   BrowserOS – "Claude Cowork" in the browser▲88

   Hey HN! We're Nithin and Nikhil, twin brothers building BrowserOS (YC S24). We're an open-source, privacy-first alternative to the AI browsers from big labs. The big differentiator: on BrowserOS you can use local LLMs or BYOK and run the agent entirely on the client side, so your company/sensitive data stays on your machine! Today we're launching filesystem access... just like Claude Cowork, our browser agent can read files, write files, run shell commands! But honestly, we didn't plan for this. It turns out the privacy decision we made 9 months ago accidentally positioned us for this…

    Owl Browser▲145

    I've been working on browser automation infrastructure for a while and kept hitting the same ceiling: Playwright and Puppeteer are great for scripting but fall apart when you need stealth at scale. Cloud-based solutions like Browserbase work but you're sending all your data to a third party and can't control the environment. So we built Owl Browser, a self-hosted Chromium-based engine that runs in a single Docker container. The core technical problem we tried to solve was fingerprint consistency. Most browser automation tools either ignore fingerprinting entirely or apply surface-level…

    We Put Chromium on a Unikernel (OSS Apache 2.0)▲132

    We’ve been building infrastructure to spin up browsers for AI agents. Originally, we built[0] it as a pool of warm Docker containers running Chromium, exposing: - Chrome DevTools Protocol (for Playwright/Puppeteer) - noVNC (for live view) We’ve been following the unikernel space for a while, so we decided to see if we could get our image on one. We went with Unikraft Cloud[1]. Here’s how it did: - Boot-up time: 10–20ms (vs. ~5s for Docker containers) - Near 0 CPU/memory consumption when idle - Still ~8GB RAM when active (headful Chromium) Potential use cases: - Standby mode during…

    We packaged an MCP server inside Chromium▲46

    Hey HN, we just shipped a browser with an inbuilt MCP server! We're a YC startup (S24) building BrowserOS — an open‑source Chromium fork. We're a privacy‑first alternative to the new wave of AI browsers like Dia, Perplexity Comet. Since launching ~3 months ago, the #1 request has been to expose our browser as an MCP server. -- Google beat us to launch with chrome-devtools-mcp (solid product btw), which lets you build/debug web apps by connecting Chrome to coding assistants. But we wanted to take this a step further: we packaged the MCP server directly into our browser binary. That gives…
