How does exe.dev measure disk usage?

We look at the filesystem usage of your ext4 filesystem. If you have a VM with a disk of 25 GB, the most disk usage that this could use is 25 GB, but less is very likely.

exe.dev will occasionally run fstrim or equivalent to all our infrastructure to reclaim your free space.

The default exeuntu is about 4 GB in size. We think a "batteries included" image is a great default, but if you are optimizing for space, you can build your own smaller image with the tools you require.
