The only AI SDK you need. Multi-agent orchestration, streaming execution, RLHF instrumentation, safety guardrails, and encrypted database - all in one framework-agnostic platform.
Documentation • Examples • API Reference • Discord • Website
Every other AI SDK gives you streaming and function calling. That's table stakes.
AI Kit gives you what you actually need in production:
- Streaming Transports - Production-ready SSE, WebSocket, and HTTP transports with automatic reconnection (v0.2.0)
- Agent Swarms - Coordinate multiple AI agents with supervisor pattern (no competitor has this)
- Auto-RLHF - Capture every interaction for model improvement without code changes
- Intelligent Memory - Stores facts with contradiction detection and auto-consolidation
- Enterprise Safety - Prompt injection detection, content moderation, PII handling (7 attack patterns blocked)
- Video Recording - Built-in screen recording, camera access, and media processing primitives (v0.2.0)
- CDN Distribution - Global edge delivery via jsDelivr & unpkg (~1KB gzipped core)
- Cost Tracking - Real-time token counting and cost calculation across providers
- ZeroDB Native - Encrypted database with vector search, built-in
- Framework Agnostic - React, Vue, Svelte, vanilla JS - works everywhere
- Complete Tracing - Every execution step traced with full context
- Mobile-First - Comprehensive mobile device testing (292 tests, 7 device profiles)
