headroom
headroomlabs-ai/headroom · ★ 75.5KHeadroom compresses everything an AI agent reads - tool outputs, logs, RAG chunks, files, and conversation history - before it reaches the LLM, cutting tokens while keeping the same answers. It ships as a library, a local proxy, and an MCP server.
+36vm2api
dofastted/vm2api · ★ 1.2Kvm2api is a self-hosted proxy that runs your Claude/Anthropic (or OpenAI-compatible) API traffic through a real-looking virtual machine or Docker 'slot' so the account looks like a genuine Claude Console client instead of relying on system-prompt tricks or persona injection.
