Capium FAQ
Short answers to the questions we hear most. If yours is not here, reach us through capzy.ai.
Do I need Patchright or a patched Playwright driver?
No. Capium is driven by stock Playwright. The stealth lives in the binary, so there is no patched driver to maintain.
How is this different from injecting stealth scripts?
The fingerprint surfaces are rewritten in Chromium's own source, not shimmed in JavaScript at runtime. There is no property being re-defined for a detector to catch.
Does the same seed always give the same device?
Yes. A seed deterministically derives the whole device, so re-using it reproduces the identity exactly. See Seeds & personas.
Which platforms can I run on?
Linux, Windows and macOS (Apple Silicon), including headless Linux servers. A Windows persona that uses Windows font metrics needs real Windows fonts on the host.
How does billing work?
Capium is licensed per concurrent session, not per gigabyte. Plans and billing are handled on capzy.ai. Each live browser is one concurrency slot.
Can I use my own proxies?
Yes. Capium runs locally and uses your egress by default. Pass any proxy you control, and use geoip to align WebRTC IP, timezone and geolocation to the exit.
Is there an async API?
Yes. Every entry point has an await-able twin: launch_async, launch_context_async and launch_persistent_context_async. See Async & persistent sessions.
