Show HN: Reduce Claude Code token usage ~50% with Headroom (extraheadroom.com)

A new menu bar application called Headroom has been launched to help Claude Code users significantly reduce their token usage by approximately 50%. This app operates locally on macOS, ensuring that user prompts remain private and do not touch external servers. By intelligently optimizing inputs—trimming unnecessary prompt bloat, stripping boilerplate content, and compressing documents—Headroom allows users to double their usage on their existing Claude subscription without diminishing output quality. Headroom's functionality is grounded in rigorous technical benchmarks, demonstrating its capability to intercept prompts before they reach Claude, effectively eliminating noise without losing signal. Users can trial the app for 14 days and choose plans that align with their Claude tier, offering significant cost savings and improved efficiency. With its foundation in the open-source Headroom CLI project, this application not only enhances the user experience but also provides resources for understanding and managing Claude Code costs, making it a valuable tool for the AI/ML community focused on optimizing usage while maintaining performance.
