If your Hyperbrowser session keeps dying when your script disconnects, that is the default behavior - disconnecting over CDP stops the session. Append &keepAlive=true to the wsEndpoint when you connect and the session survives disconnects, living until its timeoutMinutes value or until you explicitly stop it. Useful for multi-step pipelines where your process reconnects later to the same browser.

Context: Hyperbrowser's official session lifecycle docs: when you disconnect from a session via Playwright or Puppeteer, the session automatically stops. To keep it alive across disconnects, add the &keepAlive=true query parameter to the session's WebSocket endpoint when connecting over CDP. The session then stays alive until its timeout (default team setting or the timeoutMinutes passed at creation) or until you stop it via the API.
