headroomlabs-ai · Context Compressor

Headroom v0.37.0

Context compression for agents, shrinking prompts, tool outputs, logs, RAG chunks and files before they reach the model. Claims 20% token reduction on coding-agent output and 60-95% on structured JSON at roughly 0.21ms overhead, routing by content type through SmartCrusher for JSON, an AST-aware compressor for code and a proprietary Kompress-v2-base model for prose. Ships as a library, a drop-in proxy, direct wrappers for Claude Code, Cursor, Codex and Cline, and an MCP server. Apache-2.0, 71,781 stars, v0.37.0 on 27 August.
