Lua / OpenResty · 10-15 minutes
Bot protection at the proxy level with Nginx
Add Centinel validation to Nginx using Lua scripts via OpenResty.
Real-time detection
Spot AI crawlers on your Nginx / OpenResty infrastructure the moment they access your site.
Under 2ms latency
Our validation API responds in under 2ms. Zero perceptible impact on your end users.
Crawler metadata
Every response includes crawler identification, category (AI training, inference, search), and access history.
How it works
Centinel + Nginx / OpenResty in three steps
01
Add browser script
A lightweight script sets a session cookie on protected pages.
02
Configure Nginx / OpenResty
Your Nginx / OpenResty instance calls our validation API for protected endpoints.
03
Enforce decisions
Allow, block, or challenge based on the real-time API response.
