  • •Idempotent logging tracks every credit change for audit trails and debugging.
Weaknesses
  • •$129 price point is steep when Lemonsqueezy and Stripe Billing native features exist.
  • •Locked to Next.js and Supabase stack limits adoption for other backend preferences.

Shipfast.so – Next.js boilerplate with auth, payments, email, database

Shipfast is essentially a curated, clone‑and‑go Next.js repo that tackles the annoying plumbing — real Auth0 flows, Stripe webhooks, Resend transactional emails, MDX blog, and even an AGENTS.md for LLM integration. That focus on the pain points devs actually waste time on (payments + email + auth) is the selling point; it's not novel technology, just useful, well‑assembled wiring with sensible defaults and a dark UI.
