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 essential control plane for AI agents, designed to solve the critical governance gap that emerges when organizations transition autonomous agents from proof-of-concept to full-scale production. It provides a centralized platform for managing identity, access, and auditability across all AI agents within an enterprise. Built specifically for product and engineering teams in regulated industries like banking, healthcare, and mining, Prefactor addresses the core challenges of security, compliance, and operational visibility that typically block safe agent deployment at scale. Its main value proposition is transforming complex, ad-hoc agent authentication and monitoring into a single, elegant layer of trust. By assigning every AI agent a first-class, auditable identity and enabling policy-as-code management, Prefactor aligns security, product, engineering, and compliance teams around one unified source of truth. This allows companies to govern their AI agent fleets faster with shared visibility and control, ensuring agents can operate safely and reliably in environments where "move fast and break things" is not an option.
