No plan fits quite right?Email me if you'd like to use CoderPad, but are enterprise scale, a non-profit, or an educational entity, and we can work something out.

Features

• Write and execute Ruby, Python, Java, Javascript, and Coffeescript, with more languages on the way!
• Collaboratively edit and run code in realtime with up to eight simultaneous participants.
• No friction for people you invite to collaborate, only the pad creator needs to sign up.
• All code execution happens right in the browser, so you get instant feedback about code correctness without waiting for a server to respond.

FAQ

• Is CoderPad secure? Can other people run code on my computer?

  Each collaborator in a pad is siloed off from all other participants. Code is evaluated on only one browser, and the results are sent to the other participants. All code execution is firmly sandboxed in a JavaScript interpreter or VM.

• What counts as a pad towards my quota?

  A pad will count against your quota if two or more participants join.

About

CoderPad was born out of my frustration with current etherpad-like tools, which only let me see if candidates knew how to write text that resembled code. When it came time to evaluate whether their solutions were correct, the people who fared best were those that could emulate the computer perfectly in their heads.

I found that many applicants with strong algorithmic and design intuitions fared poorly at catching missing parentheses or edge cases that were obvious in retrospect. Likewise, some candidates who were great at writing “whiteboard” code, turned out to not be able to code effectively in the office when brought on for an on-site interview.

CoderPad aims to sidestep these problems by providing a more realistic programming environment, that more accurately mimics how a candidate might program at her day job. I’ve found this helps tremendously with initial filtering, and I hope you find it just as useful.
