Scalebrowser is self-hosted browser infrastructure for developers and teams that need AI agents to do more than open a page. It runs a patched Chromium engine on your hardware and gives every agent an isolated browser profile with a persistent identity. The same profile comes back with the same cookies, passkeys, stored logins, memory, tasks, and device identity after a restart, an update, or an encrypted move to another machine you control.
That persistence matters because browser automation usually fails before useful work begins. A site spots the control layer, the identity changes between sessions, a login code lands somewhere the agent cannot reach, a captcha blocks the flow, or a browser permission bubble sits outside the page. Scalebrowser addresses those layers together. It checks connection and fingerprint coherence, uses the real GPU and screen in the machine, removes automation traces inside the browser engine, and routes clicks, typing, and scrolling through a human-like input layer.
Each profile can hold encrypted credentials without exposing their values to the agent. Passkeys survive browser shutdowns. Email and SMS verification codes arrive through the profile, TOTP is generated locally, and 18 captcha types have been measured as solved on live widgets. Browser-level permission prompts and device pickers are exposed to the agent instead of becoming invisible blockers.
The agent interface is designed to preserve context. Scalebrowser exposes 21 tools by default from a catalog of 62, sends a compact map of interactive page elements, and returns only what changed after the first read. Stale references fail clearly instead of clicking the wrong element. Every run starts with an intent, records each step with a screenshot, and can enforce read-only mode and address rules. Secrets found on a page are replaced with stable placeholders before they reach the model.
Connect through MCP, the REST API, Node.js, Python, or direct CDP. Group, reserve, start, stop, and assign proxies or extensions across many profiles at once. Record ordinary work as reusable recipes. Turn a completed run into a polished video with automatic camera movement, cursor motion, voiceover, subtitles, and channel-ready exports, or render it as an unbroken proof record.
Every paid plan includes the full product and unlimited profiles. You pay only for how many browsers run at once and how many machines can be connected. Plans start at €19 per month, with a seven-day trial.
