Your app works in preview but breaks on deploy. It's not your code — it's 5 settings nobody told you about.

It covers 20 errors (25 with Pro) across apps built in Lovable, Bolt, Replit, Cursor or Base44 that use Supabase + Stripe — the stack these tools default to. The fixes live in the Supabase, Stripe and hosting dashboards, so they apply whichever builder made your frontend. It targets the errors that actually break most vibe-coded deploys — env vars, RLS, auth redirects, SSL, webhooks and the rest. It won't cover every conceivable error, but if you're stuck on deploy, auth or payments on this stack, the odds it's in here are high.

That's exactly who it's for. Every fix is a plain-English symptom, an exact click-path spelled out step by step, and a prompt you copy-paste — no code to write yourself. If you can duplicate a Notion page and paste text into Lovable, you can do this.

Because half these problems don't live in your code — they live in the Stripe dashboard, Supabase policies or DNS, where your builder can't see. The Failure Index™ tells you exactly what to change there (the part the AI can't touch), and gives you a precise paste-back prompt for the code-side half — instead of the vague "fix it" loop that burns credits.

The failure set is stable — env vars, RLS, OAuth redirects, SSL, webhook URLs have been the top causes all year. When a dashboard UI moves, I update the kit — and every buyer gets the updates free. You're buying the maintained map, not a snapshot.

It's an index, not a course. You Cmd+F your exact error, land on one card, and follow three short steps — the symptom, the dashboard fix, and a prompt you paste into your builder. Most fixes take under 30 minutes. You're not studying anything; you're looking up the one answer you need and shipping tonight.

Two reasons. Run the Pre-Ship Checklist before your next deploy and you skip the 11pm crisis entirely — cheaper as insurance than as a rescue. And €39 is the founding price; it steps to €49 once the first reviews are in. Grab it now, use it the day something breaks — it's yours forever.

A Notion page you duplicate to your workspace in one click, plus a PDF mirror so you're covered even without a Notion account, plus the installable Claude skill — all instant, in your inbox in about 60 seconds. Nothing to install, works on any device, yours forever with free updates. One-time payment, not a subscription.

The kit includes a ready-made Claude skill (a small folder with a SKILL.md + the Failure Index). Drop it into Claude Code's skills folder — or add it in Claude Desktop — and it activates automatically when you describe a deploy, auth or payment error. Paste your red error and Claude finds the matching card and hands you the exact dashboard fix and the paste-back prompt, right in your chat. Install instructions are in the kit.

One stuck deploy costs you a lost weekend and a stack of AI-builder credits burned on "try to fix" loops that never touch the real problem. €39 — under €2 per error — is cheaper than a single one of those nights, and unlike credits it's a one-time payment you keep forever. It's not "a PDF"; it's an indexed map plus the paste-back prompts and the Claude skill that actually apply the fix. If your time is worth anything, this pays for itself the first time you're unstuck in 30 minutes instead of a weekend.

Check before you buy — paste your error into the finder at the top of this page and it tells you on the spot whether it's in the index. The kit covers the 20 (25 with Pro) errors that break most vibe-coded deploys on the Lovable/Bolt/Replit/Cursor/Base44 + Supabase + Stripe stack, so if you're stuck on deploy, auth or payments there, the odds are high — but it won't cover every exotic edge case. Because it's an instant-delivery digital product, all sales are final (see our Sales Policy), so use the free finder and the free checklist first to confirm it's a fit.

No — and that's the point. Unlike a Fiverr "fix my deploy" gig, you never give anyone your accounts. The kit tells you exactly what to click inside your own Supabase, Stripe and hosting dashboards, and gives you a prompt to paste into your own builder. Your credentials never leave your hands, and you learn where the setting lives so you can fix it yourself next time.
