gum vs headroom
gum: gum is a single binary CLI tool designed to provide a safer and more efficient interface for agents and humans to interact with Google APIs. It features an embedded API catalog, local authentication helpers, and risk gates, significantly reducing the complexity and token usage associated with direct Google API interactions.; headroom: Headroom compresses everything your AI agent reads — tool outputs, logs, RAG chunks, files, and conversation history — before it reaches the LLM. It achieves the same answers with a fraction of the tokens.
01
TL;DR
Choose gum if…Allowing AI agents to safely inspect and interact with Google Workspace services like Gmail, Drive, and Calendar.
Choose headroom if…Reduce LLM token usage and API costs for AI agents.
