Congrats! The world needs more local-first software, but many find a complete switch hard and practically impossible, so reusing existing Postgres DB is an excellent idea. I suppose there is a space for more solutions; that's why Evolu takes a more radical and clean approach with complete privacy by default without opt-out. Also, a dependency on third-party servers should be limited as much as possible, so that's why Evolu Server is super simple and generic for all Evolu clients. Another Evolu feature is the simplicity of the code. CRDT shouldn't be a black box only people with Ph.D. can understand. So, if anyone is interested in another approach, check https://github.com/evoluhq/evolu.
