App sizes & scaling
Pick an application size that matches your workload, then upgrade when you need more CPU or memory.
Choose a size when creating an app
Sizes are limited by what your plan allows.
- Start New application.
- Under Application size, pick a preset that fits your expected CPU and memory needs.
- Create the app, then build and deploy as usual.
If a size you want is not listed, your current plan may not include it — check Billing or contact support.
Change size later
Upgrade when traffic or workload grows.
- Open the application settings (or the size section on the app page).
- Review eligible size presets for that app.
- Request or apply a size change according to the UI — some plans apply immediately; others may require acknowledgment or approval.
- After the size change is applied, deploy again if the UI indicates the live app should be refreshed.
Practical tips
- Start smaller for early development; scale up when builds or runtime need more headroom.
- Watch build minutes, egress, and deployment limits on Billing — size is one part of plan capacity.
- Pair sizing with solid environment configuration and custom domains when you go production.
