Hello.
I’m building an experimental server that’s wire-compatible with mongod, and translates MongoDB commands to SQL to enable you to use SQLite as a JSON database. You can connect to it with existing MongoDB clients and language drivers.
It’s a personal project to explore the possibilities of SQLite’s JSON and JSONB functions to their fullest. Sharing it here in case it interests any of you. Inviting everyone to try it out and share your feedback.
