Overview
About Playwriter
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.
About Prefactor
Prefactor is an innovative control plane tailored specifically for managing AI agents, addressing the critical need for robust security and governance in a rapidly evolving automated landscape. As organizations increasingly adopt AI technologies, ensuring secure access and compliance becomes paramount. Prefactor empowers enterprises by providing each AI agent with a first-class, auditable identity that facilitates secure access to essential tools and data. This capability is especially vital for industries with stringent regulatory requirements, such as banking, healthcare, and mining, where compliance is non-negotiable. By implementing features such as dynamic client registration, delegated access, and fine-grained role and attribute controls, Prefactor guarantees that every action taken by an AI agent is authenticated and monitored. Designed for scalability and compliance, the platform delivers SOC 2-ready security, seamlessly integrating with tools like LangChain and CrewAI. As organizations transition from proof of concept (POC) to production, Prefactor serves as a single source of truth, aligning security, product, engineering, and compliance teams around a comprehensive governance framework for AI agents.
