I agree - Postgres has been on the rise for the past years, but I think the reason for MongoDB going down in popularity is not reflective of its own progress - MongoDB has only been technically getting better and they’ve recently bought Voyage AI which is now bringing built-in embeddings with MongoDB Atlas vector search.

The previous startup I’ve co-founded has been running on MongoDB since 2014 and everything was great for over 10 years of using it as our main db, hosting over million users and large enterprise customers.

A lot of this is obviously subjective, but we’ve always found MongoDB’s flexibility work great for a startup’s constant db changes. And we also believe that the existence of “Supabase for MongoDB” will be a good reason for more people to use it.
