## Runtime type system

Why do you need Runtime and Static type system together? See [this discussion](https://github.com/gcanti/io-ts/issues/18).

### Compatible with TypeScript

* [ts-runtime](https://fabiandev.github.io/ts-runtime/) - TypeScript Runtime Type Checks Playground

* [io-ts](https://github.com/gcanti/io-ts) - TypeScript compatible runtime type system for IO validation

### Compatible with Flow

* [flow-runtime](https://codemix.github.io/flow-runtime/) - Flow-compatible runtime type system for JavaScript.

* [flow-io](https://github.com/gcanti/flow-io) - (deprecated) Flow compatible runtime type system for IO validation
