MongoDB Atlas vs Supabase Pricing (2026)

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?

Different approach here. MongoDB Atlas uses usage-based pricing, while Supabase goes with hybrid. That changes the math depending on your team size and usage.

Which one is a better deal?

Depends on what you need. MongoDB Atlas: MongoDB sits mid-to-premium in the database-as-a-service space — pricier than raw self-hosted Postgres or DynamoDB's pay-per-request model, but justified by the managed ops layer and document-model flexibility. They're clearly hunting teams who've outgrown free-tier NoSQL options and need something that won't fall over at scale. Supabase: Supabase undercuts Firebase and traditional Postgres hosting on entry price, using the free and $25 tiers to hook indie devs and small startups away from rolling their own backend. But that Pro-to-Team gap ($25 to $599) is huge compared to competitors with more gradual mid-tier steps, so they're clearly not trying to compete for mid-market on price — they want you locked in cheap early, then captive when compliance needs kick in.
