The Memory OS for
Autonomous Agents
Graph-Powered Persistent Memory + Multi-Agent Orchestration
Give your AI a brain that remembers, learns, and builds knowledge over time. Free, open-source, and enterprise-ready.
Why Mimir Exists
Most AI agents forget everything between conversations. Mimir changes that.
Graph-Powered Memory
Not just a vector store—a living knowledge graph that understands relationships between tasks, files, and concepts. ACID transactions guarantee your data is always consistent.
Multi-Agent Coordination
PM → Worker → QC workflows out of the box. Multiple agents share a single brain, preventing conflicts with built-in locking and coordination.
Code-Aware Intelligence
Automatically indexes your codebase, tracks architecture decisions, and surfaces relevant context. Perfect for developers managing complex projects.
Semantic Search
Find tasks by meaning, not keywords. Vector embeddings + graph traversal = discover connections you didn't know existed.
Enterprise-Ready Security
RBAC, OAuth 2.0, audit logs, multi-tenant isolation. Built on Neo4j's battle-tested transactional guarantees.
100% Self-Hosted
Your data stays on your infrastructure. No vendor lock-in, no usage limits, no subscription fees. MIT licensed and truly free.
What Makes Mimir Different
The only open-source solution combining Graph-RAG with multi-agent orchestration
🕸️ Native Graph Intelligence
Competitors store isolated vectors. Mimir understands how everything relates—tasks, files, concepts, and decisions.
🤝 Multi-Agent by Design
Built-in PM/Worker/QC patterns. Most frameworks have no concept of shared agent memory or coordination.
💾 ACID Transactions
Neo4j guarantees data consistency. Vector databases don't—your data could be corrupted and you'd never know.
🔌 MCP Protocol Native
Direct integration with Claude, ChatGPT, and any MCP-compatible assistant. No custom adapters needed.
📊 Visual Debugging
Mimir Studio lets you see agent memory, task dependencies, and knowledge graphs in real-time. Competitors give you logs.
💰 Truly Free Forever
MIT licensed with no catches. Pinecone starts at $70/mo, Weaviate at $25/mo. Mimir: $0.
