Playwriter vs Prefactor

AI agents cannot browse the web properly. They either have no browser access, or they get a fresh Chrome with no logins, no extensions, and instant bot detection. Playwriter gives them your actual browser session instead. One Chrome extension, full automation API, everything you are already logged into. Includes accessibility snapshots (5-20KB instead of 100KB+ screenshots), a debugger with breakpoints, live code editing, network interception, and video recording. Works with any MCP client: Cursor, Claude, VS Code, and more. Open source, MIT licensed.

Prefactor is a revolutionary control plane specifically designed for managing AI agents, providing essential tools for identity, access, and compliance management. As organizations increasingly adopt AI technologies, they face challenges in ensuring that these agents operate securely and efficiently. Prefactor addresses these challenges with innovative features such as dynamic client registration, delegated access, and fine-grained control over roles and attributes. This ensures that every AI agent possesses a robust, auditable identity. The platform is ideal for product and engineering teams in highly regulated industries like banking, healthcare, and mining, where compliance and security are critical. By leveraging policy-as-code and automating permissions in CI/CD pipelines, Prefactor enables teams to govern AI agents at scale while maintaining full visibility into agent actions. Engineered for scalability, security, and interoperability, Prefactor transforms the complex landscape of agent authentication into a seamless trust layer.
