Introducing Offline's most requested feature has finally come: an offline, local-first IDE.
Send us your code in three easy steps.
1) Download the code evaluation form. It's ironic that you need an internet connection for this.
2) Print out the form and write your code. Just tell us what language you're coding in and start hacking away.
3) Mail it to us and we'll run your code. It's as easy as that. Zero dependencies.
