Headroom
Compresses noisy tool output before it reaches Claude Code or ChatGPT to cut token usage
Headroom runs as a local proxy that intercepts prompts before they reach Claude Code or ChatGPT, reversibly compressing the logs, JSON, and boilerplate that eat up tokens. The vendor reports about 50% compression on noisy inputs like tool results and logs, and 40-50% fewer tokens across a full agentic coding session. All optimization happens on your machine, so prompts and code don't leave it. It's a menu bar app with a 7-day free trial and no credit card required to start.
What holds up
- +Runs as a local proxy — your prompts and code never leave your machine
- +Compression is reversible, so the model can still retrieve the original content on demand
- +7-day free trial, no credit card required to start
Mind the limits
- −Only integrates with Claude Code and ChatGPT/Codex — no support for other coding agents
- −Savings are self-reported benchmarks, not independently verified, and vary by workload
