What it is

BrowserOS is an open-source Chromium-based browser with AI agents for carrying out web tasks from natural-language directions. The agents can navigate, click, type, fill forms, extract data, and run workflows across multiple steps. Chat Mode answers questions about the page in view; visual Graph Mode for repeatable workflows is marked as coming soon. BrowserOS supports Gemini, Claude, OpenAI, and local models through Ollama or LM Studio. Its maker lists more than 40 MCP app integrations, including Gmail, Slack, Notion, and Calendar, as well as 53 built-in browser tools. An included MCP server connects with Claude Code, Gemini CLI, or Codex. As a Chromium fork, it supports Chrome extensions and import of Chrome bookmarks, passwords, and settings. Browsing data stays on-device unless cloud syncing is enabled; syncing is off by default, and synced activity is encrypted on BrowserOS servers. BrowserOS says it does not store or log AI prompts or responses, though providers may handle submitted data under their own policies. It is free and licensed under AGPL-3.0.

Who it suits

BrowserOS suits people who want browser tasks handled through natural-language instructions, or developers who want an MCP server connection to coding assistants. It is also a fit for users who want Chrome extension support and local-model options, though local models are not yet powerful enough for Agent Mode.

BrowserOS in depth

Read the full write-up

BrowserOS is an open-source Chromium browser that turns natural-language requests into browser actions. It suits automation-minded users, developers, and Chrome users who want connected workflows without abandoning familiar extensions. The strongest case is its unusually broad agent and integration surface; the main caution is that serious Agent Mode currently requires cloud AI.

Overview

BrowserOS agents can click, type, navigate, fill forms, extract data, and execute multi-step web workflows. Chat Mode answers questions about the page currently open, making it useful for immediate research or page assistance. Visual Graph Mode, intended for repeatable workflows, is still coming soon, so this is better for on-demand automation than for organisations looking for a finished visual workflow builder.

It is a Chromium fork rather than a separate browser ecosystem. Chrome extensions work, and bookmarks, passwords, and settings can be imported, which makes switching less disruptive for existing Chrome users.

Key features

Agents and connections

BrowserOS supports Gemini, Claude, and OpenAI, with local-model connections through Ollama or LM Studio. More than 40 MCP app integrations include Gmail, Slack, Notion, and Calendar, while the product lists 53 built-in browser tools. That combination gives technically inclined users many ways to move information between web pages and other services, although cloud-provider API use can become a separate expense.

The built-in MCP server connects BrowserOS with Claude Code, Gemini CLI, or Codex. This makes it a credible companion for developers who want coding agents to trigger or coordinate browser work, rather than merely a browser with a chat panel.

Privacy and openness

BrowserOS says browsing data remains on the device unless cloud syncing is enabled. Sync is off by default; when enabled, activity is encrypted on BrowserOS servers. The maker also says it does not store or log AI prompts or responses, though the selected AI provider may process submitted data under its own policy. The AGPL-3.0 licence and public GitHub contribution path will appeal to users who prefer inspectable, modifiable software.

There is an important capability boundary: documentation says local LLMs are not yet powerful enough for Agent Mode. Local models can avoid provider charges, but they do not currently provide the full automation experience.

Pricing

Free

The Free plan costs nothing and includes open-source software, built-in AI agents, and operation on macOS, Windows, and Linux. It is the natural starting point for individuals evaluating the browser or running ordinary browsing and occasional automation.

BrowserOS

The BrowserOS plan also costs nothing and is billed Free. It is open source, but the default AI model has limited daily usage. Other cloud AI providers charge according to their API usage, while local models are free. In practice, the browser itself has no subscription price, but sustained agent use can be constrained by daily limits or shifted to provider billing.

There are no published seat allowances, trial period, renewal charge, or paid-team terms. Users choosing BrowserOS should therefore budget around their chosen AI provider rather than around a BrowserOS licence fee.

Platforms

BrowserOS runs on desktop macOS, Windows, and Linux, distributed as a browser extension and desktop software. Chromium compatibility brings Chrome Web Store extensions, while the desktop focus excludes mobile use from the stated platform support.

Who it's for

Choose BrowserOS if you want natural-language browser automation, MCP-connected applications, and developer-tool integration in one Chromium-based environment. It is particularly well matched to developers, power users, and privacy-conscious users who value local browsing storage and an AGPL-licensed codebase.

It is a weaker fit for users who need dependable local-model Agent Mode, a polished visual workflow designer today, or predictable all-inclusive AI costs. Those users may prefer a conventional browser or a service with clearer automation quotas.

Pros and cons

Pros

Broad automation surface: agents handle clicks, forms, extraction, navigation, and multi-step tasks.

Strong interoperability: 40-plus MCP integrations, 53 browser tools, and an MCP server for Claude Code, Gemini CLI, and Codex.

Low switching cost: Chrome extensions and imports for bookmarks, passwords, and settings preserve an existing Chrome setup.

Open and privacy-oriented: AGPL-3.0 licensing, on-device browsing by default, and encrypted optional sync.

Cons

Cloud dependence for full agents: local models are currently too weak for Agent Mode.

Variable AI cost: cloud providers may bill API usage, and the default model has limited daily use.

Incomplete workflow tooling: visual Graph Mode is not yet available.

Alternatives

Pick Gemini instead if you want a freemium assistant with web, desktop, and mobile access, plus image tools, Deep Research, Gemini Live, Canvas, and Gems.

Claude in Chrome is the better choice when browser-connected Claude chat, web search, file creation, code execution, memory, and tool connections matter more than an open-source Chromium fork.

Choose Comet for a free downloadable browser on Android, iOS, macOS, and Windows without an open-source base.

Muse suits readers seeking a freemium browser with periodically refreshed free usage and paid token plans.

Consider Genspark AI Browser for on-device free AI with 169 open-weight models and no subscription or usage limits.

Skyvern is an alternative for API, self-hosted, or web automation with credit-based plans and concurrent-run allowances.

Choose Strawberry Browser if macOS or Windows support and fixed monthly credit plans are your priority.

UseAgent is another free option for Linux, self-hosted, and web deployments.

Verdict

BrowserOS is best for technically capable users who want an open Chromium browser that can execute browser tasks and connect them to apps and coding agents. Its breadth, extension compatibility, and zero software price are compelling. Look elsewhere if local AI, finished visual workflow authoring, or a predictable bundled cost is more important than extensibility.

Verdict

BrowserOS combines a Chromium browser with task-oriented AI agents, integrations, and developer connections. The base product is free, but AI usage can have limits or provider charges, and local models have an Agent Mode limitation.
