MongoDB Atlas vs Supabase FAQ
- Which one is cheaper?
- MongoDB Atlas starts lower at $0/mo, compared to $25/mo for Supabase.
- Can I use either one for free?
- Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.
- How do they charge?
- Both use a usage-based model, so the comparison is straightforward — it comes down to features and limits at each price point.
- Which one is a better deal?
- Depends on what you need. MongoDB Atlas: Atlas sits in the premium tier of managed databases, competing directly with AWS DocumentDB and Azure Cosmos DB, but leans on MongoDB's native compatibility as a differentiator over cloud-vendor lock-in alternatives. They're not the cheapest option — they're pitching developer experience and ecosystem depth to teams that want to avoid the friction of self-managing MongoDB. Supabase: Supabase is the scrappy, open-source alternative to Firebase — cheaper entry point, more transparent pricing, and no Google lock-in anxiety. They're targeting developers who want AWS-level infrastructure control without the AWS-level complexity or cost, competing directly with Firebase and PlanetScale in the mid-market.
