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.

pumaDB
pumaDB
Durable JSON memory API for agents that stores and serves agent memory via hosted MCP or REST without requiring database setup.
Key features
- Hosted MCP Endpoint: Provides a managed MCP interface so agents can connect to a memory control plane without self-hosting infrastructure or managing databases.
- REST API Compatibility: Offers a standard REST API for inserting, querying, and retrieving JSON memory rows from existing services and agent frameworks.
- Durable JSON Row Storage: Persists structured JSON rows as durable memory entries, enabling stateful behavior across agent sessions and long-lived context retention.
- Memory Review and Inspection: Includes capabilities to review stored memories so developers and auditors can inspect agent state and historical interactions.
- No-Database Setup: Eliminates the need to provision, configure, or maintain a dedicated database project — simplifying prototyping and production deployment.
- Lightweight Integration: Designed for quick integration with agent systems and assistants, reducing engineering overhead to add persistent memory.
- Hosted MCP and REST endpoints for integrations
- Store arbitrary JSON rows as durable memory
- Durable agent memory without a separate database project
- Review and retrieve persisted agent memory
- Simple API surface to connect agents to persistent storage
Best for
- Persistent Conversational Context: Store user preferences and past conversation turns as JSON so chatbots can recall history across sessions.
- Stateful Autonomous Agents: Provide long-term memory for agents that require recall of decisions, tasks, and learned information over time.
- Rapid Prototyping without DB Work: Enable developers to build and test memory-enabled agents without provisioning or maintaining database infrastructure.
- Audit and Debugging of Agent Behavior: Review stored memory entries to trace agent reasoning, reproduce issues, and validate decision contexts.
- Cross-Service Memory Sharing: Use REST or MCP interfaces to share agent memory between microservices, chat platforms, and orchestration layers.
- User Profile Management for Assistants: Persist structured user data (preferences, settings, history) as JSON to personalize assistant responses.
- Maintain long-term memory for conversational agents
- Persist agent state and interaction history as JSON
- Enable stateless agents to access shared durable memory across sessions
- Prototype agents quickly without managing database infrastructure
