Introducing the Cloudflare Turnstile Integration
Secure your forms with Cloudflare Turnstile—now available out-of-the-box in Formspree.
Formspree now supports Cloudflare Turnstile out-of-the-box, giving you a modern, privacy-focused alternative to secure your forms without frustrating your users!
The CAPTCHA Conundrum
We know the pain points well: traditional CAPTCHAs present the user with a challenge to solve, which adds a cognitive load for them while adding friction to the overall experience.
Such challenges can introduce significant accessibility barriers as well.
The Turnstile Advantage
Cloudflare Turnstile is a cutting-edge bot detection service without puzzles and visual challenges for frictionless, non-interactive verification.
Instead of asking users to click on buses or street signs, Turnstile analyzes browser and client behavior by running lightweight, non-intrusive JavaScript challenges in the background. It verifies humanity and malicious traffic with high accuracy, all while maintaining a smooth user flow.
This approach offers two massive advantages:
- Superior UX & Accessibility: The vast majority of real visitors will never see a challenge, resulting in faster form completion and better conversions.
- Privacy-Focused: Unlike older systems that track users for other purposes, Turnstile is built from the ground up to respect visitor privacy.
Making Turnstile Even Better
Turnstile is fantastic, but it still requires one critical step that complicates your build: server-side validation of the token it generates.
That’s where Formspree steps in.
With our native integration, we handle the entire server-side exchange immediately upon form submission. You simply configure your keys in the dashboard, and Formspree automatically verifies the cf-turnstile-response token using your Secret Key.
Turnstile or CAPTCHA: How Do You Decide?
Turnstile is the modern default for most teams: it keeps forms fast, accessible, and private, and it removes the challenge screens that hurt conversions. If you want the least friction for real users and the strongest signal for bot traffic, Turnstile is almost always the better choice.
That said, some setups still rely on traditional CAPTCHAs; especially older workflows, strict compliance environments, or integrations that already bake in Google’s challenge-response flow. If you’re maintaining a legacy stack or need continuity with an existing security policy, CAPTCHA may still fit.
With Formspree, you don’t have to commit permanently. You can start with Turnstile for a smoother user experience, switch to CAPTCHA if your requirements demand it, or even run A/B tests to compare real-world performance. Either option works. The goal is to choose the one that keeps your forms both secure and frustration-free.
