Open Browser Use
An open-source toolkit that hands an AI agent a real Chrome browser, with browser control split from swappable skill documents.
Pick Open Browser Use if you would rather read the entire browser-control loop before pointing it at a live site — a 0.1.0-alpha2 tree of 11 directories and 7 files is auditable in an afternoon, and the windowId plus sessionId model makes multi-tab agent work traceable. Skills shipped as documents under docs/capabilities mean you extend behaviour without forking the execution client. Walk away if you need a supported release or an SLA: this is a reference implementation, not a service, and you become the maintainer. Teams that want a managed browser-agent platform should look at hosted alternatives instead.

Skip Open Browser Use if you need a supported release with an SLA and a managed runtime — at 0.1.0-alpha2 with 11 directories and 7 files, you take on the maintenance yourself.
You supply the runtime: there is no cloud execution layer, so the compute, Chrome processes and operational time all come out of your own budget.
Open Browser Use is published free as an open-source toolkit at version 0.1.0-alpha2, with no per-run fees and no cloud runtime to bill for. That places it below paid hosted browser-agent platforms on cash cost and above them on engineering time: you save the subscription and spend the hours self-hosting, forking and maintaining the loop yourself.

Open Browser Use is an open-source toolkit for driving a real Chrome browser from an AI agent. The author built it after pulling apart the Browser Use capability OpenAI shipped inside Codex.app, then reimplementing the useful parts in a platform-neutral package that follows his earlier Open-Computer-Use release. Published at version 0.1.0-alpha2 with a tree of 11 directories and 7 files: a browser-client.mjs execution client, a SKILL.md declaration, an openai.yaml agent definition, and capability documents under docs/capabilities covering viewport and visibility. It sits on Chromium's multi-process design, so each tab gets its own Renderer Process under Site Isolation and one crashed tab does not take the session down, while Renderer Process sandboxing limits what page code can reach. Agent state is addressed by windowId plus sessionId, so one browser window maps to one agent session and multi-tab work stays trackable. The example loop keeps a stateful context open across steps: navigate, wait for domcontentloaded, snapshot the DOM, filter the lines you care about. Capabilities live as documents separate from the client that executes them, so adding behaviour means writing a capability doc rather than patching a monolith. Python and Node.js SDKs ship with it, headed and headless modes both work, and Service Worker support matters once you touch v3 extensions. The article also compares Codex's two paths, IAB (the in-app browser) and Chrome via the browser extension, which is where the abstracted browser-client.mjs hides the difference from callers. Compared with hosted browser-agent platforms, you trade onboarding and support for full ownership of the loop. It is a reference implementation, not a supported release — expect to be the maintainer of anything you build on it.
Key features
- Drives a real Chrome browser instead of a simulated page
- browser-client.mjs execution client separated from skill definitions
- SKILL.md skill declarations
- Capability documents under docs/capabilities (viewport, visibility, tab)
- openai.yaml agent definition
- Chromium multi-process model with Site Isolation per tab
- Renderer Process sandboxing to restrict page code access
- Agent state addressed by windowId plus sessionId
- One browser window maps to one agent session
- Multi-tab session management
- Stateful context held open across steps: navigate, wait for domcontentloaded, DOM snapshot and filter
- Python SDK
- Node.js SDK
- Headed and headless Chrome operation
- Service Worker support for v3 browser extensions
Behind the verdict
The interesting decision here is architectural, not feature-count. Open Browser Use keeps browser-client.mjs, the thing that actually executes, separate from SKILL.md and the capability documents under docs/capabilities (viewport.md, visibility.md, tab). Adding behaviour is a documentation exercise, not a refactor of a monolith. That is the right split for a project this young, and it is the piece most tools in this category get wrong. The second strength is that it drives a real Chrome rather than a simulated page. Because Chromium isolates tabs into separate Renderer Processes, a single crashed tab does not end the session, and Renderer Process sandboxing limits what page code can reach. State addressed by windowId plus sessionId gives you one browser window per agent session, so a multi-tab extraction run stays trackable instead of devolving into element re-location on every turn. The documented loop — navigate, wait for domcontentloaded, snapshot the DOM, filter — is deliberately boring, and boring is what you want in automation you own. Where it is weak: version 0.1.0-alpha2 with a file tree of 11 directories and 7 files is a readable reference, not a supported release. There is no cloud runtime to fall back on, so you need real programming ability and a willingness to self-host. The author wrote the surrounding article in Chinese and states plainly that the English version was AI-translated for him, so parts of the explanation read as translation. The scoped tree he walks through covers browser control and skill extensibility and does not describe a specific AI model integration — you bring your own agent. Where it fits: Python and Node.js developers wiring click, type, scroll and screenshot actions into an LLM agent they already run, researchers studying how Codex.app-style Browser Use and IAB are implemented, and anyone who wants the loop auditable before trusting it with a live session. Where it does not: non-technical buyers, teams that need an SLA, and anyone who wants published integrations with common SaaS tools out of the box. Compared with hosted browser-agent platforms you trade onboarding support for ownership, which is the whole point.
