BetterTyped

BetterTyped is a developer tool that creates type-safe API layers for TypeScript applications. It generates fully typed SDKs from OpenAPI or Swagger specifications, eliminating the need to write manual API client code. The tool supports multiple protocols including REST, GraphQL, Firebase, WebSockets, and Server-Sent Events, all through a consistent interface that provides complete TypeScript type safety from parameters to responses.

What makes BetterTyped stand out is its comprehensive approach to API management. Instead of juggling separate libraries for fetching, caching, retries, and real-time updates, developers get one integrated system. The tool includes a production-ready data layer with built-in caching, request queuing, automatic retries, deduplication, and offline replay capabilities. For React developers, it provides ready-to-use hooks like useFetch and useSubmit that handle loading states, errors, and data management automatically.

This tool benefits developers building complex applications that interact with multiple API endpoints or protocols. It's particularly useful for teams maintaining large codebases where API changes can break frontend code. By generating type-safe SDKs from API specifications, BetterTyped catches mismatches at compile time rather than runtime. Real-world use cases include migrating legacy API clients to TypeScript, unifying data fetching across REST and WebSocket connections, and providing AI agents with typed contracts for reliable API interactions.
