FastSvelte pairs a SvelteKit SPA with a FastAPI backend organized in an API, service and repository layering with dependency injection. It ships username/password and Google OAuth, role-based multi-tenant organizations with invitations, separate admin and user dashboards, Stripe subscriptions with webhook handling, and AI usage metering with monthly credit allowances and top-ups. Deployment is Docker-first, and email works through Resend, SendGrid or Azure. Plans are one-time: Solo ($159, 1 year of updates), Developer ($199, lifetime) and Team ($399, up to 5 developers).

Key Benefits

Python FastAPI backend with clean API → Service → Repository architecture
Multi-tenant organizations with roles and team invitations for B2B SaaS
Stripe subscriptions plus token-based AI credit metering and top-ups
Security hardening: Argon2 hashing, rate-limited auth, strict headers
Docker-first deploys to any VPS, cloud or on-prem environment
Working sample AI app with streaming responses and usage tracking

What Users Say
