The receipts — real demand
“Replies: 0 I just set up my contact form with Turnstile and all seems to be working. However, when I check the cloudfare dashboard, it says Siteverify isn’t being called for <site name> Without a server-side siteverify call, widget tokens aren’t validated. The forms these widgets protect remain open to bots. Is this a known issue, why is it happening?”

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Contact Form 7 users (millions of WordPress sites) who have added Cloudflare Turnstile but need server-side verification enforcement. No search volume and zero forum replies suggest this is a security compliance edge case, not a high-volume demand.
Competition & the opening
Extremely crowded (8/10). At least 6 named plugins and Cloudflare's official WordPress plugin already exist. The gap is narrow: most plugins do client-side verification only; the specific pain is server-side siteverify validation to prevent spoofing.
What's hard to build
Requires correct Turnstile API credential handling (secret key management in WordPress), server-side POST to Cloudflare siteverify endpoint, and robust error handling for Cloudflare API latency or downtime. Timing and state management in CF7's form processing pipeline is fragile.
Why now
Cloudflare Turnstile adoption is rising but most free CF7 plugins skip server-side verification, leaving sites vulnerable to bot replay attacks.
