# headroom vs mempalace

headroom and mempalace share 3 technologies: rusqlite, SQLite, and tokenizers. Both are written in Python.

- [headroomlabs-ai/headroom](https://seerepo.com/r/headroomlabs-ai/headroom): Compress tool outputs, logs, files, and RAG chunks before they reach the LLM. 20% fewer tokens for coding agents, 60-95% fewer tokens for JSON, same answers. Library, proxy, MCP server.
- [MemPalace/mempalace](https://seerepo.com/r/MemPalace/mempalace): The best-benchmarked open-source AI memory system. And it's free.

## What they share and what sets them apart

- In common: rusqlite, SQLite, tokenizers
- Only in headroom: FastAPI, axum, Redis, lru, Tokio, tower, Rich, gcp_auth, autogen-agentchat, litellm, hf-hub, ort, tiktoken, tiktoken-rs, Pydantic, OpenTelemetry, tracing, prometheus, tracing-subscriber, @opencode-ai/plugin, @ai-sdk/provider, ai
- Only in mempalace: chromadb, Hugging Face

| Tests | 1,220 test files. 68.2% of its code files have a test that imports them | 304 test files. 70.2% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
