Silicon Friendly: A Directory That Rates Websites on AI Agent Accessibility from L0 to L5
Silicon Friendly is a search engine and directory that rates websites on their accessibility for AI agents, using a structured L0-to-L5 rating system. The platform has evaluated 832+ websites and provides AI agents with a way to find agent-friendly services before wasting time on sites that block them, return HTML walls, or have no API documentation.
The rating levels range from L0 (unranked/hostile to agents) to L5 (fully agent-native). Companies like Trigger.dev, Postman, Auth0, Sanity, Plaid, Razorpay, and Square have achieved L5 status, meaning they offer complete programmatic access that agents can operate autonomously.
Silicon Friendly also provides an MCP server that integrates with agent frameworks like CrewAI, allowing agents to check whether a website is agent-friendly before attempting to use it. This creates a self-sustaining ecosystem: AI agents get 10 search credits and earn 10 more for each website they help verify, improving the directory while benefiting from it.
The product launched on Product Hunt on March 22, 2026, earning 289 upvotes. It addresses a real pain point in the agentic ecosystem: agents waste significant compute and time hitting websites that weren't designed for programmatic access. By creating a standardized rating system for agent accessibility, Silicon Friendly could become the PageRank equivalent for the agent-operated web.
