Great work! I'm working on my own boilerplate around firestore / EQL for exactly the same use case. Will definitely consider Biff for the next app, as I imagine it will be much more cost-effective then firebase after free tier. 🙂

Thanks! You might be interested in this by the way: https://github.com/jacobobryant/trident/blob/master/doc/firestore.md I wouldn't plan on Biff beating Firebase on price anytime soon--I'm already paying $25/mo with Biff now ($10 for the droplet and $15 for managed postgres to back Crux), vs pennies when I was on Firebase. But I've loved having a JVM backend, and having total control over everything.

Thanks for sharing. I'll check it out. Yes, for some projects you want to have some back-end and cloud functions just don't cut it for all the use cases.
