Score: 7.8/10 (Innovation: 7, Technical: 8, Documentation: 9, Utility: 7)

Velocity is a self-hosted, keyless flight and ship tracker that stores position history in TimescaleDB for unlimited rewind capability, unlike commercial APIs with time-limited replay. It adds multi-source provenance scoring, an evidence locker with SHA-256 custody chains, and an MCP server for AI agent integration, all while maintaining honest scope and disclaimer about data reliability.

Target audience: OSINT analysts, aviation enthusiasts, maritime researchers, backend developers
