LaunchKit - Premium FastAPI SaaS Backend: The FastAPI backend with the parts everyone skips

Hey everyone 👋 Maker here. Quick story on why this exists — I was starting a new project that needed teams with permission levels, 2FA, and usage-based plans on top of the usual login/Stripe stuff. Looked around for a FastAPI starter that had all this and... mostly found the same "JWT + Stripe checkout" template everywhere. The Django world has SaaS Pegasus for this ($250-1000), but nothing equivalent existed for FastAPI. So I built it properly instead of bolting it on later: • JWT auth with rotating refresh tokens (stolen tokens die on reuse) • TOTP 2FA + recovery codes, Google/GitHub OAuth • Multi-tenant orgs with owner/admin/member roles + email invites • Per-plan usage quotas with 402 enforcement • Customer-facing webhooks, HMAC-signed exactly like Stripe's scheme • Stripe subscriptions with idempotent webhook handling • Audit logs, rate limiting, Docker, CI — 22 passing tests The demo site lets you click through every endpoint and see real responses, not screenshots — figured that's more honest than a feature list. $399 for the first 25 (goes to $499 after). Would love feedback, especially if you've hit the same gap or there's something you'd want added.
