Show HN: Reduce Claude Code token usage ~50% with Headroom

What is Headroom?
Headroom is a macOS menu bar app that reduces Claude Code token usage by approximately 50% without impacting output quality. It works by intercepting every prompt before it reaches Claude, stripping out logs, boilerplate, and repetitive content, then forwarding only what the model needs. The app uses reversible compression for tool output, boilerplate, and large inputs before Claude Code stores them in the conversation, allowing Claude to pull back original content on demand if needed.
Key features include privacy-first local processing (prompts never touch Headroom servers), smart optimization that cuts noise before Claude Code sees it, self-contained runtime that never interferes with project packages, reversible compression with a retrieval tool for original content, preservation of Anthropic's prompt cache prefix, and support for sub-agent token error reduction. The app has saved users over 10.7 billion tokens and delivers benchmark results showing strong quality retention across reading comprehension, tool calling, HTML recall, and JSON-heavy workloads.
Headroom is designed for developers who rely on Claude Code and want about 2x as much usage on the Claude plan they already pay for by cutting token waste and keeping large codebase sessions efficient without changing their workflow. It is particularly helpful for sessions involving verbose tool output like code search, logs, HTML, or long documentation. The desktop app is based on the open-source Headroom CLI project created by Tejas Chopra, with endorsement from the maintainer.
The app currently offers a macOS version only and includes an ROI calculator showing teams can get up to 8x return on Headroom spend based on ~2x token efficiency. It offers a 14-day trial and multiple pricing tiers matching different Claude subscription levels, from free limited usage to enterprise plans with private deployment options.

Frequently asked questions about Headroom
What does Headroom do for Claude Code?
Headroom is a menu bar app that reduces Claude Code token usage by reversibly compressing tool output, boilerplate, and large inputs before Claude Code stores them in the conversation. The plan you already pay for lasts longer, and Claude can pull the original content back if it needs it.
Does Headroom keep quality intact?
Yes, that is the goal. Headroom is built to remove repetitive or low-signal tokens while preserving the information Claude Code needs to answer correctly. Benchmark results show strong quality retention across reading comprehension, tool calling, HTML recall, and JSON-heavy workloads, with 0.919 HTML extraction F1 score and improved QA accuracy by 2% on SQuAD v2/HotpotQA.
Is Headroom's compression lossy?
No. Headroom's compression is reversible. When it shrinks a tool output or an older message, it includes a small retrieval tool that lets Claude pull back the original content on demand, so nothing is actually thrown away. You simply stop paying for tokens Claude does not need on every turn.
Does Headroom break Anthropic's prompt cache?
No. Headroom is designed to preserve the cached prefix of your conversation. Tool outputs are compressed before they enter the conversation history, and stale messages later in the thread are compressed without altering the prefix Anthropic has already cached. The maintainer of the underlying Headroom CLI has reported around a 97% prefix cache hit rate from production usage.
How much latency does Headroom add?
Production data from the underlying Headroom CLI puts median overhead at roughly 52 milliseconds per request, on par with a single network round-trip and small compared to the seconds Claude itself takes to respond. Most people do not notice it.
Does Headroom send my prompts to your servers?
No. Headroom is privacy-first and runs locally on your machine, so your prompts do not need to be shipped to a Headroom server for optimization. Everything processes on your local machine.
Who is Headroom for?
Headroom is designed for developers who rely on Claude Code and want about 2x as much usage on the Claude plan they already pay for by cutting token waste and keeping large codebase sessions efficient without changing their workflow. It is especially helpful for sessions involving verbose tool output like code search, logs, HTML, or long documentation.
Does Headroom help with sub-agent token errors?
Yes. Sub-agents in Claude Code lose the parent session's prefix-cache benefit and can hit their own token limits quickly once tool output piles up. Headroom compresses sub-agent tool output the same way it compresses the main session, so the same task fits in fewer tokens.
Which platforms does Headroom support?
Headroom currently offers a macOS app only. There is no Windows or Linux support available at this time.
How should I evaluate whether Headroom is worth it?
Start with the free tier or trial, compare token usage before and after installing it, and look at sessions that involve verbose tool output like code search, logs, HTML, or long documentation, since those are the areas where optimization tends to help most. If your normal workload lands around 50% lower token usage, that is effectively about 2x as much Claude Code usage on the Claude plan you already pay for.
