Brainy is the open vector+graph
database for intelligent applications
Legacy data tools weren't built for modern AI. Brainy combines vector search, graph reasoning, and streaming data in one portable package.
What Brainy Does
The database for AI-native applications.
MCP-Enabled
External AI models can access and invoke augmentations as tools through the Model Context Protocol.
Cross-Environment
Runs in browser, Node.js, containers—no setup friction. Deploy anywhere, scale everywhere.
Graph + Vector Native
Model your world with relationships and embeddings. Connect semantic similarity with structured relationships.
Streaming + Sync
Handle data in motion with WebSocket/WebRTC. Real-time updates, collaborative editing, live queries.
Fully Extensible
Pluggable embeddings, storage adapters, and distance functions. Bring your own models and backends.
Open Value
MIT licensed. No usage restrictions. No lock-in. Own your data, own your stack, own your future.
Why It Matters
Brainy was built for portability, extensibility, and open use. It's what we needed to power real-time, graph-aware applications across client and server.
