## In short

Headroom v0.26.0 shipped on 2026-06-16, adding Copilot BYOK provider wrappers and CLI support, Mistral Vibe CLI support, and an AWS Bedrock InvokeModel/Converse compression proxy. The Apache-2.0 context compressor has crossed 36,900 stars and topped GitHub trending this week.

## What it is

Headroom sits between an agent and an LLM and compresses anything that flows in: tool outputs, log dumps, file reads, RAG chunks, and conversation history. It runs as a Python or TypeScript library, an OpenAI-compatible proxy, an MCP server, or a CLI wrapper around Claude Code, Cursor, Codex, Aider, OpenHands, and similar agents.

## How it works

Six compression algorithms specialize by content type — SmartCrusher for JSON, AST-aware CodeCompressor for source, Kompress-base for prose, ContentRouter to pick between them, CacheAligner for prefix reuse, and CCR for reversible compression where the original data stays local and the LLM can request the full payload if it needs it. Cross-agent memory lets Claude, Codex, and Gemini share a deduplicated context store.

## Why it matters

Token bills are the new dominant cost line for production agents (Uber just capped its coding spend after blowing the annual budget in 4 months). Headroom hit GitHub trending #1 today with 1,265 stars in 24 hours because it offers a Python pip install that benchmarks claim cuts cost ~10× without rewriting prompts.

## Who it's for

agent builders and platform teams trying to keep token spend from outpacing ROI

## Try it

pip install "headroom-ai[all]" && headroom proxy --port 8787
