Product FAQ
Factual answers — if your edge case isn't covered, email us after purchase.
No for receiving the ZIP (Gumroad delivers it). Yes only if you want to sell digital products through your own deployed site using the included Lemon Squeezy checkout flow. The 7 other catalog items are demo examples for that pattern.
Yes. Idempotent Lemon Squeezy webhooks with Postgres locking, RLS on tables, production CSP, E2E tests on auth and checkout, and GitHub Actions CI. This stack runs in production today.
Technically yes, but the kit is built around Supabase Auth + Postgres. Migrating to Clerk + Neon would take a few hours of refactor.
Yes. Build and sell unlimited SaaS products with this starter. You may not resell the kit itself as-is.
90-day weekday email support for setup blockers, plus lifetime v1.x updates via Gumroad Library.
After paying on Gumroad, you receive the ZIP through their delivery system (email / library). 14-day guarantee as defined on Gumroad for this product.
