Products that do what Open-source Percy/BrowserStack alternative does
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…

Hello HN. This is a project me and some friends built at university in 2017. It was originally built in a rush, but we've added a few improvements over the years. It's a fun game to host at a demoparty and project on a big screen - We did that at Instanssi many times. The implementation is still rough, and suffers from the fast pace of the modern web - The frontend is likely very outdated, and the backend is built with Vapor 2 and Swift 3.1, both no longer supported. You can host this yourself, but it might be a bit of a pain to set up. The WebSocket protocol is fairly trivial to work out…

Hi! Recently I've launched - mybfio.io - platform for software reviews with social network aspect. Prehistory Many great system are already in place that allow people to search and rate software products, including the site I am publishing this post on. However I have always felt that those systems are not specifically centered around product/software development lifecycle (releases, real users feedback over a product entire lifetime, so on) and often too broad or not designed specifically for that type of work, which is ok. Why? As an opensource author I would like to have constant…

Hi HN, After watching a lot of Show HN's here, it's finally my turn to show something. This is the first real project I have shipped, so it is extra special to me. For those who will inevitably ask why I made yet another mockup editor I covered it on our blog (http://blog.mocktailsapp.in/why-build-yet-another-mockup-editor-tm). Not all the features mentioned in that post have been implemented yet. As such Mocktails is pre-beta software and very minimal. It does not even have user accounts or any actual server side component at all for that matter (yet)! Our intention is to build Mocktails…

Hi HN, I built Reviewskits because of a recurring frustration I faced while working for a web agency in Switzerland. Our designers created beautiful, pixel-perfect layouts, but when it came to testimonials, we were stuck with rigid, pre-made widgets from tools like Senja or Trustpilot. Hacking them with CSS to match our UI was a nightmare. When we looked at their API pricing to build our own components for 100+ clients, the cost was astronomical ($90 to $300+/mo). Later, as an indie dev building my own SaaS, I simply couldn’t afford those prices. So I built Reviewskits: High…

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…

Hi Everyone, I've just launched my new web app BugMuncher - http://bugmuncher.com - which allows any website to have Google+ style visual feedback. (For those who've not used the Google+ feedback tool, it allows you to highlight an area of a page, as well as censor private information and automatically generate a screen shot which is sent with the feedback). Of course, Hacker News is the first place I've submitted it to, and I'd love your feedback on everything from design and usability to price. Having seen it written on these pages time and time again, I've gone for the most basic…

Hi All, I’ve been working on an open-source SDK to make collecting user feedback on your website less painful. Instead of wasting time on building your own feedback system and boring forms, my SDK lets users leave feedback directly on your website—with all the context devs actually need. Here’s what it currently does: Users can select any element on the page Auto-captures logs, metadata & screenshots Sends instant notifications (Slack, Discord, etc.) Lets you reward users → boosts engagement & conversions Gives users a tracking link → builds accountability & trust Self-host + customize the…

Hey Friends, I always considered doing a show HN about this but never took the jump but since we're in the Show HN carnival I decided to share it. I wrote a free and open source quick guide to teach Firefox OS application development. With this ebook you go from zero to a little application in the Firefox Marketplace. https://leanpub.com/quickguidefirefoxosdevelopment/ I created this to give away at hackathons and hack days because the Mozilla docs were spread all over the developer hub, mdn and the wiki so it was hard for new developers to find what they needed. 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…

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!

Hi HN! I built a free pixel art editor that runs entirely in the browser — no install, no signup, no watermark. The frontend is open source (MIT): https://github.com/comficker/simplepixelart What it does: - Sprite editor with layers, selections, mirror drawing, and an infinite-canvas workspace (multiple boards on one desk) - Frame-by-frame animation with onion skin, per-frame duration, GIF and spritesheet export - Tileset builder that auto-generates Wang-16 and blob-47 terrain sets from a single base tile — exports Godot 4 TileSet, Tiled .tsx, or PNG+JSON — plus a tilemap…

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.…

I’ve spent the last few days prototyping a browser-based game engine stack designed for instant-load, "Roblox-for-Teens" style deployment. The goal is to lower the floor for AA indie devs who want high-fidelity physics and instant web distribution without the overhead of Unity or a heavy Godot export. The Stack Engine: A headless WASM/WebGPU implementation. I’m currently using custom flags and selective streaming to bypass standard browser memory and execution limits. Physics: I’ve ported Jolt (Guerrilla Games) but modified the solver to mimic the original Blam! engine (Bungie/Halo…

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

Hey everyone, my friend and I created a GitHub Wrapped video for developers to showcase their activity on the platform in a more fun way. The implementation is open-source (https://github.com/rendleyhq/github-wrapped-2024) if you're interested in how it was built. To get a bit geeky, we used masks, keyframe animations, luma key shaders to remove the background from the confetti video, and some other techniques. Also, everything is rendered directly in the browser!! I'm curious to hear your thoughts on the rendering performance, especially if you're running this on your…

We've got a "launch" planned via a few partners here in town, from which we expect a significant amount of domain-specific traffic (i.e. a buncha designers). We'd love to get HNs take on our landing page from a marketing perspective and, if you feel so inclined, the functionality we have in place within the app. I've disabled the private beta lock such that if you register an account you will have immediate access to the app. You can find the landing page at http://www.pixelstew.com If you have any questions about anything at all please don't hesitate to ask!
