Feedback from founders and developers using WaitKit to validate demand before launch.
Added WaitKit before my landing page was done. We started collecting real emails the same day.
API-first done right. WaitKit gave us secure endpoints and a simple SDK without backend busywork.
Real-time waitlist counts made our prelaunch page feel alive. It pushed our signups up fast.
We stayed fully headless and kept our own UI while WaitKit handled storage, auth, and export.
Exactly what we needed for idea validation. We launched in hours, not weeks.
WaitKit removed all the waitlist infrastructure work so we could focus on product and onboarding.
Start with a generous free plan. Move to Pro when your waitlist takes off.
