Carrd Waitlist Integration
Why use LaunchList with Carrd?
Carrd is the fastest way for indie hackers to ship a one-page site. It has a built-in form, but no referral system, no leaderboard, and no spam protection. LaunchList adds all three via Carrd's native Embed element — no external tools, no monthly subscription.
What you get:
- Viral referral program — every signup gets a unique referral link that moves them up the waitlist
- Fraud detection — disposable email blocking, MX validation, and behavioral scoring on every submission
- Two integration modes — use the pre-built embed widget or wire up Carrd's own form via Custom Form mode
- CSV export — download your full list any time
- Free plan — up to 100 submissions, no credit card required
Setup takes under 3 minutes. Requires a Carrd Pro plan for the Embed element and custom scripts.
