Local proxy that compresses large tool outputs before coding agents read them, reducing token costs 20–30%.
Codag installs as a per-user local service that intercepts large tool results (logs, test outputs, search results, file listings) before they reach a coding agent, compressing them to essential signal while keeping exact omitted content encrypted on-device and retrievable on demand by line range or JSON path. It attaches to Claude Code and Codex without changing the agent, prompts, provider account, or model. A free tier includes 10 credits (~1 GB); paid plans are $0.05 per credit (~100 MB) or $499/month for teams. Codag is a product of Codag.
