the video is for 49agents, an open source agent ide. 36 seconds, no sound, first frame is the same as the last so it loops forever. the harness is not a prompt. claude code writes the beats and builds the motion as dom and svg on one timeline. drop your url in the comments and i will try to make you one for free . i read what your product does, build the film, send you the mp4 at 1920x1080. yours, use it wherever you want. no card, no quote after. the harness is new. i want to know if it ...

I have been building FormsReach in leftover hours. It is a form API / contact form backend. Point your website form at it. Instantly live. No style changes, no extra backend. Submissions can leave through email, WhatsApp, Telegram, Discord, Google Sheets, or a webhook. Midway through, Zeno Rocha (CEO of Resend) posted that if he started again he would pick a boring infra problem, because lazy giants have leftover SDKs and confusing docs, and that is the whole product in an agent's eyes. ...

If you’re recording a tutorial, demo, or stream, it’s often useful for viewers to see exactly what you’re pressing without breaking their focus. That’s why I built Keyty - free, open-source native macOS app that displays your keyboard and mouse input directly on screen. A few things it supports now: - keyboard overlays with different themes and layouts - mouse button and click visualization - customizable size, position, and appearance It’s built in Swift, runs locally, and is completel...

The site: https://strategicallyempty.com I kept seeing headlines about the Strategic Petroleum Reserve and couldn't find a straight answer to "how much oil is actually left." So I built the answer: live countdown, official EIA weekly data, every chart explained, deliberately naive math with the formula published. Launch story so far, for anyone who likes the numbers: - Posted to r/dataisbeautiful . Top of Rising in 40 minutes, 3k upvotes, 96.2% upvote ratio, 400 shares - The...

The thing I built is for a fairly niche audience. It is ready enough to be useful to someone, however I struggle to get anyone to actually test it. So far everyone that creates an account has just finished the instruction panels at best. Where do you go to get the first few beta users on your app?

I just finished building this today. It's a website that shows you real sunrises 24/7 from a variety of cameras around the world. All live. No looping or recordings. This is a 100% passion project. Not a business. So it's just for the vibes. https://www.livesunrise.io/ FYI, this is a sister site to a similar one for sunsets that I posted here a few months ago if anyone remembers. Somehow sunrises are a bit nicer

So this one took a weird path. I started it as an anniversary gift. Pulled together years of photos of me and my wife — us, the kids, holidays, even the dog — and turned them into one big mosaic image. Posted it to my WhatsApp status and a bunch of people were like "wait I want one of these." Cool, I thought, there's a product here. Built it out properly. Subscriptions, everything rendering in the browser canvas so it was fast. Launched it. Crickets. Not one signup. Made it fre...

I liked the Grok bot avatar when it came out and wanted to see if I could rebuild it in SVG. It ended up as a small morphing editor. There are 14 animation states and they morph into each other. You customise the avatar by picking a shape, a colour and an expression, then chain the states on a timeline to build your own animation and export it as SVG, PNG, GIF or MP4. It’s in English, French and Chinese. My goal is to turn it into a library you can drop into your own project, so the avatar r...

Many PDF documents contain colorful charts, presentations, marketing materials, scanned pages, or graphics that aren't always ideal for printing or archiving. In some cases, converting a document to g

I can recall the time when I first put on the Oura Ring and checked my readiness score the next morning as if I were checking an exam score. I saw something like 62 and I really started to panic. Was

A trading research agent can write strategy code, run a backtest, inspect the results, and keep revising the strategy. The harder problem is making sure that this loop doesn't turn into an uncontrolle

Discord bots can look surprisingly complicated when you see them in action. A bot can respond to messages, tell stories, remember parts of conversations, and stay online around the clock. When I first

Building AI agents with raw LLM SDKs works fine for prototypes until you need structured outputs, testable code, and production reliability. The gap shows up in a predictable way. Your notebook code w

I have seen legacy migrations considered successful because the old framework disappeared from the repository. Six months later, the team was still dealing with the same coupling, the same unclear bus

In this tutorial, you’ll build a practical AI agent that can receive a user prompt, decide whether it needs to use a tool, execute that tool in PHP, store conversation history in MySQL, and continue r

You've seen it a hundred times: the Wi-Fi drops, Chrome shrugs, and a little pixelated T-Rex appears, ready to sprint through a desert the moment you hit the spacebar. That tiny game, hidden behind th

Every B2B SaaS product with a compliance requirement (like banking, lending, payroll, or crypto) hits the same wall early on: before you can let a business use your platform, you need to verify who th

When learning C, it's easy to get stuck building text-based terminal applications that simply ask for user input and print a result back out. While those are great for learning the basics of the langu

Whether you're designing robotics, analyzing fluid dynamics (CFD), or working through complex engineering data, learning to code is one of the most effective ways to boost your workflow and technical

Sometimes you don't want to change the actual content of a PDF. You simply want to add a colored layer over part or all of the document. This can be useful for creating branded reports, adding colored

Today, diffusion models have become one of the most influential families of generative AI systems. They power applications ranging from image synthesis and editing to video generation, scientific disc

PDF editing isn't limited to adding signatures or merging documents. Sometimes you simply want to improve the appearance of a PDF by increasing brightness, boosting contrast, adding blur, converting i

When your AI agent serves more than one person, every tool call must answer: who's the agent acting for? Let's learn how to solve this by building an AI agent that connects with Slack and GitHub. A Sl

Picture this: it's 4pm on a Friday, and your team has just merged the last feature for the sprint. But your product manager asks for a new build on TestFlight by the end of the day so the client can r

Causal inference for LLM-based AI features is no longer theoretical. Airbnb, Netflix, Lyft, and Uber have published detailed engineering blog posts describing exactly how they measure the causal impac

Hi all, I'm the owner of KrakenKeys , a free Steam game price comparison platform. It compares prices from over 20 stores, to help gamers find the best deals. I didn't want to gatekeep the data, so I decided to open a free public API. Documentation / spec: https://krakenkeys.com/api-docs Postman collection: https://www.postman.com/krakenkeys-4130662/krakenkeys-api/overview With the API you can: - Search for games - See the current (best) prices for games, including historica...

Looking back, what’s one decision you overthought that ended up not mattering much? Or the opposite, something you barely thought about that turned out to be really important. Curious where founders actually end up wasting the most time.

Creator disclosure: I built Codepend. It’s free, MIT-licensed, and has no paid tier. Claude Code, Codex and Cursor leave session histories on your machine. `npx codepend` turns them into one self-contained HTML story: first prompts, late-night sessions, repeated phrases, abandoned projects, timelines, and a Wrapped-style archetype. Codepend reads those files locally, writes nothing back, and has no backend or telemetry. The attached 40-second video was generated by Codepend from invented dem...

(Yes, Reddit auto-assigned me the username "Desperate-Ad" and no, I couldn't make that up if I tried.) Nine years ago I went to a wedding where the only people I knew were getting married. My date and I spent the whole weekend wishing we could see who else was there, when people were arriving, what anyone was doing between events. That app didn't exist. I never stopped thinking it should. I'm a video editor/VFX artist by trade — 12+ years, zero coding background. Six months ago I f...

Hey everyone! Last week, I reached a huge milestone by launching my app, Mosaic News, on the iOS App Store! Mosaic News is a free iPhone app that aggregates news reporting from more than 850 publishers across the political spectrum, groups coverage of the same event, and connects individual events into larger narratives to help readers “see the whole picture.” I started building it because I was frustrated by how difficult following the news had become. Misinformation, media bias, conflict...
