aicoolies is a free Developer Tools Knowledge Graph: a source-checked catalog of 1,300+ AI developer tools with written comparisons, reviews, and curated stacks. Every review shows its evidence label and the date its sources were checked. Use it to choose coding agents, MCP gateways, inference runtimes, and the rest of a real toolchain. It is a catalog and decision surface, not a coding agent and not a scraped AI-tools dump.
