If you've ever loved the speed of building backend servers with Express.js, but wished you didn't have to guess at types or debug silly runtime errors, we just posted the perfect tutorial for you. Our

When developers transition from the relational world (MySQL, PostgreSQL) to Firestore, Firebase's NoSQL document database, they often bring their old habits with them. They try to replicate tables, fo

Two years ago, AI coding tools were a curiosity. Agencies let junior devs experiment with them on internal tools and side projects, the kind of work where nothing broke if the code was bad. Client wor

I’m not sure what to do with this next. I originally built it for my own use, but now I’m considering taking it to the next level. However, I’m uncertain whether it’s the right direction or if similar solutions already exist in the market. One thing I’m proud of is that I taught myself how to develop all of this using AI tools. I’d appreciate any suggestions on the best next steps—whether I should continue developing it, validate the idea with potential users, or explore the market first. K...

Hey y'all. I've been building this website wafplanet.com for a while now (basically, since dec '25, when opus 4.5 came out), and it kind of blew up in my face in terms of traffic. Wafplanet is a website about web application firewalls, one of the most boring, but quite important to people with dynamic websites - a WAF is a piece of software that tries to block bad actors / people that try to hack your website in an automated fasion (it's stuff like cloudflare, basically). I'm not quite ...

I built a Chrome extension called Bous . It gives you a Stremio/Nuvio-like experience without needing to install a separate desktop or mobile app. How it works: Click the extension icon on any webpage and a sidebar opens with full movie/TV show catalogs Search for any title and get detailed info — cast, trailers, ratings from multiple sources It adds a button directly on IMDb and TMDB pages so you can instantly load any title Why a browser extension instead of a desktop app? Y...

Hey all. I'm a journalist who made the leap into coding in recent years. I'm on the job search currently so I've been busy making projects to build up skills and test the capabilities/limitations of AI. My latest project is stillintheloop.com - it's an experimental AI-assisted newsroom where I have created agents (backed by skills) that work as beat reporters, desk editor, photo editor and copy editor. The main catch, is that there is always a human in the loop (me) that acts as the m...

I am sure many of you have had perfectly good food rot in the fridge and/or have had to clean up afterwards (on top of throwing this away)... This was a massive problem for me for a long time. So...I decided to build an app that keeps track of groceries. After a few attempts, added a scanner to get the list directly from receipts and recipe suggestions. I put it on the App Store (it's called SmartFridge, free to use) and figured I'd share it here in case it's useful to anyone else. Link bel...

I have been generating a lot of websites with AI coding tools, and I kept running into the same problem. The code was usually usable, but the design looked like every other AI-generated landing page: the same gradient, the same font, the same card layout, very few visual assets, and no consistent visual direction. You can obviously get a better result by giving the AI several references, carefully choosing the fonts and colors, generating assets separately, and spending hours refining the pr...

Every 30 days, over 1 billion people open Google Translate to translate text, documents, or screenshots. The problem? Context and accuracy. Even for basic text, legacy tools regularly make critical errors. You end up having to proofread the translation, but if you don't actually know the target language, you're stuck hoping for the best. With documents, the layout might look fine, but the meaning is often broken. That’s why we are building VertoX. We are not building another language-l...

Being upfront: I'm not doing this for karma or portfolio. I want to build a small tool and sell it, even if it's $9/mo and 20 people. That's the goal. What I don't have is an idea worth 2 weeks of my life. So — tell me about something that costs you money or hours every week that you'd hand over a card for. Specific, from last week, not "I wish I was more organized." Three things make an answer useful to me: What is it — "I spend 40 min every Monday pulling numbers from 3 ...

hi, here is my take: up to 80% of web traffic is mobile, yet we still build and present on desktop. dev tools exist, but honestly they're pretty clunky for designers or non-technical folks. so I built a free chrome extension that shows mobile and desktop side-by-side in one click. thought about it, built it. if anyone finds it useful: https://dualpreview.com tbh, building it was way easier than marketing. I've read tons of threads here but still feel like I have no clue what I'm doing. it'...

Our platform had unlimited ai task evaluations per day, we capped it to 2 ai evaluations only per day and saw a decline in daily task completions from users. We did this to make sure we don't burn out a lot of credits people using it for free, at the same time, we did not want users to feel the platform is too restrictive to use for free. These are task evaluations for real job scenarios, for context, I need your opinions and feedback on what could be a suitable number, or any other way we c...

Built a voice-controlled desktop assistant over the past several months. The kind that listens, responds, opens apps, reads files, handles tasks while you talk. Technically it worked pretty early. Like embarrassingly early compared to how long I kept building. The real bug was me explaining it wrong to everyone. I'd demo it and people would go quiet in a good way. Then I'd open my mouth and say something like "it's like an AI assistant but actually useful" and watch their eyes gl...

I keep refreshing my admin dashboard like it owes me an answer. Same user count. Refresh. Same guest activity. Refresh again. Then suddenly, a new registered user. For a few seconds, I genuinely got excited. Someone had found the app, stayed long enough to understand it, and decided to create an account. Maybe something was finally working. Then I opened the user list. The new registration was me. It was a test account I had created earlier to check whether a change in the ap...

