Stripe-Free Next.js Starter: Skip Stripe KYC. Next.js 14 + Supabase + Gumroad boilerplate

Hey Product Hunt! I'm Gian, a CS student and solo builder. The standard "just use Stripe" advice for SaaS billing is a trap for solo devs. Setting it up means drowning in KYC hurdles and global VAT compliance before you even get your first customer. I just wanted to write code, not play accountant, so I shifted my stack to use a Merchant of Record (Gumroad). But I quickly hit a wall. Almost every Next.js + Gumroad tutorial out there is dangerously insecure. I spent days engineering a strict, 100% fail-closed webhook validation system that ties directly into Supabase RLS. If a webhook drops, a payment fails, or a subscription cancels, access is instantly and gracefully revoked at the database layer. No ghost access, no manual database cleanup. I packaged this exact setup into a boilerplate so you can bypass the tax headaches and launch securely on day one. PH Launch Bonus: Use EARLYBIRD at checkout for 50% off (limited to the first 20 uses). I'd love to hear your thoughts. Are you still dealing with Stripe tax overhead, or have you made the jump to MoRs like Gumroad to save time? Let me know below.
