How Bubble Actually Scales -- Workload Units
Bubble's capacity model is based on Workload Units (WU), a metric that reflects how much server work your app's searches and workflows actually consume -- the concrete scaling lever is optimizing WU consumption (efficient searches, indexed constraints, lean workflows), not a vague "grows with you" claim.
Practical Details
Dedicated capacity plans exist for apps that need guaranteed, consistent performance regardless of shared-resource contention, which matters specifically for production apps with real paying users where occasional slowdowns are unacceptable.
Actionable Considerations
- Monitor Workload Unit consumption in your Bubble dashboard as real usage grows, not just user count
- Optimize database searches and reduce unnecessary workflow steps specifically to lower WU consumption
- Move to a dedicated capacity plan if your app needs consistent performance under real production load
