I also like the fact that snap is Free software - I'm still not able to find out from the scratch 3.0 website if scratch can be easily self-hosted, modified etc

I also like the fact that snap is Free software - I'm still not able to find out from the scratch 3.0 website if scratch can be easily self-hosted, modified etc? Snap is on github: https://github.com/jmoenig/Snap https://github.com/jmoenig/Snap It also is based around js, and can import scratch 2.0 sketches (not sure how well that works in practice) - I wonder if there's any collaboration with MIT scratch moving off of flash to js - or if they did everything from, well, scratch ?
