The team’s goal is to become “the de-facto open-source alternative to MongoDB.” Here’s why:

MongoDB is a life-changing technology for many developers, empowering them to build applications faster than using relational databases. Its easy-to-use and well-documented drivers make MongoDB one of the easiest to use database solutions available. However, MongoDB abandoned its open-source roots, changing the license to SSPL - making it unusable for many open source and commercial projects.

Most MongoDB users are not in need of many of the advanced features offered by MongoDB; however, they are in need of an open-source database solution. Recognizing this, MangoDB is here to fill the gap by providing an alternative.

This is currently a proof of concept. The concept: a proxy that converts Mongo’s wire protocol to SQL and stores everything in PostgreSQL. Fascinating idea! Will it work?
