Got questions?
Here are the answers to the ones we hear most often.
Where can I send feedback?
You can send feedback through this form.
Can I use it with more than one friend?
Yes. Small groups are supported, although very large rooms may still surface edge cases while the project is young.
The extension doesn't work on a site. What should I do?
Refresh the page first. If it still fails, tell us about the site and we will investigate.
How can I support the project?
Share Synclify with friends, or help cover running costs through GitHub Sponsors.
How can I contribute to development?
Both the extension and backend are open-source. Browse the GitHub repository and jump in wherever you can help.
