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 the https://riju.codes!

Riju will always be free for everyone. I pay for the hosting costs myself.

A number of people have asked me if they can donate to help keep Riju online. In response, I have set up a Patreon page where you can contribute. All donations will be used solely to cover hosting costs, and any surplus will be donated to the Electronic Frontier Foundation.

Riju does not collect your personal information.

• Your code is deleted from the server as soon as you close Riju.
• Your terminal input and output is never saved or logged anywhere.
• Riju uses Fathom Analytics to measure traffic. Fathom collects very limited data and does not sell it to third parties, unlike Google Analytics.
• Riju does not serve advertisements or share data with any third party aside from Fathom Analytics.

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.

Yes, there is one rule and it is "please be nice". Examples of not being nice include:

• Trying to consume as many resources as possible. All this will do is prevent others from using Riju, which isn't nice.
• Mining cryptocurrency. Since hosting Riju comes out of my paycheck, this is exactly equivalent to stealing, which isn't nice.

Absolutely, please see Contributing guide.
