Turnstile is a great product if you're already inside Cloudflare's ecosystem. If you're not, the trade-offs change.
Cloudflare Turnstile is genuinely impressive technology. The "managed challenge" approach — adapting the friction to risk in real time — is the right model, and Cloudflare's network position gives them excellent risk signal. For Cloudflare customers, Turnstile is essentially free and well-integrated. We're not going to pretend otherwise.
The trade-offs: Turnstile assumes you're a Cloudflare customer, or willing to become one. The verify endpoint sits inside Cloudflare's infrastructure. The widget loads from Cloudflare's CDN. Your CAPTCHA story becomes part of your overall Cloudflare dependency story. For some teams, that's fine — they already use Cloudflare for DNS, WAF, and CDN. For others, it's another dependency to manage.
TrustedCaptcha is a pure-play CAPTCHA service with no broader infrastructure ambitions. We don't run your DNS. We don't proxy your traffic. We just verify your forms.
| TrustedCaptcha | Cloudflare Turnstile | |
|---|---|---|
| Pricing | €0 free / €25/mo / €200/yr | Free; usage above 10M/month requires Cloudflare paid plan |
| Data residency | Germany — EU only | Cloudflare's global edge network |
| GDPR posture | Native; EU-only operator footprint | SCCs apply; some processing in US |
| Infrastructure dependency | None — independent service | Cloudflare account required |
| Visible challenges | 6 modes, customer-configurable default | Adaptive; Cloudflare picks |
| Audio mode for accessibility | Yes — default fallback | Limited; not feature-equivalent to visual |
| Drop-in compatibility | Supports cf-turnstile-response field | n/a |
| Open-source widget | Yes (MIT) | No |
| Self-hosted option | On roadmap (Pro Enterprise) | No — requires Cloudflare |
If you're already a Cloudflare customer, Turnstile is essentially free, well-integrated with the rest of the Cloudflare stack (Bot Management, WAF rules), and benefits from the highest-quality risk signal in the industry. The "no challenges most of the time" UX is excellent for legitimate users.
For high-volume B2C sites where Cloudflare's edge network already protects the rest of the property, adding Turnstile is a near-zero-cost decision with strong results.
Independence. We're not trying to sell you anything else — no DNS, no WAF, no CDN, no analytics, no R2 storage. The pricing is flat and predictable in EUR. The data stays in Germany. The audio fallback is a first-class feature, not an afterthought. You don't need a Cloudflare account.
For EU operators in regulated industries, the data residency story is materially better. Turnstile processes data through Cloudflare's global network; TrustedCaptcha keeps everything in one EU member state, with a published subprocessor list and a pre-signed DPA.
The widget reads cf-turnstile-response as well as its native trustedcaptcha-response, so existing form code keeps working. Server-side: change the verify URL. Full guide at /migrate/turnstile.
Use Turnstile if you're already a Cloudflare customer and the data flowing through Cloudflare's network is acceptable for your compliance posture. Use TrustedCaptcha if you want a CAPTCHA that's just a CAPTCHA — independent, EU-resident, accessibility-first, predictable.
