It offers a library, proxy, and MCP server; pick pruna if pruna is a Python framework focused on delivering quicker and leaner AI models for developers across Linux, MacOS, and Windows platforms. [headroom](https://docs.headroomlabs.ai/docs) reports 73k GitHub stars, 5.6k forks, and 671 open issues, last pushed Sep 17, 2026. [pruna](https://docs.pruna.ai) has 1.3k stars, 110 forks, and 10 open issues, last pushed Sep 21, 2026.
