Asia reachability
CaptchaLa endpoints are reachable from mainland China. Verification completes without a separate SDK, account or billing arrangement.
Background
reCAPTCHA loads from Google domains, which are not reachable from mainland China. Forms that depend on it cannot be completed there, and the failure produces no error message — the form simply never becomes submittable.
Service coverage
CaptchaLa serves from APAC edge nodes in Singapore, Hong Kong and Vietnam, in addition to its US and EU points of presence. Requests from mainland China are handled by the nearest APAC node.
The widget loads and the form remains submittable.
Cross-border requests have higher latency than in-region traffic, and reachability is subject to network conditions.
Comparison
| Google reCAPTCHA | Not reachable | Loads from Google domains, which are blocked in mainland China. |
|---|---|---|
| Cloudflare Turnstile | Inconsistent | Reachability depends on Cloudflare's presence in mainland China, with no alternative path. |
| CaptchaLa | Reachable | Served from the nearest APAC edge node. Higher latency than in-region users. |
| Domestic providers | Reachable | In-country nodes and lower latency, typically requiring a domestic contracting entity and Chinese-language documentation. |
