ServerDevTools Documentation

Inspect, trace, and debug your Node.js backend from one developer-focused dashboard.

ServerDevTools is an embeddable inspector for Node.js applications. It records the request lifecycle in a local SQLite database and serves an authenticated dashboard from your existing HTTP server.

ServerDevTools works on any Node.js server, and the /_devtools dashboard is protected by the configured username and password. Because it can display sensitive request data, use strong credentials, HTTPS, and restrict access to trusted environments where possible.

Install


npm install server-devtools

Install the SDK, preload instrumentation, mount the middleware, and inspect your first request.
