Headroom Reviews & Product Details

Headroom is a menu bar app that cuts Claude Code and ChatGPT Codex token costs by ~50%, which can translate to up to 2x as much usage on the plan you already pay for. Headroom quietly optimizes the inputs your coding agent sends by compressing the bulky tool output, logs, and boilerplate that devour tokens. Compression runs locally on macOS, Windows and Linux, before the request leaves the machine, so prompts and code stay private. Source code passes through untouched, and the originals stay available to the agent through a retrieval tool, so answers stay the same. On the noisiest inputs (JSON tool results, logs, long documents) compression runs at ~50% and up; typical real-world coding sessions land around 25-50% overall. In production, across 183 Claude Code users over one week, Headroom reduced input tokens by 34% (measured) and output tokens by 33% (estimated). Key features: - Works with Claude Code and ChatGPT Codex, no workflow changes - Dashboard and activity feed with tokens and API-equivalent dollars saved - Project learnings that turn past sessions into token-saving rules - One-click add-ons: MarkItDown converts documents to Markdown, Serena adds symbol-level code tools, Codebase Memory keeps a knowledge graph of the repo, Context7 fetches current library docs, and Ponytail and Caveman keep the agent's code and replies lean - Self-contained install that does not touch your project dependencies Plans are matched to each developer's Claude or ChatGPT tier, with a 7-day free trial and no credit card required. Teams can ask about rollout controls and private deployment.
