# Overview

> Use iroh from Rust, Python, Swift, Kotlin, or JavaScript.

iroh is available in Rust, Python, Swift, Kotlin, and JavaScript. Pick the language that fits your app and follow its guide to get a working endpoint in minutes.

| Language                            | Status   | Platform notes         |
| ----------------------------------- | -------- | ---------------------- |
| [Rust](/languages/rust)             | Official | Primary implementation |
| [Python](/languages/python)         | Official | Prebuilt wheels        |
| [Swift](/languages/swift)           | Official | iOS + macOS            |
| [Kotlin](/languages/kotlin)         | Official | JVM + Android          |
| [JavaScript](/languages/javascript) | Official | Node.js via N-API      |

All five official bindings share the same basic API surface for sending streams
or datagrams over QUIC.  The Rust language bindings are the most complete and
up-to-date, and contain custom configuration and protocol features.

  One demo, four languages: SwiftUI and Jetpack Compose apps plus Python and Node console readers, all speaking the same protocol over iroh. A good starting point for any of the bindings.

  Get in touch and tell us what you're building. We can prioritize new bindings or help you maintain your own.

## Build your own wrapper

If you're comfortable with a little bit of Rust, you can write your own wrapper
around iroh, a small application-specific binary that exposes functionality over
a local HTTP server or daemon, or a full FFI wrapper from Rust to your target
language. Either way, this gives you:

* Full control over the API surface you expose
* The ability to tailor it to your specific use case
* Type-safe bindings for your language (with FFI)
* Calls from any language (with an HTTP wrapper)

While it's easy to get a first version working, **ongoing maintenance and
testing is the hard part**. iroh is under active development, and keeping
wrappers up to date with new releases, testing across platforms, and handling
edge cases takes sustained effort. The [number0](https://n0.computer) team runs
a testing lab for this purpose. If you need help, [schedule a meeting](https://cal.com/team/number-0/iroh-services) or [contact us](/contact).

## WebAssembly and browsers

iroh compiles to WebAssembly for use in browsers. See [WebAssembly browser support](/languages/wasm-browser) for the constraints and a working browser-echo example.
