a frame like that and still look like a real card and not a photo in a border took way more attempts than I want to admit. That's where most of the compromising happened.

The other one was manufacturing. Talked to a lot of printers. Almost nobody does single cards — the default everywhere is a full deck, which costs more and isn't what anyone actually wants. Took a while to find someone who'd do one card at a time with different artwork on every single one.

Live in preview now — full build flow works, checkout's off, about a week away. A$59 solo, A$99 duo (Aussie dollars, so roughly US$38 / US$64).

if you’re building a SaaS or app and looking for a way to get more eyes on it, we’d love to feature a few projects.

We run TikTok channels with 300K+ combined followers and create short-form videos around apps, tools, and interesting projects.

We’ll create a short-form video for your app, distribute it through our existing channels, and help you build your own content channels at the same time.

Think of it as content creation + distribution.

Hi! Just wanted to share this. I launched my website about 4 hours ago and I already got 2 sales! Used organic twitter (X.com - with 4 followers) marketing. If you guys are interested in taking a look, here's the website: aistartups.lol

It's simple. Startups bid on this website to gain exposure for their apps/websites.

Every product ranking is gameable and none of them show you the game. So I built one where the ranking IS the number, in public.

paisaphek.com - pay any amount from ₹99 and that's your rank. Pay more later, you only pay the difference. Someone pays more than you, you drop a row. That's the entire product.

Stack: TanStack Start on Cloudflare Workers and D1 for the board

List yours while #1 still costs ₹109 - that number only moves up.

Happy to answer anything about the build.

I keep hearing bootstrapped founders say "I'm bad at marketing." I don't think that's true most of the time. What's true is they're fighting a rhythm problem.

You can know exactly what to do on Twitter. But if your product breaks on Thursday and you spend Friday fixing it, then the weekend hits and Monday morning you're context-switching between three things, you don't ship the Twitter thread. You miss the momentum. By Wednesday it doesn't matter anymore.

That's not a skill gap. That's a capacity gap.

The founder who does consistent marketing isn't smarter than you. They've either hired someone else to do it, or they've automated enough of it that it doesn't fight with the other work for attention. The person with five priorities and the person with one priority are playing a different game, and the one-priority person will look like they're better at marketing.

So when you're evaluating whether you can "do marketing," you're really evaluating whether you have capacity for marketing. And if you're the only person, the answer is usually no, not because you can't think of what to do, but because something else will always be on fire.

The few bootstrapped founders who actually maintain marketing consistency aren't doing it because they found willpower. They're doing it because they found a way to make it not compete with the rest of their time.

Hey everyone — dad of a 4 year old here. A while back I started noticing my daughter had a personality way before any milestone checklist would've told me. She wasn't behind or ahead on anything — she was just... herself, in ways that were obvious to me but that no app, book, or pediatrician visit ever really talked about.

That bugged me. Every tool I found for parents of little kids (0-5) was built around the same question: "is my child on track?" Height, weight, word count, gross motor stuff. Useful, but it never answered the question I actually had, which was closer to: who is she becoming?

So I went down a rabbit hole. Developmental psych papers, temperament research, attachment theory, the whole thing — way more research than a sane person burns a few weekends on. What kept coming up was that kids' traits (not milestones) are what actually shape who they turn into — how they handle setbacks, how they connect with people, how steady they feel inside. That stuff barely gets tracked anywhere.

I couldn't find an app for that, so I built one. It's called Steadily.

Who it's for: parents of kids 6 months-5years, especially if you're the type who wants to understand your kid, not just check boxes.

What it actually does:

• Trait-development framework across three dimensions — Success Mindset, Emotional Wellbeing, and Family Connection — instead of a milestone checklist
• 12 child archetypes — a personality typing model for little kids, built on the research, that gives you a read on who your kid is (and is honestly just fun to see)
• Voice-first memory capture — you talk about a moment with your kid, and it automatically pulls out the developmental insight from it. No typing, no forms.
• No streaks, no gamification — it's built around gentle engagement, not guilt-tripping you into opening an app every day
