engram

Engram is an open-source devtool that functions as a persistent context spine for AI coding assistants, operating locally via SQLite across eight major IDEs including Claude Code and Cursor. It achieves a measured 89% token reduction by intelligently managing and reusing session context, making it valuable for developers seeking to dramatically lower costs and improve AI coding efficiency without cloud dependency. Its Apache 2.0 licensing and zero-cloud architecture make it particularly interesting for privacy-conscious teams and power users who want to 10x their AI-assisted development workflows.
