Is there a front-end sgf editor that support go problem solving?

Is there an open source sgf editor that can be used to make a go problem web app?

I want to make one for my local club to solve daily tsumego.

It should be able to detect successful/failed attempt to keep record/provide feedback, and also it would be best if it’s open source (so I can localize it, not all of my club member know English).

Can anyone help me? :smiley:

Thank you very much, but is there something like an API for it? I can’t find it anywhere…
How do I detect when an user made an attempt and whether it’s a success or not?

I don’t know, I just remember from a long time ago that it has a problem solving mode.

EDIT: Oops it doesn’t seem to have a problem mode. You could add one to it though :slight_smile:

This seems to be a new project, but it looks promising
