About
Headroom is a menu bar app for macOS, Windows and Linux 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.
It compresses the bulky tool output, logs and boilerplate your coding agent sends. Compression runs locally, before the request leaves your machine, so prompts and code stay private. Source code passes through untouched, and the originals stay available to the agent through a retrieval tool.
Typical coding sessions save 25-50% overall. Across 183 Claude Code users over one week, Headroom cut input tokens by 34% (measured) and output tokens by 33% (estimated).
Also included: a dashboard and activity feed with tokens and API-equivalent dollars saved, project learnings that turn past sessions into token-saving rules, and one-click add-ons (MarkItDown, Serena, Codebase Memory, Context7, Ponytail, Caveman).
7-day free trial, no credit card. Plans from $3/month.

About
Codex is an AI-powered coding agent from OpenAI designed to help developers build, manage, and ship software more efficiently across the entire development lifecycle. It acts as an intelligent pair programmer that can understand codebases, generate features, and deliver production-ready pull requests. Codex can safely execute commands in sandboxed environments while assisting with debugging, refactoring, and testing. A key advancement is its computer use capability, allowing it to operate your computer by seeing, clicking, and typing across applications. This enables Codex to interact with tools that don’t have APIs, making it useful for tasks like frontend testing and app navigation. The platform also includes an in-app browser and integrations with various developer tools for a more unified workflow. Codex supports automation by handling ongoing tasks such as monitoring, issue triage, and follow-ups.
