I am looking for open source and (free for small teams up 15 people) issue/bug tracker, that has following features:
- Web based
- Ability to copy/paste images from clipboard (like in GitHub issues, GitLab issues, Jira, GMail, etc.)
- Email notification (new issues, changes, comments, etc.)
- Multiple assignee (or "CC List" like in Bugzilla)
- Some classification (like in Bugzilla) or tags/labels (like in GitHub)
- Deadlines
- File attachments
Nice to have features:
- Integrated wiki, forums, etc.
- Email Reports (for example - deadlines)
- Custom fields
- Some text formatting (like Markdown)
Notes:
- Bugzilla, Trac, Mantis almost fit, but they don't have copy/paste images feature
- GitLab issues almost fits, but there is no multiple assignee feature
- GitHub issues fits, but no free version
- Jira fits, but no free version
