Hyperliquid TypeScript SDK vs Katoshi

The Hyperliquid TypeScript SDK is a comprehensive, community-maintained client library for the Hyperliquid API, supporting all major JavaScript runtimes including Node.js, Deno, Bun, and browser environments. Written in TypeScript with full type coverage, the SDK provides ergonomic abstractions for REST API calls and WebSocket subscriptions, making it easy to build Hyperliquid integrations in the web ecosystem. The library handles authentication, request signing, WebSocket reconnection logic, and response parsing—letting developers focus on business logic rather than protocol details. It supports the full Hyperliquid API surface including order management, account queries, market data streaming, and HyperEVM interactions. With active maintenance and growing adoption in the developer community, this SDK is the standard choice for frontend applications and Node.js trading systems interfacing with Hyperliquid, bridging the gap for JavaScript developers entering the ecosystem.
