About AntiBrow

We build a browser that keeps each identity intact - and keeps that identity on your machine.

What we build

AntiBrow is an antidetect browser for people who run many identities at once - and for the AI agents that increasingly run them on their behalf. Each profile gets a coherent, real-device fingerprint applied in the browser engine itself, keeps its own cookies, storage and passkeys, and can be driven either from a desktop window or from the standard Playwright API.

The design constraint we hold ourselves to: configuring an identity is our API, but operating the browser is not. Once a profile is open you are back on plain Playwright, with nothing proprietary to learn and nothing to unlearn if you leave.

What we hold to

1

Your profiles live on your disk

Profiles, cookies, storage and passkeys are written to your own machine. Cloud sync is a feature you switch on per profile, not a condition of using the product. Nothing is uploaded from a profile that has sync turned off. Read the data boundary →

2

Claims you can check yourself

We publish the detector runs we make, on public checks anyone can repeat - not a badge that says "undetectable". Detection is an arms race, results move, and we would rather show a dated run than a permanent promise.

3

No lock-in by construction

Profiles export to a portable archive you keep. Automation runs on the standard Playwright API. If you stop paying us, your local profiles keep working, and if you leave entirely you take your data with you.

4

Free tier that is actually usable

Unlimited local profiles, no card, no expiry. We charge for concurrency, cloud sync, managed proxies and Live View - not for the right to create another identity.

Who it's for

Agent & automation developers
You already write Playwright, and you're tired of maintaining a stealth patch stack that breaks every release.
Multi-account operators
You run dozens of identities by hand and need each one to stay warm, isolated and recognisably itself.
Teams with a data policy
You cannot hand session cookies to a vendor's cloud, so a local-first tool is the only kind you're allowed to adopt.

Talk to us

AntiBrow is built by a small independent team. We answer support directly - there is no tier of the product where a human stops replying. Questions about the data boundary, licensing or a detection result you can't reproduce all go to the same place: contact us.
