headroom vs mermaid-code
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.; mermaid-code: Mermaid Code is a local-first desktop editor for Mermaid diagrams, built on Mermaid Live Editor and enhanced with Tauri for native features. It integrates AI agents like Claude Code and Codex, allowing them to create, modify, and explain diagrams directly within the app, leveraging local file access and an MCP server for AI-native workflows.
