BrowserOS is an open-source, privacy-first Chromium fork (a standalone desktop browser, not an extension) with built-in AI agents that automate web tasks from natural-language prompts: clicking, typing, navigating, reading local files, and running multi-step workflows. It ships 53 built-in browser automation tools and 40+ app integrations (Gmail, Slack, Notion, Calendar) via MCP, plus scheduled tasks and a CLI to drive the browser from coding agents like Claude Code. Users bring their own provider API keys and switch between providers anytime; a default model with limited daily usage is included for testing, and local models run free via Ollama / LM Studio. Positioned as a privacy-first alternative to ChatGPT Atlas, Perplexity Comet, and Dia. Built by a YC-backed team (founded 2024, San Francisco). Licensed AGPL-3.0; available on macOS, Windows, and Linux.

Why this trust score (85/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

  • Key Safety 23/25: The key is held on your own device.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under AGPL-3.0, so anyone can check how the key is handled.
  • Privacy 14/15: Local-first: it works without sending your data anywhere. Can be self-hosted, so the data path stays inside infrastructure you control.
  • Maintenance 10/10: Actively developed: commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

What was checked

Verification tier RESEARCH_ASSISTED, derived from the evidence below and not set by hand.

  • [REPORTED · RESEARCH] This listing was compiled by an AI-assisted research pass over the tool's public website, README and documentation. No person independently confirmed it.
  • [STRONG · SOURCE_SCAN] Supports a local model backend, so it can run with no cloud provider key at all. source
  • [CONFIRMED · SOURCE_SCAN] Most recent commit 2026-08-15, about 0 month(s) ago. source

How your API key is handled

Your API key is stored locally on your device. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Open settings, paste your provider API key, choose a model, and start. The key stays on your device.