Limitations
- Version 0.1.0-alpha2, with a file tree of 11 directories and 7 files — this is an early, readable reference implementation, not a supported release.
- You need real programming ability and a willingness to self-host; there is no cloud runtime to fall back on.
- The author's original write-up is in Chinese and he states plainly that the English version was AI-translated for him, so some of the surrounding explanation reads as translation.
- The scoped tree he walks through — SKILL.md, browser-client.mjs, docs/capabilities, an openai.yaml agent definition — covers browser control and skill extensibility, and does not describe a specific AI model integration.
- Expect to be the maintainer of anything you build on it.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Open Browser Use actually fits — and what changes day-one when you adopt it.
You wrap browser-client.mjs with the Python SDK, open a stateful context, navigate to the portal, wait for domcontentloaded, snapshot the DOM and filter the rows you need before clicking through to the export.
Outcome: A repeatable script that drives real Chrome, with the session addressed by windowId plus sessionId so you can find the right window on later turns.
Instead of patching the execution client, you write a capability document under docs/capabilities describing the behaviour, and declare it through SKILL.md alongside the openai.yaml agent definition.
Outcome: Browser actions become a swappable skill, and the browser-client.mjs layer keeps hiding whether the request came from the in-app browser path or the extension path.
Use cases
- Wire browser actions — click, type, scroll, screenshot — into an LLM agent you already run
- Automate multi-tab web data extraction
- Script form filling and multi-step navigation as an agent skill
- Drive a real Chrome session for testing instead of a simulation
- Fork the browser-control loop and add your own capability documents
- Study how Codex.app-style in-app browser and extension Browser Use is implemented
Setup time & first value
How long it actually takes to get something useful out of Open Browser Use — broken out by persona, not the marketing-page minute.
For a Python or Node.js developer, cloning the repository and getting a headed Chrome session to complete a navigate-and-snapshot loop is an afternoon's work; reading the 11-directory, 7-file tree end to end adds a few more hours. Non-technical buyers should not start — there is no installer path.
Switching to or from Open Browser Use
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a hosted browser-agent platform: port your step list into a capability document and call browser-client.mjs locally instead of the hosted endpoint.
- →From hand-rolled Selenium or Playwright scripts: keep the step logic, replace the driver with the browser-client.mjs execution client and its windowId plus sessionId state model.
- →From Codex.app bundled Browser Use: take the 0.1.0-alpha2 tree you were already reading and switch to the platform-neutral package.
- ↗To a managed browser-agent service: move your capability documents back into that vendor's action schema and give up local Chrome process control.
- ↗To a full test framework: rebuild your flows as Playwright or Selenium suites if you need a supported release and CI tooling rather than an agent-facing client.
- ↗To writing your own client: keep SKILL.md and docs/capabilities, replace browser-client.mjs with your own driver.
