Analysis of Graphiti

Overall verdict

  • Graphiti is a well-regarded open-source framework for building real-time, temporally-aware knowledge graphs, particularly useful for AI agents and applications that need persistent, evolving memory. It's actively maintained by Zep and has gained solid traction in the LLM and agent development community.

Why this product is good

  • Purpose-built for real-time knowledge graphs that update incrementally without full recomputation
  • Temporal awareness lets it track how facts and relationships change over time
  • Designed specifically for AI agent memory, enabling more context-aware and persistent applications
  • Integrates with LLMs and supports hybrid retrieval (semantic, keyword, and graph-based search)
  • Open-source with active development and backing from Zep, plus growing community adoption
  • Scalable architecture suitable for production use cases involving dynamic data

Recommended for

  • Developers building AI agents that need long-term, evolving memory
  • Teams creating LLM-powered applications requiring context-aware retrieval
  • Projects needing temporally-aware knowledge graphs that track changes over time
  • Use cases involving dynamic, frequently-updated data rather than static datasets
  • Engineers exploring alternatives to traditional RAG for more structured, relational context

  • Ask HN: What Are You Working On? (April 2026)
    I'm working on Watch.ly - a remote human-in-the-loop networking and FS sandbox for AI agents like openclaw: https://watch.ly/ Also this week launching https://dirtforever.net/ which is an open alternative to RaceNet Clubs for Dirt Rally 2, since EA is shutting that down. I'm also expanding the SDK and plugin space for https://fastcomments.com and am planning on adding AI agents because everyone expects that now :)... - Source: Hacker News / 4 months ago
  • Ask HN: What are you working on (August 2024)?
    Hello! This year I've been working on building an integrated registration and live timing platform [0] for my local organizers in CA, but it is spreading. Very fun/rewarding project. I hope to launch my own cellular-based timing hardware this year which will integrate into the timing platform (right now I've reverse engineered and now support 5 different chronometers, I never knew cross platform serial port comms... - Source: Hacker News / almost 2 years ago
  • Commenting system for Hugo
    Another one I can recommend enthusiastically but forgot to mention before, is a paid service called FastComments (https://fastcomments.com/). Great, non-heavy code with a super-helpful developer. Source: about 4 years ago
  • Made this NPM package that saves you the trouble of making a tedious comments section!
    With a quick search, I found https://fastcomments.com/, which does provide comments storage. What does your library provide that this service doesn't? Source: about 4 years ago
  • How do you collect feedback for your blog posts? (for technical blogs, documentation, how-to's, etc.)
    I just started using https://fastcomments.com/. I am still in the free trial but it seems pretty good so far. Source: over 5 years ago

  • Your AI Agent Forgets Everything After Every Session. Graphiti Fixes That.
    Graphiti is an open-source framework by Zep for building and querying temporal context graphs for AI agents. It's the engine behind Zep's managed memory platform, but it's fully usable standalone. - Source: dev.to / about 1 month ago
  • I Tested 33 AI Memory Engines โ€” Here's What Actually Works
    Graphiti by Zep is the temporal knowledge graph. Its core insight: knowing the current state isn't enough. You need to know when things changed and what was true before. - Source: dev.to / 2 months ago
  • I Built Two Ollama Tools I Don't Actually Need Yet
    Several services share the same Ollama instance on a dedicated host that homelab-agent is provisioning: LibreChat for interactive chat, a SearXNG MCP server for ML-reranked search, and three background embedding jobs โ€” graphiti, jobsearch-mcp, and memsearch-watch. - Source: dev.to / 3 months ago
  • I Benchmarked Graphiti vs Mem0: The Hidden Cost of Context Blindness in AI Memory
    It started with a 35,000-token "Master Prompt" that she maintained manually in Notion. Every time something changed in her life, she updated it by hand. That obviously didn't scale. So I moved to Graphiti, a knowledge graph framework that extracts entities and relationships from conversations automatically. - Source: dev.to / 4 months ago
  • Show HN: A file-based agent memory framework that works like skill
    - *[Zep](https://github.com/getzep/graphiti)* uses graphs, which handle structure well but add complexity and maintenance overhead. - Source: Hacker News / 7 months ago
