lossless-code vs headroom
lossless-code: lossless-code is a DAG-based lossless context management tool for Claude Code. It preserves every message forever, cascades summaries in a directed acyclic graph, and provides full recall across sessions. It works with any LLM and has zero background processes.; 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.

TL;DR
lossless-codeMemory & Context · ★ 15
Maintain full context across multiple Claude Code sessions
headroomMemory & Context · ★ 77.5k
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- Your agent's problem is missing or outdated docs, not too much context: a docs server fits better.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.
