I tried to learn Fauna and FQL a couple of years ago; their documentation was hard to trudge through with few examples, and their pricing was hard to grasp.
I think they also recently nerfed the free tier.
I've been using CouchDB and Pocketbase.io much more successfully for my mini web apps.
Pocketbase seems like fun; I had not heard of it before. Separate, but related: whenever I contemplate transitioning from a relational DB to something like CouchDB, or a similar option, to simplify the initial setup and SQL-related hassles, I inevitably realize that, as appealing as it sounds and as much as I'd love to, the challenges and limitations down the road become more apparent and I stick with SQL. I know this is obvious, but the choice really does heavily depend on your specific use case. SQL makes some simple things hard, but the reverse is also true :( I wonder if we'll reach a stage where we can get the advantages of both ¯ \ _ ( ツ ) _ / ¯
Getting the best of both worlds is what we're trying to achieve with Fauna, at least for OLTP use-cases. I'd be curious to hear what challenges with you ran into with other NoSQL databases, though.
