MIND vs Graphiti

An open-source (Apache 2.0) framework for building real-time, temporally-aware knowledge graphs — the engine that powers Zep, usable on its own with Neo4j, FalkorDB, Amazon Neptune, or Kuzu.

Graphiti is not a competitor in the usual sense — it's infrastructure, full stop, and it's worth being precise about what that means: it's the open-source engine underneath Zep, released separately as an Apache 2.0 library so anyone can build their own temporal-graph memory system without paying for Zep's hosted platform. If you want the technical sophistication behind Zep's context assembly — time-bound fact validity, episode-based provenance tracing every fact back to its source, hybrid semantic-plus-keyword-plus-graph retrieval — without the hosted product, Graphiti is genuinely that engine, exposed.

The comparison to MIND is really a comparison of build-it-yourself versus use-the-built-thing. Graphiti gives you the primitives to construct a memory system with real temporal reasoning, on whichever graph database you choose, Neo4j, FalkorDB, Neptune, or Kuzu, and it even ships its own MCP server so an agent can query the graph you build. What it doesn't give you is a product: no app, no hosted account, no consumer surface — you're the one who stands up the database, writes the ingestion logic, and decides what an episode is. MIND is what you get if someone already did that work and handed you the finished graph, reachable by every model you use, with nothing to deploy.

For a team that specifically needs temporal reasoning, what did we believe about this customer six months ago versus now, and wants full infrastructure control, Graphiti is a serious, well-engineered choice, and it's free. For a person who wants memory without becoming the person who runs a graph database, that's the entire reason MIND exists.

The choice of graph database backend is itself a meaningful decision Graphiti hands you rather than making for you: Neo4j is the mature, widely-supported default; FalkorDB is built for lower-latency graph queries; Amazon Neptune suits a team already committed to AWS; Kuzu is the embeddable, no-server option. Each has real tradeoffs in query performance, operational overhead, and cost, and Graphiti's design means you're the one evaluating them. MIND makes that decision invisible — there's no database to choose, because there's no database for you to operate at all.

Graphiti's graph lives in whichever database backend you chose (Neo4j, FalkorDB, etc.), and its episodes and entities can be queried out and re-ingested into MIND as documents; the temporal validity windows themselves, what was true when, don't have a direct MIND equivalent, since MIND doesn't currently expose fact-versioning as a feature. Most teams using Graphiti keep it for the specific temporal-reasoning workload it's built for and use MIND separately for a person's own memory.
