The first method is recommended.
- Glitch projects are essentially git repos if you haven’t heard so you can clone one of them and push to remote to upload changes.You can open your ide in the folder to make changes.
This method is overcomplicated and might spam the git with lots of commit requests
- In macos/ubuntu you can mount a git repo as an FUSE file system using https://github.com/PressLabs/gitfs
I might work on an app that allows you to have a folder in the drive for each glitch project for easy access. But working with the glitch api is difficult and not supported.
