Reviewer scorecard
“Atlas is excellent — search, vector, triggers, and serverless functions. The aggregation pipeline is powerful once you learn it.”
“Built-in vectorizer modules mean less glue code. GraphQL API is intuitive. Self-hosting option is a huge plus.”
“Document databases create more problems than they solve for most apps. Start with Postgres, add MongoDB only if you truly need it.”
“Open source and self-hostable gives you an exit strategy. The module system is genuinely innovative.”
“Atlas Vector Search positions MongoDB well for AI applications. Their platform play is smart.”
“Multi-modal vectors and generative search point to where databases are heading. Weaviate is building for that future.”
