One of those I've tried is LiteDB - https://github.com/mbdavid/LiteDB https://github.com/mbdavid/LiteDB. I liked it. It's small yet capable. If you are familiar with MongoDB, you will feel right at home. It's great for .NET developers as it's written in C# but since it's Netstandard 1.3 compatible, you can presumably run it under Ubuntu or Mac OS or wherever else the new .NET 5 runtime works. I've got a C# app running on ARM64 the other day - just saying. I wrote about my experience playing with LiteDB here - https://tomaskohl.com/code/2020-04-07/trying-out-litedb/ https://tomaskohl.com/code/2020-04-07/trying-out-litedb/. It's not an in-depth look at all, just a few notes from the field, so to speak.
