Scalebrowser

Scalebrowser is browser infrastructure built for AI agents, giving every agent isolated browser profiles with persistent identities. Each profile comes with stored logins, passkeys, cookies, two-factor authentication, captcha handling, and full browser automation, so agents can work through real websites without hitting the usual walls.

Connecting is flexible: agents can plug in through MCP, the Python or Node SDKs, REST, or a direct CDP connection. Meanwhile, credentials stay encrypted on the user's machine, so sensitive login data never has to leave the user's control.

Because each profile preserves its identity across restarts, agents stay signed in session after session. That makes it easy to operate websites repeatedly and reliably, at a scale that manual browsing could never match.
