What each one is
LangGraph
LangGraph is a library for building stateful, controllable agents as graphs, giving you fine-grained control over loops, branching and persistence.
- Explicit, controllable agent state machines
- Persistence and human-in-the-loop built in
- Integrates with the LangChain ecosystem
Mem0
Mem0 is a memory layer that gives agents and assistants persistent, personalized memory across sessions, with APIs to store, search and consolidate memories.
- Persistent, personalized agent memory
- Automatic memory extraction and consolidation
- Self-hosted or managed, framework-agnostic
Key differences
LangGraph is agent orchestration (graphs), while Mem0 is agent memory layer. Their licenses differ (MIT vs Apache-2.0), which matters if you ship a commercial product. LangGraph leans more advanced-friendly, whereas Mem0 is more suited to intermediate users. They also differ in how they run (Cloud-optional vs Self-hosted). In short, LangGraph fits developers needing controllable agent workflows, and Mem0 fits developers adding persistent memory to agents.
Which should you choose?
Choose LangGraph for developers needing controllable agent workflows. Choose Mem0 for developers adding persistent memory to agents.
There is rarely one winner — many setups use both. The right pick depends on your hardware, your team's skills, and whether you value simplicity or control.
