More in Core
Studios
Multi-tenant architecture. Each studio gets its own subdomain, branding, and configuration. Everything is isolated — one studio never sees another's data.
Authentication
Magic link login and Google OAuth for parents. Role-based access for admins and instructors. No passwords to forget, no shared logins.
Payments Core
Stripe Connect integration. Each studio connects their own Stripe account and collects payments directly — Unstack charges a small platform fee per transaction.
Email Core
Transactional email delivery via Resend. Booking confirmations, invitations, reminders — all styled with your studio's branding.
