Hydro is a high-performance online judge system.
It is easy to deploy (with install script), light weight and extensible.
Also see previous version at vijos/vj4

Now we have a SaaS service running at https://hydro.ac. (Fully free of charge!)
You can easily have a glance at the features of the system and try it out.
You can also just use the service without self-hosting the system with the powerful domain feature.
Feel free to create an account and then navigate to MyAccount > MyDomains > Create Domain to create one.
