AkitaOnRails

Free

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.

  • Automated customer communications: Chatbots and support agents trigger personalized follow-up emails or support responses programmatically from conversation context.
  • Workflow automation for product events: Product automation pipelines use LLMs to generate tailored messages and dispatch them on user triggers (signup, churn signals, billing events).
  • Integrating agents with delivery controls: Teams deploy the MCP server to let models send emails while maintaining sending domain configuration and contact list management for deliverability compliance.
  • Developer and testing environments: Developers use the open-source MCP server to prototype AI-agent email features and validate end-to-end model-to-inbox behavior.
  • Automated transactional notifications from SaaS apps
  • Product update and marketing email campaigns
  • Letting LLMs compose and send emails via MCP integration
  • Integrating email sends into application workflows via API
  • Centralized email delivery and deliverability monitoring for SaaS
