headroom vs celiums-memory
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.; celiums-memory: Celiums Memory is a cognitive memory engine designed to be embedded within other software like agents and assistants, providing persistent memory, journaling, and an auditable ethics engine. It speaks the Model Context Protocol (MCP) to offer these advanced cognitive capabilities without requiring developers to build them from scratch.
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- Your agent's problem is missing or outdated docs, not too much context: a docs server fits better.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.
