Devtoolwatch BoardGraphiti review
Graphiti is an open-source Python framework for building and querying temporal knowledge graphs, called context graphs, for AI agents.
TL;DR
Graphiti is an open-source Python framework for building temporal context graphs that track how facts change over time. It is for developers building AI agents on evolving data. Graphiti updates graphs incrementally, keeps provenance to source episodes, and uses hybrid semantic, keyword, and graph retrieval. You bring your own graph database.

What Graphiti does
- Graphiti builds temporal knowledge graphs where each fact has a validity window, and old facts are invalidated rather than deleted.
- Graphiti traces every entity and relationship back to the episodes, the raw data that produced it.
- Graphiti ingests text and structured JSON episodes and integrates new data without batch recomputation of the graph.
- Graphiti combines semantic embeddings, BM25 keyword search, and graph traversal for hybrid retrieval.
- Graphiti supports custom entity and edge types defined as Pydantic models, or structure learned from your data.
- Graphiti answers historical queries about what was true at any point in time.
- Graphiti includes reference MCP and REST servers that show how to put the library behind a protocol.
How it works
Graphiti is a Python library, graphiti-core, that you run in your own service. It connects to a graph database: Neo4j, FalkorDB, Amazon Neptune with OpenSearch Serverless, or the deprecated Kuzu. It uses OpenAI by default for LLM inference and embeddings. Anthropic, Gemini, Groq, and OpenAI-compatible endpoints such as Ollama or vLLM are also supported.
How to install and start using Graphiti
With pip
pip install graphiti-coreWith uv
uv add graphiti-coreWith FalkorDB support
pip install graphiti-core[falkordb]Requirements
- Python 3.10 or higher
- A graph database: Neo4j 5.26, FalkorDB 1.1.2, Amazon Neptune with OpenSearch Serverless, or Kuzu 0.11.2 (deprecated)
- An OpenAI API key by default; Anthropic, Gemini, or Groq keys are optional alternatives
- Python 3.12 or higher for the embedded FalkorDB Lite option
First steps
- Start a graph database, for example Neo4j with Docker Compose using docker compose up.
- Set OPENAI_API_KEY in your environment, since Graphiti defaults to OpenAI for inference and embeddings.
- Connect to the database and initialize Graphiti indices and constraints, as shown in the quickstart example.
- Add text or JSON episodes, then search relationships with hybrid search and rerank by graph distance.
Who Graphiti is for
- Developers building AI agents that need memory of facts that change over time
- Applications that need precise historical queries and provenance back to source data
- Teams comfortable building and operating the surrounding system around an open-source core
Limitations to know
- Graphiti is self-hosted only and requires you to bring your own third-party graph database.
- Graphiti works best with LLMs that support Structured Output; other services, especially smaller models, may cause ingestion failures.
- The reference MCP and REST servers have no authentication, authorization, or prompt-injection protection and are not production deployments.
- Kuzu support is deprecated and will be removed in a future release.

What are the best alternatives to Graphiti?
Other RAG, data and memory tools on the Devtoolwatch Board in the week of Oct 25–31, 2026, by momentum: XERJ (#1), Memvid (#2), LEANN (#3), Graphify (#4), MarkItDown (#5). The alternatives table above has their numbers.
What is a Graphiti knowledge graph?
A Graphiti knowledge graph is a temporal context graph of entities, relationships, and facts. Each fact has a validity window showing when it became true and when it was superseded. Everything traces back to episodes, the raw ingested data.
How does Graphiti relate to Zep?
Graphiti is the open-source framework at the core of Zep's context infrastructure. Zep is managed infrastructure with a proprietary graph database, user management, and dashboards. Graphiti is self-hosted and builds individual context graphs on your own database.
How is Graphiti different from GraphRAG?
Graphiti targets dynamic data with continuous incremental updates. It uses hybrid semantic, keyword, and graph search and bi-temporal fact invalidation. The README describes GraphRAG as batch-oriented static document summarization using sequential LLM summarization.
Can Graphiti use local LLMs?
Graphiti can use local servers such as Ollama, vLLM, llama.cpp, and LM Studio through their OpenAI-compatible endpoints. Models without Structured Output support may produce incorrect schemas.
How do I avoid LLM rate limit errors in Graphiti?
Graphiti controls ingestion concurrency with the SEMAPHORE_LIMIT environment variable, which defaults to 10. Lower it if you hit 429 errors, or raise it if your provider allows more throughput.
