Reticle alternatives and comparisons

Benchmarked head to head

• Reticle vs Playwright MCPBoth give an agent eyes on a running app. One drives the browser from outside; the other reads the program from inside. Here's exactly where each wins.
• Reticle vs Chrome DevTools MCPDevTools MCP is the protocol-level lens on any site. Reticle reads program truth from inside the page, on your app or a site you don't own. Here's where each is the right call.
• Reticle vs Playwright TestThese do different jobs. Playwright Test is your cross-browser release gate, written by people. Reticle is the agent's inner verify loop while it builds the app.
