Chromium fork with native AI agent support. YC S24 backed. Privacy-first agentic browser with 12 built-in AI skills. Supports 11+ LLM providers including Ollama for local models. Only credible open-source alternative to ChatGPT Atlas, Perplexity Comet, and Dia.

Score 82

Where it wins

Chromium fork with native AI agent integration — not a plugin or overlay

YC-backed with weekly releases: 47 releases in ~10 months, v0.43.0 on 2026-03-12

31-tool MCP server integration (v0.42.0); Skills, Memory, SOUL.md in v0.43.0

Supports 11+ LLM providers including local models (Ollama, LMStudio) — browsing history stays on device

314-point HN (Jun 2025) + 88-point thread (Jan 2026 as BrowserOS)

Only credible open-source alternative to Atlas/Comet/Dia

Where to be skeptical

~10 contributors despite YC backing — thin team for a browser product

AGPL-3.0 license may block enterprise adoption

Lane 4 (consumer agentic browser) — different market than developer automation tools

HN criticism flagged prompt injection risk

Editorial verdict

Lane 4 leader. Just crossed 10K stars. 314 HN pts with 206 comments is strong organic engagement. YC S24 backing. Privacy-first Chromium fork with built-in AI. Different market than Lanes 1-3 but clear leader in consumer agentic browsers.

<h3>Two browsers: one for your agents, one for you.</h3>

Free · Open source · Everything runs on your machine

</div> <details open> <summary><h1><img src="https://raw.githubusercontent.com/nxtscape/nxtscape/main/packages/browseros/resources/browserclaw/icons/product_logo_192.png" alt="" width="28" /> BrowserOS neo: the browser for your agents</h1></summary>

What is BrowserOS neo? A second browser, just for your AI agents. Import your logins from Chrome in one click, connect Claude Code, Codex, or any MCP agent, and hand off your web tasks. Agents run in parallel in their own tabs. You watch live, or replay any session like a video.

  Website · Docs

Get started
  1. Install BrowserOS neo and import from Chrome in one click: logins, bookmarks, extensions.
  2. It finds your agents. Claude Code, Codex, Cursor, VS Code, OpenClaw, Hermes; connect with one click.
  3. Give it a task from your agent. "Book me the cheapest flight to London." Watch it live from your new tab, replay it later.

To be clear, BrowserOS neo is NOT a Chrome replacement. It's a secondary browser that sits next to Chrome, and we’ve made it agent friendly.

What can your agents do?

Anything that needs a logged-in browser:

  • Post content to your social media (LinkedIn, Twitter/X), queue posts, pull engagement numbers
  • Clear your inbox, unsubscribe from junk email
  • Update your CRM, file expenses, pull reports from internal tools

  • Your logins. Agents automate your real work using your logged-in accounts, not a blank sandbox. How it works
  • Parallel agents. Fire off several tasks at once. Each agent works in its own tab while you keep browsing.
  • Fewer tokens. For the same task, BrowserOS neo consumes significantly less tokens compare to other solutions (like Claude's chrome extension, Codex browser).
  • Local-only, privacy-first. Sessions, screenshots, and history live under ~/.browserclaw/ and never leave your machine. Privacy
Why BrowserOS neo over the alternatives?
  • Not a headless driver. Playwright and agent-browser spin up a fresh Chrome subprocess with no logins. Great for CI, useless for real work which requires your logged-in state like "read my inbox." BrowserOS neo imports your logins with one click and persists it across sessions.
  • Not a cloud browser. Cloud browsers (like browser-use, browserbase) run in a datacenter, so logging into your accounts is a pain, and sites like Twitter and LinkedIn block you because you are on a datacenter IP. BrowserOS neo runs on your machine, on 127.0.0.1.
  • Not a locked-in AI browser. Atlas, Comet, and Dia only work with their own AI. BrowserOS neo works with the agents you already use and pay for -- Claude Code, Cowork, Codex, Cursor, etc.

What is BrowserOS? BrowserOS is a free, open-source Chromium fork with an AI agent built into every new tab. Ask it to summarise a page, click through a flow, extract data, or run a scheduled task, and it uses 20+ built-in tools plus 40+ app integrations to get the work done. Bring your own AI keys or run everything locally with Ollama.

Every AI browser today asks you to sign into their cloud and hand over your data. BrowserOS is the one that doesn't. Same daily browser you already use, with a helpful agent one keystroke away.
