Resources and replicas
Change a Quick App's CPU, memory, and disk, and set its replica count.
View current resources
An app's resources are shown on the app page and in the Resources column of the list:
- CPU
- RAM
- Disk
Change resources
- Choose Plan from the app menu.
- Change CPU, Memory, and Disk.
- Check the new price in Price Estimation.
- Click Apply Changes.
Ranges:
- CPU: 1–32 cores
- Memory: 1–32 GB
- Disk: up to 200 GB
Rules:
- Memory cannot be less than the CPU count and is at most 4× the CPU count.
- Disk can only grow; shrinking is not supported.
- For Redis, disk must be at least twice the memory size.
- Applying new resources restarts the app and may take a few minutes.
Billing is hourly, and the Plan dialog shows a monthly estimate.
Replica count
The Scale option is only shown for multi-node apps, such as three-node PostgreSQL and MySQL, RabbitMQ, and Elasticsearch.
- The count must be odd: 1, 3, 5, and so on.
- Choosing 0 stops the app.
- Each replica uses the plan's resources.
- Applying changes may take a few minutes.
Most Quick Apps, such as WordPress, Grafana, and n8n, run a single replica and do not show the Scale option.
Billing
- App resources are billed hourly and deducted from your balance.
- While the app is stopped, its resources are not billed.
- Companion databases and volumes are billed separately.
- Change resources during low traffic; the app restarts.
