- Supermemory (Open source + cloud): Memory and context engine for agents with an API, app and MCP server, which can also run fully locally. Consider it because it also covers MCP servers.
- EverOS (Open source): Local-first, portable memory layer for AI agents stored as Markdown. Consider it because it does the same job with a different approach (open source).
- xerj (Open source): A local-first search engine and MCP server for agents: one Rust binary indexes code, docs, logs, CSV/JSONL and PDFs for full-text, vector and hybrid search plus agent memory, behind an Elasticsearch-compatible API. Consider it because it also covers RAG and documents and search APIs.
- LongMemory (Open source): Local-first memory engine for agents that keeps durable, time-aware memories in SQLite and serves them to Claude, Copilot, Codex and others over MCP, CLI or HTTP. Consider it because it also covers terminal and CLI agents.
- projectmem (Open source): A local-first memory layer for coding agents that records issues, attempts, fixes and decisions and warns your agent before it repeats a past mistake. Consider it because it does the same job with a different approach (open source).
- Basic Memory (Open source + cloud): Persistent memory for Claude, Codex and Cursor stored as local Markdown knowledge, available open source or as a hosted cloud workspace. Consider it because it is ready to use without building anything.
- Graphicle (Open source): Graphicle, from KarLex AI, is a single local Rust program that gives Claude Code, Cursor, Codex and other MCP agents a code graph and memory, returning excerpts with file and line references from your code, docs and past sessions, with no account or telemetry. Consider it because it does the same job with a different approach (open source).
- Claude-Mem (Open source): Gives coding agents memory across sessions by capturing what they do, compressing it and feeding the relevant context back in later. Consider it because it has more GitHub stars (101,230 vs 59,622).
- 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 RAG and documents and MCP gateways and registries; it has more GitHub stars (75,629 vs 59,622).
- Mem0 (Open source + cloud): 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. Consider it because it also covers RAG and documents and scraping and crawling; it has more GitHub stars (67,147 vs 59,622).
