Database platforms compared: prices and price hikes
Where your app's data lives: managed Postgres, MySQL, NoSQL and Redis databases, plus backend platforms like Supabase and Firebase that add auth, APIs and storage, compared on what the same app database costs at three sizes.
Prices at a 10 GB production app
- Firebase: $6.36/mo
- Amazon RDS: $13.98/mo · last hike Mar 2025
- Neon: $23.75/mo
- Supabase: $25.25/mo
- MongoDB Atlas: $178.40/mo
Every price is the monthly cost, at list prices on monthly billing, of running the same app database in a US region: a 10 GB production app (the headline), a 250 MB side project and a 100 GB growing app, each with a fixed number of reads, writes and developers, on the cheapest self-serve plan that fully covers it. Free plans count when they cover the whole job and allow production use; trials and sign-up credits do not.
