📊 Capacity Planner
Extrapolate DynamoDB WCU/RCU requirements and AWS cost at 10×, 50×, and 100× current scale. Seeded from live /beak/system/status.
Current Platform Scale
Live counts from GET /beak/system/status — used as the baseline for all scale projections.
Scale Scenario
Select a growth multiplier to project costs and DynamoDB capacity. All figures are monthly estimates.
Near-term growth
~10x current ducklings/agents — first milestone or early traction
Rapid scaling
~50x current — sustained growth after product-market fit
At scale
~100x current — long-term platform scale, SES/SNS upgrade required

Estimates use AWS on-demand pricing (us-east-1, 2026). Lambda includes 1M free tier requests/month. DynamoDB uses pay-per-request. SES first 62,000 emails/month free from EC2. CloudFront first 1TB/month free. Actual costs will vary.
DynamoDB Capacity Requirements
WCU/RCU projections per table at selected scale. All tables use pay-per-request (on-demand) — no reserved capacity needed. Figures show peak estimated throughput.

WCU = 1KB write. RCU = 4KB strongly-consistent read. Pay-per-request charges $1.25/million WCU and $0.25/million RCU (us-east-1). First 25 WCU/RCU per table provisioned free tier not applicable for on-demand.
