Description

Craft your backend as if it were a Flutter application, effortlessly deploying it with a touch of brilliance. Celest serves as a cloud platform specifically designed for Flutter developers, allowing them to construct, deploy, and oversee backends using Dart exclusively. By simply annotating any Dart function with the cloud tag, developers can convert it into a serverless function, which enhances backend logic integration within the Flutter framework. Celest works harmoniously with Drift schemas, which means it automatically generates databases, making data management much more straightforward. The deployment process is streamlined and requires only a single command, which sets up Celest, migrates the project, warms up the necessary engines, and launches it in the Celest cloud, resulting in a live project URL. The platform boasts an array of features including Dart cloud functions, server-side Flutter applications, upcoming server-side widgets, hot reload capabilities, auto-serialization, and client generation. By prioritizing the development experience, Celest aims to empower Flutter developers to create more efficiently and effectively. Overall, Celest represents a significant advancement in how Flutter developers can manage their projects in the cloud.
