Riju is a very fast online playground for every programming language. In less than a second, you can start playing with a Python interpreter or compiling INTERCAL code.
Check it out at https://riju.codes! Please note that Riju is only available on IPv6-enabled networks due to the higher financial cost of supporting legacy protocols. If your network does not support IPv6 then please consider asking your network administrator or service provider to do their part in supporting modern internet standards. You can consider accessing Riju through a VPN as a workaround.
Service uptime available at https://radian.statuspage.io/.
Riju will always be free for everyone. I pay for the hosting costs out of the business account of Radian LLC, which is funded by donations and my personal savings. If you would like to help keep Riju online and see more projects like it, there are a few donation methods available in the "Sponsor this project" sidebar on GitHub.
All financial records for Radian LLC are made publicly available.
Riju does not collect your personal information.
All of the above notwithstanding, any service that allows people to run code online is inherently risky. For this reason, I can't make any guarantees about the security or privacy of your data.
