Apache-2.0 temporal knowledge graphs for agent memory; Zep's OSS engine
AI Agents / Memory & Evals · Apache-2.0 · 30.6k
What's Good
Apache-2.0. Episodes → entities/edges with validity windows; hybrid retrieve (embeddings + BM25 + graph). Neo4j/FalkorDB/Kuzu/Neptune. MCP server for agent IDEs. Powers Zep's managed context lake.
The Catch
Framework only — you run a graph DB + ops. Zep Community Edition deprecated; full Zep SaaS is separate (Free credits then Flex ~$104/mo billed annually). Not a drop-in chat history store. Schema/ops cost vs Mem0 Docker.
Verdict
Apache-2.0 temporal memory graphs. Free self-host; Zep Cloud is the paid path.
