SQLite is a lightweight and simple database technology that is widely used due to its widespread adoption in various platforms, including Android phones, iPhones, browsers, Macs, and Windows machines. Its simplicity and low overhead make it suitable for testing purposes, allowing developers to spin up new databases for each test, run queries in isolation, and tear them down quickly without worrying about cleanup or state persistence. However, SQLite's differences from Postgres can lead to false confidence in tests, as SQL dialects, data types, and behavioral quirks can vary between implementations. Neon is a cloud-native Postgres solution that combines the simplicity of SQLite with the correctness and power of a real Postgres engine, offering features such as ephemeral branching, serverless architecture, and genuine Postgres performance characteristics, making it an attractive option for developers who want fast feedback loops without sacrificing production fidelity.
