At the perimeter

Edge connectors

Decide at the edge before traffic reaches your origin — Cloudflare Workers and nginx/OpenResty, fail-open by design.

Cloudflare Worker

@prynt/edge-cloudflare

# wrangler.toml → deploy at the edge
npm install @prynt/edge-cloudflare

Decides allow / challenge / block sub-10ms, serves the agent first-party under /__prynt/*, fail-open.

nginx / OpenResty

edge-nginx

# auth_request + OpenResty Lua
# see packages/edge-nginx/README

Gate any origin with an auth_request subrequest — no app code changes required.
