Introduction
Clace is an open-source Apache-2.0 licensed project building a platform to easily develop and deploy self-hosted web applications. The main repository for Clace source code is clace. This repository has the source for Clace app template specs, which can be used as spec argument during app initialization. For example, --spec python-flask. See here for details.
App specs allow for existing applications to be used with Clace with no changes required in the application code. Pass the --spec option during app create. Clace will include the template files from the spec and bring up the application. If the spec uses containers (most do, proxy spec is the exception), then Clace will download the source code, add the template spec files, build the image and start a container with that image. API calls are automatically proxied to the application within the container.
