Headlamp is a Chrome extension that shows where you're missing tests. It reveals gaps in testing for solo testers, test teams (collaborative bug-bash, anyone?), and test automation (Selenium, Puppeteer, Playwright). Using it is easy as 1-2-3! 1) When you start testing, Headlamp puts a dot on each link and input element. 2) The dots are cleared when you click a link, type some text, or change a selection. 3) The remaining dots show you which things you missed. It also provides insightful test activity reports. It's free to use as a solo tester. Give it a try today!

Hey , I've created Pixeleye, a cross-browser visual review and testing platform. I've found the pricing of visual testing platforms quite absurd, with companies often opting out of testing their UI's across different browsers. We offer a cloud version of our product but also provide the tools to self-host it for free. We hope this will keep our pricing honest and promote a sustainable open-source community around the project. Some of our main features include: - Cross-browser testing - Lots of integrations: Storybook, Cypress, Playwright & Puppeteer - Permission syncing - We'll sync with…

Today I'm launching my project BugCam. It all started four years ago when I sent an email to the folks at Fog Creek Software, asking them to add a video capture tool, just like their screenshot tool, into FogBugz. Their response: that sounds awesome, why don't you build it! Well, here we are. We've been in private beta for 3 months, have some happy users, and we're ready to release BugCam to the world today! BugCam makes it easy to create bug videos and share them via your favorite bug tracking tool (at this point, Bugzilla, FogBugz, Gemini, JIRA, Redmine, Mantis, and Trac. Additional…

Hi HN, I’ve spent the last decade building hardware products like humanoid robots, 3D printers, and self-driving tractors. I needed a tool to navigate technical documents faster, so I created one with friends. This tool helps with component search, cross-referencing, comparison, and debugging. We’d love your feedback, whether you find it useful or not. Thank you! Try it here: www.convergelab.ai

Hello Hacker News! We've been working on Convoy Playground [0], a tiny proxy and debugging tool which makes testing webhooks a breeze. If you've ever struggled with configuring or troubleshooting webhooks, we believe this tool will be a game changer for you. Convoy Playground provides a simple, intuitive, and powerful interface for testing, debugging and replaying webhooks. You can send HTTP requests to your specified endpoints, view and analyze the response in real-time, and even replay the requests as needed. The inspiration for this project came from the countless hours we've spent…

As a side project for a hockey manager game, I created a small audio tracker, "HM Tracker," which was used to make the game's music. It is a browser-based tracker-style music workstation. All sound is procedurally generated from oscillators - no samples, no plugins. The UI lets you edit patterns on a step grid, pick instruments and chords, then export as a standalone JS music engine or WAV file. Built with vanilla JS and the Web Audio API (best experienced on a desktop browser). Made in the '90s demoscene spirit (at least the looks, anyway). Would love any feedback!

Hey folks, I am finally posting a Show HN post for a project I have been working on for several months now, and it's in a state where I already get a lot of value myself, so I am happy to share broadly. The pitch line is: "Skybear.NET is a managed platform automating Synthetic HTTP API testing." At the moment, the main source file format supported for your API tests are Hurl.dev files [1]. Hurl is a CLI tool wrapping `curl` and it's really awesome. At least check that out :) I am not affiliated directly with the Hurl CLI tool, and the platform I am building provides full Hurl compatibility.…

Hi HN, I'm the CEO at https://replay.io. We've been working on time travel debugging for web development for a while (https://news.ycombinator.com/item?id=28539247) and more recently an AI app builder that uses that debugger to get past problems instead of spinning in circles (https://news.ycombinator.com/item?id=43258585). We've gotten to where we can pretty easily build apps to replace business-critical SaaS tools, some of which we're now using internally: * We built our own issue tracker to keep track of all our development projects, tickets, bug…

Hello Hacker News! I’ve been working on a side project that ports the entire Source Engine to run in the browser using Emscripten. (Yes, the same engine that powered Half-Life 2, Portal, CSGO, and more.) It’s still a work-in-progress some features are missing and the launcher is in development but core engine functionality is up and running. I’d love feedback, ideas, or contributions. If you’re curious, feel free to check it out, star it, or open a pull request! Here's the link to the source code - https://github.com/OrbitaStudios/LambdaComplexSource

Hi HN! After several months of work, I'm excited to share ProKZee, a free and open-source network security tool built with Go and React using Wails framework. ProKZee allows developers, security researchers, and penetration testers to intercept, inspect, and modify HTTP/S traffic — similar to tools like Burp Suite, OWASP ZAP, and Caido — but with a fast native UI, modern UX, and some unique features. https://github.com/al-sultani/prokzee

Hey HN, I'm Damiano Rodriguez, and I've been working solo on a project called Caisual Games. It's a free platform where anyone can create web games just by describing them with their voice. Here's how it works: You simply describe your game idea ("Make a cookie clicker game with 5 upgrades"), and the platform generates a playable web game in seconds using HTML and JavaScript. There's no coding required and no downloads needed—you can create and play directly in your browser. What's more, anyone can improve a published game, fostering a collaborative environment for game creation. The…

Hey! I have been building CoderScreen, an alternative to coding interview platforms. I thought it was an interesting product to build with the evolution with all the sandbox products coming our for code execution, as well as me never being satisfied with existing platforms. The current features are: - Live interviews for pair programming exercises - Assessments for async technical screening It is built on Cloudflare primitives such as Workers, Durable Objects for the multiplayer experience, Sandbox for the code execution. Would love to get feedback on the current product, as well as hear…

Hey HN! Last week I was working on a website and needed a way to synchronise visuals with live music. I've used MIDI controllers for this before, but I am travelling right now and don't have mine with me. So I had the crazy idea to build a browser extension that uses the keyboard as input and includes a sequencer. I gave myself 24 to work on it. It ended up taking longer (of course), specially since I ended up creating a demo, a small landing, docs, and an intro video. Took me one week from idea to launch (pushed quite a bit tbh). Features: - Works as a browser extension. Atm distributed…

Hey HN! I develop browser extensions, I suck at web design, and I've been exploring AI/LLMs. With my new found free-time since dropping work hours, I've developed a Design Copilot browser extension [0]. It does what it says on the tin - you choose a part of your website and the tool gives you instant expert design feedback - "change this font to that, add this much whitespace, use brighter colours .... etc" The tool is completely 100% free to use, its powered by bringing your own AI API Key, and the current LLM it uses is Google Gemini 1.5 Pro. I've yet to hit the free rate-limit and I…

Hey HN, wanted to share a new collection of dev utilities that are ad-free, client-side (nothing leaves your device), with a command+k menu for fast search. github.com/jamdotdev/jam-dev-utilities Why? The sites we use every day for data conversion (e.g. PNG to data URI) are cluttered with ads, one of those mildly annoying things engineers deal with while writing code. This came up at a recent team dinner, and we got interested in creating nicer, modern, uncluttered versions of these tools. Since then, every time we needed a util, we added it to our stack. Lots more tools still to…
