I’m doing offline-first apps at work and want to emphasize that you’re constraining yourself a lot trying to do this.
As mentioned, everything fast(ish) is using SQLite under the hood. If you don’t already know, SQLite has a limited set of types, and some funky defaults. How are you going to take this loosey-goosey typed data and store it in a backend database when you sync? What about foreign key constraints, etc., can you live without those? Some of the sync solutions don’t support enforcing them on the client.
Also, the SQLite query planner isn’t great in my experience, even when you’re only joining on ids/indexes.
Document databases seem more friendly/natural, but as mentioned indexeddb is slow.
I wish this looked at https://rxdb.info/ more. They have some posts that lead me to believe they have a good grasp on the issues in this space at least

Project mention: 6 years building Planning Poker Online: from a weekend project to 147K users (and 3 mistakes I had to fix) | dev.to | 2026-05-11
Back in 2019, Google Firebase was becoming very popular. I was especially interested in the real-time capabilities — they had just launched Firestore and I wanted to give it a try. I thought it would be fun to build a small tool for my team so we could do proper estimations.

We built Constellation — an open-source GraphQL engine written in Go that is a near drop-in replacement for Hasura Community Edition. It reads the same metadata, generates the same schema, and serves the same GraphQL API. In production it uses ~90% less memory than Hasura with comparable or better latency, before any dedicated performance work.
