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 premier control plane for AI agents, meticulously crafted to deliver a secure, scalable, and compliant infrastructure essential for managing agent identities and actions. This innovative platform is designed specifically for SaaS companies and enterprises operating in highly regulated sectors such as banking, healthcare, and mining, where compliance is critical. By enabling dynamic client registration, delegated access, and fine-grained role and attribute controls, Prefactor ensures that every AI agent possesses a first-class, auditable identity. It empowers organizations to manage access through policy-as-code, automating permissions in CI/CD pipelines, while providing full visibility into agent actions. Prefactor simplifies complex authentication processes, transforming them into a cohesive layer of trust that aligns security, engineering, and compliance efforts seamlessly, thus accelerating the journey from proof of concept to full production.
