When to use which
Use Pagerunner when
Privacy-sensitive workflows, individual developer automation, and anything involving real credentials you don't want in the cloud. When vendor independence matters.
Use Browserbase when
You need 10+ parallel browser sessions, team collaboration features, or enterprise SLA guarantees. When scale matters more than privacy.
