Can I sell a product that runs on Trello?

Hi I am trying to flip my business online (like everybody else) and I see that people have ‘planners for trello’ and ‘content plans for trello’ and ‘funnels for trello’ and so on.

If I was to do similar Do i need permission from trello to do this?

Thanks

I don’t think that you need explicit permission.

However, the developer terms do apply: https://developer.atlassian.com/cloud/trello/developer-terms/
