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.

- Transfer API: initiate and manage money transfers (Quickstart and Transfer SDKs)
- Webhooks: notify applications of item and transaction changes to avoid polling
- Sandbox and testing endpoints (e.g., sandboxItemResetLogin) for development and QA
- Client libraries and sample apps (Quickstart, Pattern demos) in multiple languages
- Request/session identifiers (request_id, link_session_id) in responses for logging and troubleshooting
Best for
- Customer Onboarding and Account Verification: Use Plaid Link and the Auth/Identity APIs to quickly verify bank account ownership and identity during sign-up or KYC flows.
- Personal Finance Management Apps: Integrate the Transactions API and webhooks to ingest and keep users' transaction histories up to date for budgeting, categorization, and insights.
- Payment & Account Funding Flows: Implement ACH-based payment initiation and account funding using Plaid's Transfer APIs and sample quickstart apps to handle end-to-end payment flows.
- Lending and Underwriting: Pull account balances and transaction histories to assess cash flow, verify income and improve automated underwriting decisions for loans.
- Fraud Reduction and Risk Monitoring: Use identity verification, account linking validation, and transaction signals to detect anomalous behavior and reduce fraud in financial workflows.
- Payroll and Payroll Deposit Setup: Verify direct deposit accounts and confirm routing/account details using Auth and Balance endpoints to streamline payroll setup.
- Developer Prototyping and Testing: Leverage Plaid's sandbox, quickstart repositories, and client libraries to build, test, and iterate integrations before going to production.
