Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

Postbrain provides long-term memory for AI coding agents by storing session observations, curated knowledge, and versioned prompt templates in PostgreSQL. It addresses the critical problem of AI context loss across sessions, combining multiple database extensions and a REST API to create a durable knowledge layer for agent teams.

Target audience: backend devs, ai engineers, devops
