DevPod
Codespaces but open-source, client-only and unopinionated
...You can think of DevPod as the glue that connects your local IDE to a machine that you want to develop. So depending on the requirements of your project, you can either create a workspace locally on the computer, on a beefy cloud machine with many GPUs, or a spare remote computer. Within DevPod, every workspace is managed the same way, which also makes it easy to switch between workspaces that might be hosted somewhere else.
