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 cutting-edge control plane engineered to manage AI agents efficiently at scale, particularly within regulated environments. It is designed for organizations that require stringent compliance and security measures. The platform empowers businesses to create auditable identities for each AI agent, facilitating dynamic client registration, delegated access, and detailed role and attribute controls. This is crucial for aligning security, engineering, product, and compliance efforts around a unified source of truth for AI agents. Prefactor seamlessly integrates with policy-as-code, allowing for automated permissions management within continuous integration and continuous deployment (CI/CD) pipelines, thereby providing complete visibility over agent actions. With SOC 2-ready security capabilities, Prefactor instills confidence in companies operating in highly regulated sectors. By transforming complex authentication processes into a streamlined governance framework, Prefactor enables organizations to effectively oversee their AI agents from initial proof of concept to full production deployment.
