# How do I build an app for my organization to use internally?

Stripe apps are built using [React](https://reactjs.org/), [TypeScript](https://www.typescriptlang.org/), and our own [UI and client-side libraries](https://stripe.com/docs/libraries). The [setup process](https://stripe.com/docs/stripe-apps/getting-started) is quick and simple for developers.
Once the app is built, you can [upload it](https://stripe.com/docs/stripe-apps/upload-app) to your account where it will be available to use in the dashboard.
