I started out with the trial of Airtable and absolutely loved it. It is perfect for what I'm looking to do - but what I'm looking to do is a small, personal project, that being able to share Interfaces publicly is perfect for.
Now that my trial is over and I'm on the Free version, Airtable still covers everything I need - EXCEPT that specific part, and I unfortunately cannot justify $24/mth to go to the first paid tier. However, I would happily pay $5-6 a month to keep all the other features of a Free account and just add this specific functionality on.