Before: https://imgur.com/a/5bzd9OK After: https://imgur.com/a/1KjKWnE I'm the founder of Quickpages.co , which was made 10 years ago. It initially had massive traction somehow and continued getting views for many years thereafter. It ranked #1 on "Free landing pages" and got most of its views from Google & other sites writing articles about it. Me, being a really lazy developer and having full-time jobs, and not being interested by the problem (technically speaking), I ...

Hi Folks! More year our small indie team has been building Synvector , a sci-fi action RPG that tries to combine several ideas we always wanted to see in one game. Instead of controlling just a single ship, you command an entire mercenary fleet. During combat you can pause time, issue tactical orders to your squadron, switch between ships, and then jump straight back into fast-paced third-person space combat. Our biggest inspirations are: Everspace Elite Dangerous Mass Effect Mo...

I've been building this clock site on the side for the past 6 months. It started as just wanting a nice Fullscreen clock and turned into something bigger. - iloveclock.com The main idea is customization. Right now, it has about 24 clock faces, 11 themes, and 17 animations you can mix and match. You can also set a background — your own wallpaper, some preset art ones I added, or a YouTube video (I put in a few lo-fi ones). There are small CSS effects too like rain and snow. It has an always-o...

Do you ever wish there was something between Venmo and Uber Eats? Sometimes a friend has a rough day, or someone helps you out, and I want to send them a specific coffee or matcha, but delivery forces them to drink it immediately, and a gift card feels kinda impersonal. I built Spot around this idea and would love feedback if anyone’s interested.Spot lets you: - Choose a specific drink or snack from a local café - Send the gift inside your iMessage conversation - Recipients save it to...

Hey everyone! So, as the title says, I've built a clean open-source poker website/PWA! Having recently gotten back into poker, I ended up trying a bunch of existing apps and websites and most of them ended up being fake felt, flashing "BUY CHIPS" buttons and many, many pop-ups. So, over a weekend, I built Pip - single-player Texas Hold'em, redesigned to respect you: No real money, ever. Play-money chips, no $ anywhere, nothing to buy. It literally can't take your money....

I've used lazygit for years and love it, but a handful of things always bugged me. I started building a git TUI in Zig to learn the language, and ended up fixing them. It's now what I use every day. It follows lazygit's workflow, so it's instantly familiar. Here's where it deliberately does things differently: - Nothing ever blocks. Fetch/pull/push and slow rebases run off the UI thread with a spinner while you keep navigating. Success is silent; only failures open a dialog. No "press...

​ I've been working on an explainer video tool for a long time, but it only supports on uploaded docs. I'm pretty active on Twitter, and every time there's a new announcement from OpenAI or Anthropic with a blog article, I never read those. So I got an idea to convert them into video posts in the comments, and people loved it. So I added that as a feature. Now you can upload any article or blog link, and it can make a video for you. Website: "distill book(.)com" &#32...

Not necessarily making money.Maybe it was your first returning user,someone recommending it without being asked,or just realizing people genuinely cared.What was that moment for you?

I'm fed up. I'm developing projects (SaaS, mobile apps) and looking for people who are interested in what I'm doing. But I'm not getting any responses. Even though it's free to be a tester, I'm still getting nothing. So I don't know what to do. I don't know if I should stop working on these kinds of projects. I'm just fed up.

I'm a huge fan of augmented reality games like Ingress and Pokémon Go. I've always dreamed of building my own version, but until about a year ago, it simply wasn't possible. After several months of work, I've finally finished my own Pokémon Go version. The biggest challenge was placing 247 million points all around the world while avoiding dangerous or inaccessible areas such as roads, lakes, houses, and private property. To solve this, I built my own algorithm using OpenStreetMap data. Afte...

A month ago, I decided to put all my energy into SpacePlanner and try to turn it into the #1 free, no-sign-up space planning app that actually gives people real value. Since then, it has grown to more than 200 daily users and over 1,500 plans created, and few hundred guest users! The last few days have been intense, mostly fixing bugs, improving stability, and trying to make the editor less frustrating. I also think I may have overengineered some features that people do not really need. I ...

Why? For years we've had open formats for documents (PDF), images (PNG) and graphics (SVG). But user interfaces are still mostly locked inside design tools. And that was fine when humans were creating and consuming UIs. Now AI is also creating and consuming them. Today AI usually works with screenshots, editor-specific JSON, or tool-specific APIs. They work, but they weren't really designed for AI or for moving designs between different tools. So I started building . gui . The idea is si...

I'm a bit torn on how to approach this because a customer is a customer and you all know how difficult it is to get them, but I don't want my saas to get a weird or bad reputation. My startup is an authentication and paywall software that allows creators to lock their content until someone signs up or purchases. It's usually used by digital goods stores or online courses. However recently there have been a lot of people using it for purposes not entirely foreseen when I created it. I am caut...

You've built and consumed APIs. You know what a GET request is, what a JSON response looks like, and how to add an Authorization header. You've used REST, maybe tried GraphQL, and perhaps heard of gRP

Imagine your team deployed Prompt A globally two weeks ago. Tight deadlines and high confidence meant the rollout hit 100 percent of users without any A/B testing, shadow traffic, or holdout groups. W
