### For Web Apps

At Alby we build on open standards. Alby exposes a number of javascript objects to the browser, which can be used to interact with bitcoin on-chain (WebBTC), bitcoin lightning (WebLN), Nostr, Liquid, and more.

### For Web and Mobile Apps

If you want to power your web or mobile app with bitcoin and want to offer payments directly in the app, have a look at the [Alby NWC Wallet API](https://app.gitbook.com/o/uiUeRqI074apbV0PWsyf/s/HyuCj8CH0AbFLyvhXAEx/). It allows native payment experiences for users. As a web and mobile developer, you can entirely focus on your app. Alby covers your back and does the payment processing for you.

Have a look at the Alby NWC Wallet API documentation:
