I have done a little more reading and it appears that one fundamental difference between InstantDB and ElectricSQL is that InstantDB does not sync with standard PostgreSQL tables. ElectricSQL does.
If that understanding is correct, then InstantDB may be a good fit if you are starting your database from scratch or can completely get rid of your existing one.
I have more than 170GBs of data in a SQL database. I can sync parts of it to ElectricSQL using shaped queries.
We're working on a feature where you bring an existing Postgres database, and use Instant as the sync layer [1]. If you have an app like this and would be interested in beta testing, let us know: founders@instantdb.com
