Thanks to Raku community’s members @AlexDaniel and @rba who supported the idea of bringing RakuDist to community infrastructure, so long story short:
https://rakudist.raku.org is available!
Check the service out to test your Raku distribution against various versions of Rakudo. Ubuntu and Debian OS are available.
The service is in beta stage, feel free to post bugs or suggestions to RakuDist GitHub project.
Here is also API docs if you prefer programmatic interface instead of launching tests through a web form.
Thanks for reading.
