documented capabilities
CDP / WebSocket- Custom proxies
- Supports custom HTTP/HTTPS proxies, built-in residential proxies and domain-based routing rules.[1]
- Location behavior
- Built-in proxy geolocation is best effort; the closest available location may be used.[1]
- Billing increments
- Browser time is billed by the minute and proxy traffic by the MB, with a one-minute and one-MB minimum per session.[2]
- Concurrency
- Current published limits are 3 sessions on Free, 25 on Developer and 100 on Startup.[2]
- Reconnection
- A timeout extends duration but a normal session ends on disconnect; keepAlive enables reconnection.[3]
Billing: Browser time plus built-in proxy traffic, with plan allowances and overages.
Outputs: browser-session
Documented for: Playwright, Puppeteer, Selenium

- Enable keepAlive when reconnecting is required; release completed sessions.
Requirements & limitations
- Proxy access starts on a paid plan; plan allocations and overage rates differ.
- Session creation rate is a separate limit from concurrent running sessions.
- Country and city selection are not strict availability guarantees.
