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.
Qdrant
Qdrant
Open-source, high-performance Rust vector database and search engine for scalable vector similarity search with advanced filtering and APIs.
Key features
- Vector Storage and Management: Stores high-dimensional vectors (points) alongside arbitrary JSON payloads, enabling combined similarity search and structured filtering on metadata.
- High-Performance Search Engine: Implements optimized nearest-neighbor search algorithms and data structures to deliver low-latency similarity search at large scale for production workloads.
- Extended Filtering and Faceted Search: Supports complex payload filters and faceted queries so semantic vector matches can be constrained by structured attributes (e.g., category, date, tags).
- Convenient APIs and SDKs: Provides REST and gRPC APIs plus official client SDKs (Python, TypeScript, etc.) for easy integration into applications and pipelines.
- Open-Source and Extensible: Distributed under Apache-2.0 license with public GitHub repositories, enabling self-hosting, modification, and community contributions.
- Managed Cloud and Enterprise Options: Available as a managed cloud service and has enterprise-focused deployments and support for production readiness.
- MCP Integration: Official Model Context Protocol (MCP) server implementation and tooling to integrate Qdrant as a context store for model-driven applications.
- Vector similarity search with payload filtering
- High RPS and low latency written in Rust
- Compression and disk offload to reduce memory usage
- Managed Qdrant Cloud with autoscaling and backups
- Deployable on AWS, GCP, Azure or on-premises
- High-performance vector similarity search engine implemented in Rust
- REST API for storing, searching, and managing points (vectors + payload)
- gRPC API support for high-performance integrations
- Extended payload filtering and faceted search capabilities
- Official SDKs and clients (notably Python and TypeScript/JavaScript shown in repos)
- Open-source Apache-2.0 licensed core with managed cloud and on-prem options
- Deployment examples and integrations (Kubernetes operator, Azure example repositories)
- Model Context Protocol (MCP) server implementation available in repos
- Examples, tutorials, and benchmarking tools available in official repositories
Best for
- Semantic Search: Replace keyword search by embedding documents and performing nearest-neighbor queries to retrieve semantically relevant documents or passages.
- Retrieval-Augmented Generation (RAG): Use Qdrant as the vector store to fetch context passages for LLM prompts, improving factuality and relevance of generated responses.
- Recommendation Systems: Match users and items by embedding profiles or content and performing similarity searches combined with attribute filters for personalized recommendations.
- Multimodal Search: Index image, audio, or multimodal embeddings to enable reverse-image search or cross-modal retrieval with semantic similarity.
- Faceted Content Discovery: Combine vector similarity with structured payload filters (e.g., category, date range, tags) to build refined, faceted search experiences.
- Enterprise Vector Storage: Operate as a production-grade vector database for on-premise or cloud-managed deployments with support for scaling and operational tooling.
