Products that do what Linden – Self-healing Playwright scripts at scale does
Justin and Avichal here. We’re building Linden (http://trylinden.com), a tool for maintaining browser automations at scale. Avichal lived this problem at a dental insurance startup, where he spent time fixing brittle Selenium scripts that broke on minor website updates. He was pulling data from dozens of legacy portals and the constant maintenance was a drain on engineering time. The new AI browser tools had their own issues. We found them to be mostly black boxes, lacking the observability and control needed for business-critical pipelines. We're building Linden with a different…

Hi HN, I’d like to share an open-source project we’ve been working on for a while: Browser4. The motivation came from a recurring frustration: most browser automation tools (Playwright, Selenium, Puppeteer) are excellent for human-written scripts, but start to show friction when used as a core execution layer for AI agents or at very high concurrency. So instead of building “another wrapper around Playwright”, we experimented with a different direction: designing a browser engine where AI agents are first-class citizens. ### What Browser4 is Browser4 is a browser automation engine built on…

I'm Tyler - the solo operator of Quanta Intellect based in Portland, Oregon. I recently participated in Nous Research's Hermes Agent Hackathon, which is where this project was born. I've used agents extensively in my workflows for the better part of the last year - the biggest pain point was always the browser. Every tool out there assumes a human operator with automation bolted on. I wanted to flip that - make the agent the primary driver and give the human a supervisory role. Enter: Vessel Browser - an Electron-based browser with 40+ MCP-native tools, persistent sessions that survive…

Hey folks, today we at Currents are releasing a brand new AI skill to help AI agents be really smart when writing tests, debugging them, or anything Playwright-related really. This is a very comprehensive skill, covering everyday topics like fixing flakiness, authentication, or writing fixtures... to more niche topics like testing Electron apps, PWAs, iFrames and so forth. It should make your agent much better at writing, debugging and maintaining Playwright code. for whoever didn't learn about skills yet, it's a new powerful feature that allows you to make the AI agents in your…

As a software engineer, my reflex has always been to script everything I can. Scripting is easy, but everything around it is tricky: scripts have to run somewhere, they need access to credentials, they need to be monitored. None of it is simple. No-code automation platforms such as Zapier or IFTTT are too restrictive for technical tasks; CI/CD platforms make it easy to script tasks related to a repository, but are limited when trying to do anything else. I wanted the low level control you have when writing scripts while retaining the comfort of a platform managing execution for me. So I…

Hi HN, I'm one of the creators of Nanobrowser, an open-source Chrome extension that lets you automate web tasks using AI agents. We were inspired by the potential of tools like OpenAI's Operator, but we wanted something that was: -Open-Source:You can see the code, modify it, and contribute to the project. -Browser-Based:No complex setups or server deployments. It runs directly in your browser. -Customizable:You can tailor the agent's behavior to your specific needs. -BYO LLM:Bring your own large language model API key (OpenAI, Anthropic,or even local models), No vendor lock-in. -Privacy…

I built this because I was tired of creating pull requests in 20 repositories just to change a single line of workflow job version. With Infra as AI, just mention the change. Agents work on all repos in parallel, read the docs, make a bunch of PRs and fill in the description. You can see the demo of the actual dashboard in the landing. Let me know your thoughts :) It means a lot to me!

Hi HN I built a fun little tool: It uses Groq’s LLaMA 3.3 + Puppeteer to analyze a website Then it roasts the design/content/UX with humor And finishes with 3–5 genuinely helpful improvement tips You can try it here: https://ai-roast-vert.vercel.app I wanted to: Practice fast idea-to-launch cycle (built in 2 days) Experiment with a viral-friendly product Monetize with a $0.55 pro version that gives a detailed roast + download Would love your feedback — on the idea, the tone, the usefulness — anything! Thanks in advance

Hi HN, Zidan here. I’ve been experimenting with AI-assisted debugging and noticed a recurring gap: most tools optimize for agent-led exploration (ex: giving claude code a browser to click around and try to reproduce an issue). But in many cases, I've already found the bug myself. What I actually want is a way to hand the agent the exact context I just saw - without retyping steps, copying logs, or hoping it can reproduce the behavior. So we built FlowLens, an open-source MCP server + Chrome extension that captures browser context and lets coding agents inspect it as structured, queryable…

