Marmot: Multi-writer distributed SQLite based on NATS
Also Expensify's Bedrock, which powers their famous "Scaling SQLite to 4M QPS" article:

SQLite is not a toy database
Lots of things don't need failover, but if you do, you can use Bedrock, which is built on sqlite.

Ask HN: Hunting for a Framework
Vapor[0] based on Swift. Advantage of this is that you don't have to evaluate multiple frameworks for Swift and suffer paralysis by analysis. All the Swift community is behind one framework.
The next is Actix[1] based on Rust. There are many frameworks in Rust and most of them have not reached 1.0 And which framework will survive becomes a question.
Other not so well-known is Wt[2] based on C++. This actually is created for programmers who are not web developers. The development experience is similar to desktop app development like Qt.
If that is not acceptable then Django[3], based on Python, is the one that will be good for you.
For the front-end I would recommend Flutter[4]. As much as I dislike getting tied to a single company for whom the framework is not their bread-and-butter, I don't see any other viable options to Flutter that will cover all web, mobile and desktop out of the box.
For databases, I would recommend BedrockDB[5], if you are not averse to SQLite. Or FoundationDB[6], if you want NoSQL. But if you are not concerned about horizontal scalability or okay with self-managing database availability, then PostgreSQL[7] is a very good option.
For push notifications, PushPin[8] is a good option.

Databases: 2021 in Review and Predictions for 2022
Recently I stumbled upon BedrockDB[0] from Expensify. It is based on SQLite and has very interesting idea on HA and distributed DB.

One million queries per second with MySQL
This is not SQLite though, also the test is trivial compared to TPC: https://github.com/Expensify/Bedrock/blob/dbarrett_perftest/...

Turning SQLite into a Distributed Database
Don’t forget BedrockDB (built on SQLite) that’s used in production at Expensify.
How it scales as well.

Building for the 99% Developers
Instead of just continuously firing off questions when you acknowledge you’re not even reading the articles linked too … nonetheless, bedrockdb has replication and failover.
