Turn functions into APIs with one line of code

Encore.ts generates the communication boilerplate and ensures full type-safety.


Learn how to define APIs in Encore with this introduction app:
$ encore app create --example=ts/introduction

Integrate infrastructure as type-safe objects in application code

Encore makes your infrastructure type-aware and removes the need for connection strings and other boilerplate in your application.


Deploy anywhere that supports Docker images using Encore's Open Source tools.
