Reviewer scorecard
“Atlas is excellent — search, vector, triggers, and serverless functions. The aggregation pipeline is powerful once you learn it.”
“Self-hostable, open source, and genuinely all-in-one. Replaces Amplitude + LaunchDarkly + Hotjar at a fraction of the cost.”
“Document databases create more problems than they solve for most apps. Start with Postgres, add MongoDB only if you truly need it.”
“The free tier is absurdly generous. Open source means you can audit exactly what data goes where.”
“Atlas Vector Search positions MongoDB well for AI applications. Their platform play is smart.”
“PostHog is the open-source Amplitude. The all-in-one approach reduces tool sprawl and keeps data unified.”
