WebServerMonitor vs JS Server

If a server becomes unreachable or returns an unexpected status code (any other than HTTP/2xx), WebSMoni immediately notifies you via push notification. The monitoring happens directly on your iPhone or iPad – no third-party services or external servers are involved. WebServerMonitor is designed to be efficient and easy to set up, just concentrating on the important things: informing you about the status of your web servers.

Server turns your iPhone or iPad into a developer-friendly HTTP host. Point a listener at a file and it gets served. Write JavaScript and it runs. WHAT YOU CAN DO Serve static files Pick a file from the Files app, or edit one inline. Custom Content-Type per listener. A default HTML page is provided for quick smoke tests. Write JavaScript routes Every JavaScript listener gets an Express-like surface running inside JavaScriptCore. Register routes with server.get, server.post, server.all, and respond with res.html, res.json, res.text, res.send. Set status and headers fluently. No Node dependency. Your code evaluates on device. Read and write files from JS A sandboxed fs module is bridged through Swift: readFile, writeFile, exists, mkdir, readdir, unlink, stat. Every listener gets its own private directory. Any path that tries to escape the sandbox is rejected. Call external APIs Outbound fetch is bridged too. Pass a URL, optionally a method, headers, or a body, and get back status, ok, headers, text, and json. Perfect for proxies, webhooks, or quick integrations. Run multiple listeners at once Each listener runs on its own port, started and stopped independently. Bonjour advertises them on your local network so peers can find them by name. Live Activities A listener running in the background shows up in the Dynamic Island and on the Lock Screen with the port and request count. Inspect every request The Console panel logs every HTTP request, every console.log, and every runtime error. Tap an HTTP row to expand the full request (method, URL, headers, body) and response (status, headers, body, timing). Syntax highlighting In-app editor with an IDE-style dark theme for JavaScript, Python, and HTML. WHO IT IS FOR Developers prototyping APIs on the go. QA engineers testing mobile clients against a controllable backend. Anyone who needs to serve a JSON blob, a mock endpoint, or a small HTML page from their iPad without setting up a real server. PRIVACY No accounts, no telemetry, no analytics. Nothing leaves the device except the HTTP responses you explicitly send. All code, data, and logs live in your app sandbox.
