headroom vs perseus-vault
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.; perseus-vault: Perseus Vault provides durable, encrypted, local-first memory for AI agents, operating as a single Rust binary with zero dependencies. It integrates seamlessly with popular AI agent frameworks like LangGraph, CrewAI, and AutoGen, offering advanced features like hybrid semantic search, bitemporal queries, and a robust memory lifecycle.
01
TL;DR
headroomMemory & Context · ★ 77.3k
When to choose:
- Long tool output, logs, JSON responses or RAG chunks are driving up cost or hurting answers.
- You want compression without code changes: run it as a local proxy, an MCP server, or by wrapping Claude Code, Codex or Cursor.
- Compression must run locally, with originals cached so the model can retrieve the full text.
When to skip:
- Your agent's problem is missing or outdated docs, not too much context: a docs server fits better.
- You cannot add a component that must keep running and may add latency.
- Your tasks cannot tolerate lossy compression: verify answer quality on your own work first.
