Headroom

Headroom is a macOS menu bar application designed to significantly reduce the token costs associated with using AI coding assistants like Claude Code and Codex. It works by quietly intercepting prompts before they reach these models and reversibly compressing the bulky, often noisy, elements such as tool output, logs, and boilerplate code. This optimization can cut token usage by approximately 50%, effectively doubling the usable capacity of existing AI subscriptions without requiring users to upgrade their plans.

The tool operates locally on your machine, ensuring that prompts and code remain private and never leave your device. Headroom functions as a local proxy, intelligently identifying and compressing repetitive or extraneous information while ensuring that all necessary data remains retrievable by the AI model on demand. This process maintains the quality of the AI's output, as Headroom strips only noise, not essential signal, allowing developers to get the same results with fewer tokens.

Headroom is ideal for software developers, AI engineers, and teams who frequently use Claude Code or Codex and find themselves hitting token limits or incurring high costs. It helps extend the value of their AI subscriptions, allowing for more extensive use of these powerful coding assistants. The tool offers a 7-day free trial, making it easy for users to experience the cost savings firsthand before committing to a plan.
