history

Project history and usage

BrowserOS is an open-source Chromium-based browser with a built-in AI agent. It supports hosted or local models and exposes browser automation to compatible external agents through MCP.

Project history

BrowserOS emerged in 2025 as an open-source Chromium fork with a built-in AI agent. The project credits Chromium and ungoogled-chromium as its browser foundations.

The original BrowserOS product is a browser operated by a person with an agent built into each new tab. The same project later introduced BrowserOS neo, a companion browser designed to be driven by external AI tools.

Development added provider choice, local Ollama and LM Studio support, scheduled tasks, MCP integrations, cloud-sync options, and controlled local file and command access.

Adoption history

BrowserOS is distributed as a desktop Chromium fork for macOS, Windows, and Linux and is designed to retain compatibility with familiar browser data and Chrome extensions.

The project broadened from an AI-assisted browser for human users into a repository that also houses BrowserOS neo, a secondary browser intended for external MCP agents.

How it is used

Users can browse normally while asking the built-in agent to navigate sites, fill forms, extract information, and perform multi-step web tasks.

Users may bring API access for supported model providers or run local models through Ollama or LM Studio. BrowserOS can also act as an MCP server for tools such as Claude Code and other compatible clients.

The application stores browser profiles and provider state locally, but the official user documentation reviewed does not identify stable individual config or credentials files, so no file paths are asserted.

Why package nerds care

BrowserOS is notable to package users because it combines a complete Chromium-derived browser with a locally running agent service rather than shipping only a browser extension or hosted automation API.

Its bring-your-own-model design, local-model support, MCP endpoint, and AGPL licensing make it relevant to users seeking inspectable, locally controlled browser automation.

security posture

No protected-tool coverage found yet

No matching local secret-handling manifest was found for browseros. Package metadata is still published here so future coverage has a stable package URL.

Install behavior

  • No Homebrew post-install hook is recorded in formula metadata.
  • No Homebrew bottle metadata was recorded.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
