24 alternatives to Open-source Percy/BrowserStack alternative
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…

Hey! My name is Dima, I am from Ukraine and I am the co-founder of Lost Pixel! We built this tool to solve our problems at work and decided to open-source it so more people can build their custom visual regression testing pipelines! If you want to chat about the tool or visual regression testing in general I am super excited to meet like-minded people! Thanks a lot for checking out the product and I hope it will serve you well if you decide to try it out :D

I built this out of frustration as I lead the development of AI features at Yola.com. Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process. And that's not all. Then came the pricing. The last quote I got for one of the tools on the market was $6,000/year for a team of 16 people in a…

Hey HN! I’m Robert. I worked on [Percy’s SDKs/support from 2018–2022.](https://github.com/percy/cli/graphs/contributors) If you ever reached out to support or opened an issue, I probably helped you. Hopefully it was positive :) After a few years away, visual testing still felt stuck, so I'm building Vizzly. The problem: Design handoffs kinda suck. Designers make beautiful specs, devs implement them, then everyone realizes the details got lost somewhere. Current visual testing tools catch broken CSS but miss the real issue - making sure what ships actually…

Hey all! I wanted to share this project I've been working on that can maybe help you or your developer friends out. I built a RAG system for our product a while back and didn't realize how easy they were to get started. So I put together my learnings into this online course. It's not quite ready but if you sign up and mention HackerNews, I can get you early access. I'm looking to get feedback on the following: (1) materials — is it engaging & did you learn something? (2) UI/UX of the platform — did you have any issues that prevented you from starting or finishing the tutorial? (3)…

Hi HN, I'm excited to share a project I've built: PixelateImage.org. Instead of being a traditional image editor, this is an *AI-powered tool that generates pixel art directly from your text prompts.* If you've ever wanted to create unique pixel art characters, scenes, or assets for games, art projects, or just for fun, but perhaps lacked the specific artistic skills or time, this might be for you. My goal was to make generating retro-style or modern pixel art more accessible. You can type in a description (e.g., "a brave knight in a dark forest," "a futuristic cityscape at night," "a cute…

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…

Hey HN, I built a REST API for capturing screenshots and generating PDFs from URLs. Why: I got tired of managing Puppeteer/Playwright in production. Memory leaks, zombie processes, Docker issues. So I wrapped it in an API. Stack: - Node.js + Fastify - Playwright (more stable than Puppeteer in my experience) - Self-hosted on Hetzner Features: - Screenshots: PNG, JPEG, WebP - PDFs: A4, Letter, custom sizes - Full-page capture, custom viewports - Cookie consent auto-accept - Lazy-load handling API example: curl -X POST…

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…
