Score: 8.0/10 (Innovation: 8, Technical: 9, Documentation: 8, Utility: 7)

Bitsql is a memory-only SQL Server emulator written in MoonBit that speaks TDS, allowing tedious/mssql clients to connect. It aims to replace the heavy SQL Server container in CI with a 40 MB image that starts in 0.22s and uses ~5 MB RAM, while maintaining compatibility with common SQL features and even formally verifying core arithmetic.

Target audience: backend devs, devops, test engineers
