CodeNotes

 Simple

You need only GitHub account and at least one repository in it to use CodeNotes.
No setup or registration required!

 Productive

We are here to improve your development experience. With CodeNotes you don't need to use Jira, YouTrack or RedMine and interrupt your flow — just write comments and push, that's all.

 Modern

CodeNotes is designed from the ground up to be as streamlined as possible. Our goal is to deliver realtime reactive experience. Websockets, GitHub push hook support, asynchronous IO, you name it.
...and it is free!
