Headroom

About Headroom

Headroom is a macOS menu bar app that sits between your coding agent and the model and reversibly compresses the bulk that dominates most prompts — verbose tool output, logs, boilerplate and repeated file content — so Claude Code and Codex consume roughly half the tokens for the same work. The important word is reversible: the original content is retrievable on demand, so the model can pull back anything it actually needs rather than being handed a lossy summary and guessing. The practical effect is stated as about twice the usable work on the plan you already pay for, which addresses the specific failure mode the site leads with — burning the weekly limit by Wednesday and rationing the rest of the week. Everything runs locally: prompts and code never leave the machine, and the app is self-contained rather than injecting itself into your project's package tree, so it cannot interfere with the dependencies a project already has. The site publishes running counters for installs, cumulative tokens saved and equivalent dollar value at API rates, plus a benchmarks section and a comparison against alternative approaches including the Ponytail skill and RTK. There is an extensive articles library on Claude Code and Codex usage mechanics — what counts against a limit, how the five-hour window works, why costs run high — which doubles as genuinely useful reference material independent of the product.
