ai-memory
AkitaOnRails
Open-source, self-hosted long-term memory server that lets Claude Code, Codex, Cursor and other agent CLIs share context and hand off sessions.
Key features
- Cross-Agent Handoffs: Typed, claim-once handoffs let you continue a session in a different agent CLI.
- Automatic Capture: Lifecycle hooks record prompts, tool calls and session boundaries, sanitized before storage.
- Markdown Wiki Storage: Git-backed wiki of .md files is the source of truth, with a rebuildable derived database index.
- Multi-Mode Search: Full-text, entity and graph search plus optional vector search.
- Team Sharing: Per-project knowledge sharing with multi-user auth, per-person attribution and an audit log.
- Self-Hosted Single Binary: Rust binary or Docker server running on your laptop, homelab or LAN host.
- Zero-LLM Default: Capture and search work without an LLM API key.
- Broad Agent Support: Works with Claude Code, Codex, Cursor, Gemini CLI, OpenCode, Kiro CLI, Grok Build CLI and more.
Best for
- A developer starts a feature in Claude Code and continues it in Codex without re-explaining the project.
- A team shares project knowledge across members' coding agents with an audit trail.
- An engineer keeps memory on a homelab server so every laptop and agent sees the same context.
- A privacy-focused user runs fully local memory capture with no LLM calls or cloud service.
- A maintainer browses and edits agent memories as plain markdown in a git repository.
- A developer onboards a new agent CLI to an existing project through MCP install commands.
