Simple pricing, straight answers.

What is CPU share?

CPU share is the compute your account is guaranteed when the server is busy, measured in CPU Slices. Free includes 1x CPU Slice, Standard 2x CPU Slices, Pro 4x CPU Slices and Scale 16x CPU Slices. When the server is quiet, every plan runs at full speed.

What do SendJet, AuthJet and MapJet add?

Every plan includes SendJet, AuthJet and MapJet at the matching tier, with that tier's allowances. Bought separately, the three Pro tiers cost $98 a month. Pro is $9. If you need more of one service, add that service's plan. Your account always uses the higher limit.

Can I add space?

Extra space is available on Scale, at $1/month per extra 10 GB. On Free, Standard and Pro, upgrade to a larger plan for more space.

Are reads, writes and functions really unlimited?

Yes, on every plan. Substrio never caps or bills the reads, writes and function calls your apps make. Your plan sets your space, apps and CPU share. Each service counts only what it prices.

What is an app?

An app has its own data, functions, site and domains. Free includes one app, Standard three, and Pro and Scale unlimited apps, all sharing the plan's space.

Start free.Upgrade when you need more.

Free needs no credit card and never expires. Your app goes live on Free; move to Standard at $5/month when it grows.
