Slot Scale Scale deployments from development to production with paid tiers, replicas, and multi-region. Instance Tiers Tier Specs Storage Cost Basic Limited CPU & memory 1GB $10/month Pro 2 vCPU, 4GB RAM auto $50/month Epic 4 vCPU, 8GB RAM auto $100/month Legendary 8 vCPU, 16GB RAM auto $200/month First 3 Basic tier deployments are free. Storage on premium tiers: $0.20/GB/month (auto-scaling). Basic tier behavior Scaled down automatically after a few hours of inactivity Revived on first request Deleted if unused for 30+ days Premium tiers (Pro+) Never scaled down or deleted while the team has credits Auto storage scaling (never runs out of disk space) Replicas Torii supports multiple replicas on premium tiers: slot d create --tier epic my-project torii --replicas 3 Billed per replica (3 replicas = 3× tier cost). Katana does not support replicas. Regions Region us-east europe-west Deploy in multiple regions with --regions :

Torii: multi-region with replicas

slot d create --tier pro my-project torii --regions us-east,europe-west

Katana: single region only

slot d create --tier pro my-project katana --regions europe-west Billing: tier cost × regions × replicas. Creating Paid Tier Deployments Ensure the team has credits (see slot-teams skill), then: slot d create --tier epic --team my-team my-instance torii Upgrading an Existing Deployment Tiers can only be upgraded, not downgraded: slot d update --tier epic my-instance torii The team that owns the deployment must have sufficient credits.
