The open-source Browser Use Cloud alternative
Describe a job in your own words. It drives a real browser and hands back structured data, on hardware you own.

OpenBrowse serves the same v3 REST surface that browser-use-sdk already speaks. Point the client at your own box and everything downstream stays put.
import { BrowserUse } from "browser-use-sdk/v3"; const client = new BrowserUse({- apiKey: process.env.BROWSER_USE_API_KEY,+ apiKey: process.env.OPENBROWSE_API_KEY,+ baseUrl: "https://your-host/v3", });Cheaper, faster, hallucination-resistant.
The same result for a fraction of the spend, in less time, with nothing in it the page did not say. Our extraction benchmark measures all three.

What it does that a cloud runner does not
Real tabs, not just code.
The agent drives real tabs the way a person would, opening a whole listing in parallel waves of six and reading inside panels served from another domain.
Data completeness, guaranteed.
Every write is checked against your schema as it discovers data, with coverage tracked field by field.
Separate "missing" from "failed".
Values with no evidence on the page are refused at the boundary, so you genuinely know if something's not there to see.

Drop into any session for a live view of the browser, the model's reasoning as it arrives, and the sandbox scripts it writes streaming in.
FAQs
What is OpenBrowse?
A free, self-hosted alternative to Browser Use Cloud. Describe a job, an AI agent drives a real browser on hardware you own, and you get structured data back.
How does it compare to Browser Use Cloud?
Same v3 API, your hardware, your network, no per-task/platform/proxy fees. OpenBrowse does not currently support BU's v4 API though, nor does it have BU Cloud's recordings or workspaces features.
Full comparisonWhat does it cost to run?
Just LLM tokens: no platform fee, and maxCostUsd hard-caps any session. Our benchmark job cost $0.24 here against $0.78 on the cloud, though that pair changes model as well as runtime. Holding the model steady, claude-sonnet-5 at reasoning high cost $0.40 here against $0.78 there.
See the benchmarkHow do I migrate from Browser Use Cloud?
Change two lines: your apiKey and your baseUrl. Everything downstream carries over untouched.
Migration guideCan I bring my existing profiles?
Yes. Import your cloud profile export and existing profileId references keep working. Concurrent sessions can safely share that profile: each merges only its own cookie and storage changes back when it finishes.
ProfilesWhich model should I use?
Whichever suits the job. Worth knowing: OpenAI models do better with less reasoning, Anthropic's with more.
Choosing a modelDoes it solve CAPTCHAs?
Optionally, with your own CapSolver key. Most common types are solved; the rest are named rather than silently attempted.
Solving CAPTCHAsDoes it work with the Browser Use v4 API?
Not yet. OpenBrowse implements v3; v4 support is planned.
Is OpenBrowse affiliated with Browser Use, and how is it licensed?
No, it is independent, and built on Browser Use's own open-source SDK. MIT licensed, with a DOI so it can be cited.
How is this different from Firecrawl?
Firecrawl is a crawler: give it URLs, get clean page content back. OpenBrowse is an agent: give it an outcome and it works the site out for itself.
How does it compare to Browserbase?
Browserbase rents you a browser to drive. OpenBrowse is the driver, on your own hardware. No connect endpoint, so existing automation is a rewrite.
