Reporting Bugs

We are using GitHub Issues for our public bugs. We keep a close eye on this and try to make it clear when we have an internal fix in progress. Before filing a new task, try to make sure your problem doesn't already exist.

If you found a bug, please report it, as far as possible with:

  • a detailed explanation of steps to reproduce the error
  • a browser and the browser version used
  • a dev tools console exception stack trace (if it is available)

If you found a bug that you consider better discuss in private (for example: security bugs), consider first send an email to

We don't have formal bug bounty program for security reports; this is an open source application and your contribution will be recognized in the changelog.

Pull requests

If you want propose a change or bug fix with the Pull-Request system firstly you should carefully read the DCO section and format your commits accordingly.

If you intend to fix a bug it's fine to submit a pull request right away but we still recommend to file an issue detailing what you're fixing. This is helpful in case we don't accept that specific fix but want to keep track of the issue.

If you want to implement or start working in a new feature, please open a question / discussion issue for it. No pull-request will be accepted without previous chat about the changes, independently if it is a new feature, already planned feature or small quick win.

If is going to be your first pull request, You can learn how from this free video series:

We will use the easy fix mark for tag for indicate issues that are easy for beginners.
