SDKs & Client Libraries

Status: The TypeScript and Dart/Flutter SDKs are the main documented client SDKs today. The Rust SDK is available as a beta source package, and the Python SDK is still in development.

KalamDB currently has two primary SDK tracks, one source-first client, and one upcoming SDK:

• TypeScript SDK for browser/Node.js apps and worker services
• Dart / Flutter SDK for mobile and cross-platform app clients
• Rust SDK for native async Rust services and topic workers
• Python SDK (Coming Soon) for Python services and tooling

Which One To Start With

• Building frontend + backend JS/TS apps: start at TypeScript Setup
• Building Dart/Flutter apps: start at Dart Setup
• Building Rust workers/services: start at Rust SDK
• Building Python services today: use HTTP API Reference until the SDK ships

Shared Concepts Across SDKs

• JWT bearer auth for SQL and realtime flows
• SQL execution over /v1/api/sql
• WebSocket realtime subscriptions over /v1/ws
• Topic consume/ack for worker processing
• Vector search through regular SQL (EMBEDDING, COSINE_DISTANCE, and indexed queries)
