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

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.
