Compute

A session is charged by the vCPU-hour. Each vCPU comes with 2G of memory and 16G of disk. A session that asks for more memory or disk than its vCPUs come with is charged for the vCPUs that would bring it: a session of 2 vCPUs and 8G of memory is charged as 4 vCPUs.

Class	Region	Description	₡ a vCPU-hour
`standard-ip`	Europe	Standard performance, the default	₡0.15
`standard-ie`	Europe	Reduced performance	₡0.12

A class costs the same on every plan. machine sessions classes lists the classes and their current prices.

Regions

Each class runs in one region, and the runs of its sessions are stored there. One account and one balance of credits work in every region.

Questions

What is a credit?

Credits pay for the vCPU-hours your sessions use. One vCPU for one hour costs ₡0.15 on standard-ip and ₡0.12 on standard-ie. Machine writes an amount of credits with the sign ₡, so ₡0.15 is 0.15 credits. A credit has no cash value.

How is a session charged?

A running session is charged an hour ahead. When it stops, the unused part of its last hour is given back. machine account activity lists every charge.

What happens to credits I do not use?

Plan credits renew at the start of each period, and the ones left over expire. Usage credits do not expire.

How do I buy usage credits?

Usage credits are bought on top of any plan at €1 a credit, in packs of ₡5, ₡10, ₡25 and ₡50. Buy them on the account page or with machine account buy-usage.

Which plan is right for me?

Free shows what Machine does on your own programs. Starter fits one developer's everyday testing. Plus fits larger sessions and more of them. Pro fits long recordings and heavy exploration. For machines reserved for your team, contact sales@testflows.com.

What happens when I cancel?

The plan stays until it renews, then the account moves to Free. Your usage credits stay.

The Usage Credit Terms say how credits are granted and used. Account and billing covers the commands that buy and manage them.
