Deploy and Host Express + WebDecoy Bot Detection on Railway

An Express app with WebDecoy bot detection already wired in. WebDecoy records the scrapers, AI crawlers, and automated tools hitting your routes, flags crawlers that fake their identity, and plants a hidden honeytoken link that only bots follow. Deploy it as a starting point, or copy the few lines in server.js into your own app.

About Hosting Express + WebDecoy Bot Detection

The template is a single Node.js service built from a public GitHub repo, with a /health route for Railway's healthcheck. It needs one variable: WEBDECOY_API_KEY, which you create for free at app.webdecoy.com under Settings, API Keys. The middleware starts in monitor mode, so detections are recorded and every request is still served. It reads the real visitor IP from Railway's proxy headers: Railway's X-Forwarded-For holds the client address followed by its own edge address, so the app trusts two hops rather than one. Without a key the app still runs, with local rules only.

Common Use Cases

See which AI crawlers and scrapers are reading your API or site, and which ones are forging a known crawler's user agent
Catch scrapers with a hidden honeytoken link that people never see or follow
Start in monitor mode, then switch to enforce and return a 403 to automated traffic once you trust what it flags

Dependencies for Express + WebDecoy Bot Detection Hosting

A free WebDecoy account and API key (app.webdecoy.com)
Node.js 20 or later (Railway's builder provides it)

Implementation Details

app.set('trust proxy', 2); // Railway: client, then Railway's edge

app.use(webdecoy({
  apiKey: process.env.WEBDECOY_API_KEY,
  skipPaths: ['/health'],
}));

Prove it reports: curl -A "WebDecoy-Test/1.0" https://YOUR-APP.up.railway.app/ fires a detection labeled Test in your WebDecoy dashboard, excluded from stats and billing.
