BrowserOS (ex-Nxtscape): open-source agentic browser draws 13.5k GitHub stars
Open-source, local-first agentic browser launched on HN as Nxtscape in 2025, now two shipping products and 13.5k GitHub stars as BrowserOS.
BrowserOS (formerly Nxtscape)
What the business is
An AGPL-3.0 open-source Chromium fork with an AI agent platform, shipping BrowserOS (a human browser with an agent in the new tab) and BrowserOS neo (a second browser that AI agents drive), both local-first with imported Chrome logins and MCP connections.
How it started
Nithin Sonti, Nikhil Sonti and the BrowserOS team showed Nxtscape ('next-scape') on Hacker News on 2025-06-20 as an open-source, agentic browser for the AI era, built from San Francisco. The repo (github.com/nxtscape/nxtscape, now browseros-ai/BrowserOS) is AGPL-3.0 licensed and carries a Felafax, Inc. copyright, with the brothers named as authors in its citation.
What happened
The monorepo grew into two products: BrowserOS, a Chromium fork with an agent built into every new tab (20+ built-in tools, 40+ app integrations, bring-your-own AI keys or local Ollama, real uBlock Origin MV2 ad blocking, MCP server), and BrowserOS neo, a 'second browser for your agents' that imports Chrome logins, runs agents in parallel tabs, and records every session as a scrubbable video under ~/.browserclaw. The README positions both against Playwright-style headless drivers (no logins), cloud browsers like browser-use and browserbase (datacenter IPs blocked by sites), and locked-in AI browsers like Atlas, Comet and Dia.
How it ended up
Still live and expanding as of 2026-09-05: 3,785 commits, 13.5k stars and 1.4k forks on GitHub, with BrowserOS and BrowserOS neo shipping from the same monorepo; no funding round, revenue or user count is disclosed in the material.
Background
BrowserOS is an AGPL-3.0 open-source agentic browser — a Chromium fork plus an agent platform — whose bet is that real AI web work happens in a local, logged-in browser on the user's own machine, not in a headless sandbox, a datacenter cloud browser, or a browser locked to one company's model. It launched on Hacker News in June 2025 as Nxtscape, and the repo now ships two products: BrowserOS for humans and BrowserOS neo for their agents.
BrowserOS puts an agent in the human browser's new tab with 20+ built-in tools and 40+ app integrations, bring-your-own AI keys or local Ollama, and real ad blocking. BrowserOS neo is a separate 'second browser for your agents': logins, bookmarks and extensions import from Chrome in one click, agents such as Claude Code and Codex connect over MCP, run in parallel tabs, and every session is saved locally as a scrubbable video with an action timeline. Sessions, screenshots and history live under ~/.browserclaw and never leave the machine.
The README argues against each incumbent shape: Playwright-style drivers spin up fresh browsers with no logins, cloud browsers run on datacenter IPs that Twitter and LinkedIn block, and Atlas, Comet and Dia only work with their own AI. The 2025-06-20 Show HN drew 314 points and 206 comments, and by the 2026-09-05 fetch the repo carried 13.5k stars, 1.4k forks and 3,785 commits, with a Felafax, Inc. copyright and Nithin and Nikhil Sonti credited as authors.
What has to be true
- It attacked three incumbent shapes — headless drivers without logins, datacenter-cloud browsers, single-model AI browsers — by offering what none had: a logged-in, local browser agents can drive.
- Open source plus bring-your-own keys made privacy the moat: sessions, screenshots and history never upload, a claim cloud rivals structurally cannot match, and AGPL kept the code inspectable.
- Splitting the human browser (BrowserOS) from the agent browser (BrowserOS neo) in one monorepo gave each a clear job instead of one confused hybrid, and let agents integrate over MCP.
- It rode the open MCP standard instead of a proprietary agent channel, so Claude Code, Codex, Cursor and any MCP client connect in one click — distribution through tools devs already run.
What can be applied
Against cloud AI browsers, the winning stance is open source, local-first, BYO model — users trust their own machine with their logins more than a datacenter.
Aftermath
As of 2026-09-05 BrowserOS remains an active open-source project (AGPL-3.0) shipping BrowserOS and BrowserOS neo from a monorepo containing a Chromium fork plus a Rust/TypeScript/Go agent platform: 3,785 commits, 13.5k stars and 1.4k forks. neo runs on macOS and Windows; BrowserOS adds Linux. Sessions, screenshots and history stay under ~/.browserclaw and never upload, with anonymous usage events off by one toggle. No funding, revenue, user or download figures are disclosed in the material.
