“Replies: 0 I am using the current version (2.0.0.2) of WPForms Lite with Cloudflare Turnstile enabled.

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
WordPress form builders using Cloudflare Turnstile. No search volume, but the pain is acute: WPForms' native Turnstile integration lacks server-side token validation, leaving forms vulnerable to replay attacks.
Competition & the opening
Very crowded (9/10). Simple Cloudflare Turnstile, Formidable Forms, OOPSpam, CleanTalk, and CWeb Form Protection all offer server-side Turnstile validation for WordPress. WPForms itself has Turnstile support but only client-side. The gap: WPForms Lite users are stuck with client-side validation unless they switch plugins.
What's hard to build
WPForms is a closed ecosystem; building a server-side validation bridge requires hooking into WPForms' form submission lifecycle and Turnstile's API without official hooks. Maintaining compatibility across WPForms versions and handling token expiry/validation errors reliably is fragile.
Why now
WPForms' Turnstile integration is client-side only while free competitors now offer server-side validation; a native WPForms addon closes a security gap.
