Supabase
Cheapest plan not known to forbid this: Free: $0Free: $0Free: $0
Free to Pro is +$25 a month, and the Free plan pauses a project after a week without activity.
Database & backend price cliffs
Where database and backend free plans end and the paid price starts. 11 platforms so far.
Pick a use. Plans the vendor’s own terms forbid for it turn grey and dashed. “Unknown” means we have not found a restriction in the page we read, not that none exists. Heights use a square-root scale so $5 and $599 both show.
Neon
Cheapest plan not known to forbid this: Free: $0Free: $0Free: $0
Free has no fixed fee; Launch and Scale have no fixed fee either, so the “cliff” is metered cost: $0.106 per CU-hour on Launch, $0.222 on Scale, and $0.35 per GB-month.
Appwrite
Cheapest plan not known to forbid this: Free: $0Free: $0Free: $0
Free to Pro is +$25 a month per project. A new Start plan from $10 a month exists in selected regions; the old $599 Scale plan is retired.
Convex
Cheapest plan not known to forbid this: Free & Starter: $0Free & Starter: $0Free & Starter: $0
Free to Professional is +$25 a month per developer — the seat count, not the project, is what multiplies. Business starts at a $2,500 monthly minimum.
MongoDB Atlas
Cheapest plan not known to forbid this: Free (M0): $0Free (M0): $0Free (M0): $0
Free to Flex is about +$8 a month at the lowest band, capped at $30. Dedicated starts at $56.94 a month for M10. M2 ($9) and M5 ($25) still appear on the pricing page but are no longer supported, per the docs.
PlanetScale
Cheapest plan not known to forbid this: Postgres single-node: $5/moPostgres single-node: $5/moPostgres single-node: $5/mo
No free tier — the Hobby plan was retired in April 2024. Postgres starts at $5 a month for a single node, $15 for high availability; MySQL-compatible Vitess starts at $39. Storage, backups and egress are extra, and prices are quoted for AWS us-east-1 and vary by region.
Turso
Cheapest plan not known to forbid this: Free: $0Free: $0Free: $0
Free to Developer is +$4.99 a month on annual billing ($5.99 month-to-month). Turso announced in October 2026 that it is joining Supabase; pricing is unchanged so far.
Xata
Cheapest plan not known to forbid this: Trial: $0Trial: $0Trial: $0
No free plan on Xata Cloud — the old Free and $25 Pro plans are gone. Cloud is pay as you go from $9 a month for Micro, plus $0.28 per GB of storage. The open-source edition is free to self-host.
Crunchy Bridge

No free tier. Hobby clusters start at $9 a month; Standard starts at $70. Storage is $0.10 per GB a month on top, and prices are quoted for AWS East and vary by region.
