Mem0 alternatives (2026)
Mem0 is a memory & RAG tool: Mem0 is an open-source memory layer for AI agents that extracts facts from conversations in a single add-only pass, links entities across memories and retrieves them in later sessions, with an Apache-2.0 SDK and a managed platform. Pricing, as the maker states it: Open source SDK (Apache-2.0); managed platform: Hobby free, Starter $19/mo, Pro $249/mo, Enterprise custom. Its GitHub repo has 67,147 stars. We found 53 tools in the directory that do overlapping work (building AI agents, memory for agents); 47 of them are open source and 2 list a free or freemium plan. Below are the 10 closest, ranked by how many tasks and sub-tasks they share with Mem0, then by GitHub stars.

- SimpleMem (Open source): Research-backed lifelong memory library for LLM agents that stores, compresses and retrieves text and multimodal memories, usable over MCP. Consider it because it also covers research and reports.
- Memori (Open source + cloud): An LLM-, database- and framework-agnostic memory layer that turns what agents do and say into structured, persistent state they can recall in later runs. Open source to self-host, or use Memori Cloud with an API key. Consider it because it also covers SQL and databases.
- llmware (Open source): Framework for building private, local RAG and agent applications with small specialized models on AI PCs, edge and self-hosted setups. Consider it because it also covers local and self-hosted.
- txtai (Open source): All-in-one Python framework for semantic search, LLM orchestration and agents built on an embeddings database of vector, graph and relational indexes. Consider it because it also covers SQL and databases and multi-agent orchestration.
- Honcho (Open source + cloud): Memory library and service for building stateful agents that remember users. Consider it because it does the same job with a different approach (open source + cloud).
- Beacon (Open source): An open-source memory layer that captures traces from coding agents across harnesses and turns them into self-improving memory and visibility into what your agents did. Consider it because it also covers tracing and observability.
- Pixeltable (Open source + cloud): Multimodal data layer that combines storage, transforms, indexing and retrieval in one Python library for building agents over images, video and documents. Consider it because it also covers video and images and design.
- Headroom (Open source): Library, proxy and MCP server that compresses tool outputs, logs, files and RAG chunks locally before they reach the LLM, cutting tokens for coding agents. Consider it because it also covers MCP gateways and registries and MCP servers; it has more GitHub stars (75,629 vs 67,147).
- Chroma (Open source + cloud): Open-source search and vector database widely used for agent memory and RAG. Consider it because it also covers SQL and databases.
- MemOS (Open source): Memory operating system for LLMs and agents with persistent memory and retrieval. Consider it because it does the same job with a different approach (open source).
