# Mem0 Mem0 is a self-hosted ai app. Self-hosted memory server for AI coding assistants. It is open source and self-hosted, installable on Unraid. Canonical page: https://ourlocalhost.com/app/3046/mem0 ## Description Self-hosted memory server for AI coding assistants. Store, search, and manage persistent context across sessions so your tools remember what happened last week without stuffing everything into the context window. Each project gets its own isolated vector collection with automatic fact extraction, deduplication, and semantic search. Works with Claude Code, Cursor, Windsurf, and any MCP-compatible client. Includes a bundled LLM for zero-config operation, or connect to Ollama or OpenAI for better quality. Web dashboard included for browsing and managing memories. ## Platform availability Available on 1 of 9 platforms: Unraid. ## Health score 71/100 (Good), based on 4 of 5 factors. - Maintained: 100 (last commit 4 days ago) - Popular: 97 (67,021 GitHub stars) - Easy to install: 35 (1 install platform, install notes, Docker image) - Security check: 15 (2 serious findings, 6 minor, CI, tests) ## Security check 2 serious findings: Uses anyio 4.9.0, which has a known critical vulnerability; Uses chromadb 1.5.9, which has a known critical vulnerability.

The self-hosting guide describes a three-container Docker stack: API, Postgres with pgvector, and Neo4j. ### Can I use local LLMs with the self-hosted Mem-zero deployment? Yes, the Docker self-hosting guide says you can swap in local LLMs while keeping conversation data on your own infrastructure. ### Does the self-hosted Mem-zero bundle include a web dashboard? Yes, the self-hosted bundle ships the REST API and a web dashboard together. ### Does Mem-zero keep persistent context out of the context window? It stores, searches, and manages persistent context across sessions instead of filling the context window. ## Alternatives - Claude Memory: Long-term memory for Claude AI. - Claude-Mem: A Claude Code plugin that automatically captures everything Claude does during your coding sessions, compresses it with AI (using Claude's… - Contextify: Your Claude Code history deletes after 30 days. - Engram Alpha: A local-first, open-source long-term graph memory engine for AI agents and developers that actively fights knowledge drift and eliminates c… - Mnemosyne OS: A control room for AI memory. - Tolaria: Desktop app for large markdown knowledge bases, using plain files, Git versioning, YAML frontmatter, offline use, open source, and Claude C… - Tracebrain --- Source: Our Local Host (https://ourlocalhost.com/app/3046/mem0), the self-hosted and open-source app directory.
