Overview
What is Celest?
Celest is a backend-as-a-service for Flutter developers that enables you to build your backend entirely in Dart. Build the use cases you need without any additional tooling or context switching to different programming languages. Since you are writing your backend in Dart, Celest enables you to share logic and code between your Flutter app and your backend.
How do I use Celest?
You primarily interact with Celest using the Celest CLI.
Once you download and install the CLI, run celest start from your Flutter project to create your celest folder. This will contain all of your backend logic. You can then use the Celest CLI to build your project locally and leverage the code-generated client in your Flutter app to connect to your backend. When you feel confident with your changes, use the CLI to deploy your backend to the cloud.
Celest offers a set of use cases via "Cloud Widgets," constructs that encapsulate groups of functionality. Using these widgets you can declaratively define your backend features such as Authentication, Data, and Storage.
What can I build with Celest?
At a high level, the following "Cloud Widgets" are available for you when building with Celest.
Note: We will be rolling out new features and functionality over the coming months. If there's a use case you'd like to see which isn't listed here, please let us know by creating an issue (opens in a new tab) in our GitHub repo or chatting with us on Discord (opens in a new tab).
| Features | Description |
