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 the definitive control plane for AI agents, engineered to bridge the critical governance gap that emerges when autonomous systems transition from experimental proofs-of-concept to governed, production-ready assets. It provides the essential layer of trust and operational integrity required by SaaS companies and regulated enterprises in sectors like finance, healthcare, and mining. The platform addresses a fundamental challenge: while AI agents excel in demos, they often fail in production due to a lack of visibility, control, and auditability. Prefactor solves this by bestowing every AI agent with a first-class, auditable identity, applying the rigorous principles of human identity and access management to the autonomous software layer. By offering dynamic client registration, delegated access, and fine-grained policy controls, it creates a single, elegant source of truth. This enables security, product, engineering, and compliance teams to align, providing shared visibility, control, and compliance-ready audit trails. Built with scalability and stringent standards in mind, Prefactor delivers SOC 2-ready security, human-delegated oversight, and interoperable OAuth/OIDC support, empowering organizations to deploy AI agents with confidence.
