BrowserOS

BrowserOS is an open-source Chromium-based browser with built-in AI agent capabilities that can automate browser tasks via natural language. It supports both cloud LLM providers and local models, emphasizing privacy by keeping data local and offering MCP server integration.

What BrowserOS is

TypeScript/Go monorepo combining a Chromium fork with an agent platform exposing 53+ Model Context Protocol tools for browser automation. Runs as a desktop app (macOS, Windows, Linux) with a Bun-based MCP server, browser extension UI, and Go CLI for remote control.

Quickstart

Get the BrowserOS source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/browseros-ai/BrowserOS.gitcd BrowserOS# follow the project's README for install & configuration

Best use cases

Autonomous Web Research & Data Extraction

Delegate repetitive browsing tasks—scraping data, comparing prices, gathering competitive intelligence—to AI agents without manual intervention. Scheduled task support enables unattended execution.

Privacy-Conscious AI-Assisted Workflows

Users who require full data privacy can run BrowserOS with local LLMs (Ollama, LM Studio) or bring their own API keys, ensuring no third-party telemetry or data leakage beyond their control.

MCP-Native Integration Hub

Organizations standardizing on Model Context Protocol can embed BrowserOS as an MCP server within Claude Code, Gemini CLI, or custom agents, unifying file operations and web automation in one tool.

Implementation considerations

  • Chromium fork maintenance burden: track upstream Chromium patches and security updates to avoid accumulating technical debt; review `chromium_patches/` regularly.
  • Local LLM setup complexity: Ollama or LM Studio installation and tuning is optional but required for offline privacy; cloud provider API keys (OpenAI, Anthropic, etc.) must be injected and securely stored.
  • Agent reliability variability: 53 browser automation tools depend on DOM structure stability; websites with heavy JavaScript rendering may require custom selectors or agent prompt tuning.
  • Disk footprint: Chromium build is large; AppImage, .dmg, and .exe installers each require separate distribution and update channels.
  • Data migration: Chrome bookmarks/password import works but requires user action; automated migration for existing browser profiles is not clearly documented.

When to avoid it — and what to weigh

  • Need Proprietary SLA/Support — BrowserOS is community-driven with no commercial support contract, SLA, or vendor backing. Unsuitable for mission-critical deployments requiring guaranteed response times.
  • Require Manifest V3 Ad-Blocking Only — The project explicitly supports Manifest V2 add-ons (uBlock Origin). If your compliance or extension strategy mandates MV3-only architecture, this may create friction.
  • Cannot Accept AGPL Copyleft Terms — AGPL-3.0 requires any network-served modifications to release source under the same license. Closed proprietary forks or SaaS offerings without source disclosure are legally incompatible.
  • Need Audited Security in Regulated Domains — No security audit, pen test results, or formal threat model are documented. Healthcare, finance, or other regulated sectors will require independent evaluation before deployment.

License & commercial use

AGPL-3.0 (GNU Affero General Public License v3.0). Copyleft license requiring all derivative works or network-accessible modifications to release source code under the same license. Pure open-source projects may use it freely; proprietary or SaaS forks require source disclosure.

AGPL-3.0 is permissive for internal commercial use (running the unmodified software), but commercial forks or SaaS offerings must open-source any modifications and disclose source to users. Requires legal review if packaging BrowserOS as a managed service or integrating into proprietary products. No commercial support, warranty, or licensing terms from the project.

Security considerations

No public security audit or formal threat model disclosed. Chromium fork inherits browser security model but custom patches may introduce vulnerabilities; critical to track upstream Chromium security releases. Local-first architecture minimizes data exfiltration risk if using local LLMs. API key handling (OAuth, cloud credentials) should assume keys can be exfiltrated via malicious agents or extensions; recommend external secrets management. MCP server exposure to untrusted agents could enable lateral movement to local files or system commands.

Alternatives to consider

Claude Cowork (Anthropic)

Natively integrates file operations and web search via Claude's first-party infrastructure; no installation required, but closed-source and limited browser automation compared to BrowserOS.

Chrome DevTools Protocol + Custom Automation (e.g., Playwright, Puppeteer)

Lightweight, well-documented open-source libraries for browser automation; no AI agent UI, so requires custom orchestration and LLM integration, but maximum flexibility and no new runtime.

OpenClaw (open-source agentic browser, early-stage)

Comparable feature set and open-source principles, but earlier in maturity (unclear release frequency, smaller community); referenced in BrowserOS comparisons as a direct alternative.

BrowserOS FAQ

Can I use BrowserOS for commercial SaaS without open-sourcing modifications?
No. AGPL-3.0 requires any network-accessible version to release source code. A managed SaaS offering would need to open-source your modifications or negotiate a separate commercial license (not offered by the project).
Does BrowserOS work with local LLMs, or do I need a cloud provider?
Both. It supports local models via Ollama or LM Studio for full privacy, plus cloud providers (OpenAI, Anthropic, Google, Qwen, etc.) via API keys or OAuth. Your choice; no vendor lock-in.
How do I run agents programmatically or integrate with my CI/CD pipeline?
Use the Go CLI (`browseros-cli`) to launch and control BrowserOS from the terminal, or integrate via the MCP server for use within Claude Code or custom agents. SDK support (agent-sdk package) exists but requires review of package docs.
Is BrowserOS suitable for handling sensitive data (PII, healthcare, finance)?
Requires careful evaluation. No security audit or compliance certifications are documented. Local-first architecture helps, but security review and formal threat modeling are recommended before handling regulated data.
