Graphiti vs Vectara

A side-by-side look at pricing, capabilities, pros, cons, and our editorial scores.

	Graphiti RAG	Vectara RAG
Tagline	Open-source temporal knowledge graph framework for building agent memory that updates in real time.	Enterprise agent platform with built-in retrieval, grounding, and hallucination controls
Category	RAG	RAG
Pricing	Freemium· Basic: $10 · Pro: $30 · Enterprise: $100	Enterprise· Free Trial: Free · SaaS: $100K/ year · VPC: $250K/ year · On-prem: $500K/ year
Model	Multi-model	In-house Boomerang (retrieval) and Mockingbird (generation) plus BYOM for GPT, Claude, Gemini, and open-weight LLMs
Editorial score	7.2 / 10	—

Pros	Real-time incremental graph updates without batch recomputation Temporal model tracks when facts were valid, not just current state Hybrid semantic + keyword + graph search out of the box Open source with an active commercial backer in Zep MCP server lets Claude Desktop and Cursor read agent memory directly	End-to-end managed RAG stack — you ship documents and queries, Vectara handles chunking, embeddings, vector store, retrieval, reranking, and grounded generation Built-in hallucination detection (HHEM) that scores factual consistency of every response, not just a black-box confidence number Automatic citation of source passages, essential for legal, medical, and financial use cases Model-agnostic — bring your own LLM (OpenAI, Anthropic, Google, open weights) while keeping Vectara's retrieval and safety layers Deployment flexibility including single-tenant VPC and fully on-premise for regulated / air-gapped environments Handles multimodal ingestion (text, tables, images in PDFs) without extra plumbing Version-aware retrieval and role-based access controls suited to enterprise governance requirements
Cons	Requires running a graph database like Neo4j LLM calls during ingestion add cost vs plain vector RAG Steeper learning curve than drop-in RAG libraries	Enterprise pricing only — starts at $100K/year for SaaS and climbs to $500K/year for on-prem, ruling out solo devs and small teams No transparent self-serve tier beyond the 30-day trial; production use requires a sales conversation Core platform is closed-source (only the HHEM eval model is open); teams wanting to inspect or fork the retrieval stack should look elsewhere Opinionated pipeline means less control over individual components (custom chunkers, exotic rerankers) than a DIY LangChain/LlamaIndex stack Heavier onboarding than lightweight vector-DB-plus-LLM setups; overkill for prototypes or single-app use
