Co-founder here. One thing oatcake didn't mention -- the MCP server actually learns what you build with over time. It tracks category interests and inferred tech stack from your searches (never raw queries) and starts surfacing tools you wouldn't have found otherwise. You can see exactly what it stores and clear it anytime at /developer.

The market gap data has been the most interesting part. Every failed search gets logged and we're seeing real demand patterns for stuff that either doesn't exist or just isn't discoverable. Turns out there's a massive gap in developer file conversion tools -- that's not something we would have guessed.

I've personally contacted about 200 makers over the past few weeks and the pattern is always the same. Someone built something genuinely useful, it has maybe 50 GitHub stars, and nobody outside their immediate circle knows about it. The tools aren't bad, they're just invisible. There's no knowledge layer connecting what's been built to who needs it, especially not for agents.

The whole thing runs on Python/FastAPI/SQLite on a single Fly.io machine for about $5/mo. No React, no build step, pure Python string templates. 11 MCP tools including personalized recommendations and a stack builder that suggests full toolchains for a project description.
