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

Alright, let's get real. AI agents are the rockstars of the demo world, looking like geniuses in a controlled slideshow. But the second you try to unleash them in your actual company? Chaos. Absolute chaos. Your security team is having a meltdown, compliance is asking for logs that don't exist, and you're basically letting a bunch of anonymous, unaccountable bots loose in your digital HQ. That's the dumpster fire Prefactor puts out. Think of it as the ultimate bouncer and control room for your AI agent army. It's the missing layer of trust that turns your scary, ungoverned agent sprawl from a sketchy proof-of-concept into a legit, production-ready system. Prefactor gives every single agent a proper, auditable identity (no more shady anonymous API calls), lets you see everything they're doing in real-time, and gives you crazy granular control over who can do what. Built for the big leagues—think finance, healthcare, mining—where "move fast and break things" is a one-way ticket to getting fired. It's the control plane that finally lets engineering, product, and security all chill out while your agents actually get useful work done without burning the house down.