Hi HN, I’m still in college and new to the startup world, but here is my first shot at a side project: Milburn, an integrated therapy+journal tool(https://milburn.vercel.app/). I built Milburn bc every mental health tool I could find was missing something: the therapy apps didn’t have voice/memory/too expensive, and the journal apps were always a PITA to sync with therapy. We trained the chatbot’s model on specific therapy modalities(I personally need CBT sessions, but we also have others like DBT), and then created a prompted journal, added a feedback loop, voice…

Hi HN! We're excited to announce the public beta of Mowgli, a spec-backed, AI-native design canvas for scoping and ideating on products. The productivity gains unleashed by coding agents have made everything else an unexpected bottleneck. In an effort to make the most out of this new paradigm, we ceded a lot of ground in product thinking, thoughtful UX, and design excellence. In other words, the pace of tooling for deciding what to build has not kept up. Mowgli is inspired by, in equal parts, Figma and Claude's plan mode. It evolves a detailed specification and designs for every screen and…

I've built a job platform for technical roles called "Cracked Engineers". If you want to land a job with some of the world's best AI/tech startups - my goal is to make this the go-to place for that. YouTube walk-through can be found here: https://www.youtube.com/watch?v=XmuIOdES7mQ A huge thank you to Weaviate (Bob van Luijt & team), Unsloth AI (Daniel Han & Mike), OpenPipe (David Corbitt), Julius AI (Rahul Sonwalkar), Jimini AI (Luis F Voloch) for using the platform while in beta and posting first paid posts. So, why did I build it? Well, over the past period a lot of…

I’ve been building LLM tooling for a small VC fund and found myself explaining the same mental model over and over to non-technical people around me: how a stateless LLM becomes a chatbot, how tool use works, what an agent is mechanically, and why context windows shape all of it. I never found a guide that covered that full chain at the level I wanted, so I wrote one. It’s nine short chapters, each building on the last. Deliberately simplified: the goal is a useful mental model, not a textbook. Feedback, corrections, and contributions welcome: github.com/ymyke/aiaiai

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 all, Justin here. I previously built Phind, the AI search engine for developers. One of the biggest problems we had there was figuring out what went wrong with bad searches. We had tons of searches per day, but less than 1% of users gave any explicit feedback. So we were either manually digging through searches or making general system improvements and hoping they helped. This problem gets harder with agents. Traces are longer and more complex. It takes more effort to review them, so I'm building a tool that lets you analyze LLM outputs directly to help developers of LLM apps and agents…

Hi HN. I'm the founder of Phoenix Labs (ex TikTok, Applied AI) and we're open sourcing our internal tooling today which is like a toolchain / meta-harness for CLI agents useful for really scaling eng and creative work. We are a very small team who's building a very ambitious product so we had to find ways to squeeze every ounce of efficiency that we could get our hands on. Harness strengths of different models (Claude, GPTs) and CLI-harnesses (Claude Code, Codex), safe/robust browser integration to speed up UX/QA testing, teams cli to speed up security reviews and parallelize…

Hi HN! Sean from MindStudio here. I wanted to share something we've been working on that I think introduces some new ideas into the "AI coding agent" space. Remy is an AI agent that builds full-stack TypeScript apps from a spec written in a new flavor of annotated markdown. The spec has two layers: prose describing what the app does, and annotations that carry the technical precision (data types, edge cases, validation rules, code snippets). The agent then "compiles" this into code: backend methods, typed schemas, frontends, test scenarios, and everything else are derived artifacts of the…

Hey HN — I'm Michael from Decipher (https://getdecipher.com). We build infrastructure for autonomously generating and maintaining end-to-end tests. Today we’re launching our Claude Code integration. We built this because as teams ship more code, especially with coding agents, they need more regression coverage. Claude can already generate a decent Playwright file from a repo and prompt. That solves first-draft generation. It does not solve repeatability. A generated test is still a static guess. The real problems start when it meets the live app: the browser is logged out, a modal…

I've been working on a platform (tesse.io) that allows you to search global experts and connect with them via chat and video call. It works like an expert search engine, you can search by a keyword of skills or expertise and you get people as results. You can use it as a tool to search for someone that can help solving your issues, and you can also join as an expert if you are confident about your knowledge in a field (right now we have 3 fields, we will expand more soon), once you choose to be an expert you have a chance to earn money from sharing your knowledge and this's like a flexible…
