Score: 4.3/10 (Innovation: 4, Technical: 5, Documentation: 2, Utility: 4)

PreFlight is a local AST background daemon that aims to catch structural anomalies and code drift in AI-generated code, particularly around Supabase Row-Level Security issues. It is interesting as a real-time guardrail for AI-assisted development, but remains in early beta with minimal documentation and unclear implementation.

Target audience: backend devs, data engineers
