Sarah & Joe: Thank you both so much for this - Joe for the contribution and Sarah for the thorough write-up!

Joe's comment is spot-on. There will always be a free plan. Like all freemium models, the free plan will have limited features and access, of course.

Joe's also correct in saying we have a Free-for-open-source program. So long as the project you're testing is open source, you can have a full featured license to Tenon.

Finally, we're very interested in working with people who create stuff with Tenon or integrate Tenon into other stuff and can come up with special plans for them.
