This app’s name is an homage to the world’s first web server. Back in 1989, Tim Berners-Lee started the web on his NeXT computer. On that computer was an app named WorldWideWeb. This app was unique because it allowed his machine to edit and serve HTML documents. The app also used coding frameworks that were adopted by Apple after purchasing NeXT: they are being used right now to display what you’re reading. Like that original app, this WorldWideWeb is a handy web development tool. It’s designed for people who need to test things on their iPad or iPhone before moving the files onto a real web server like Apache or nginx. It also allows you to work in those increasingly rare moments where you don’t have a connection to the Internet. App developers can use this server to simulate and test APIs that their product uses. FEATURES WorldWideWeb does things differently than today’s production web servers: • Automatic refresh — Watches your site and reloads browser when there are changes • No caching — Every request gets a new response, no cache busters needed • Easy to configure — Pick a folder and go • Directory listings — A handy list of files whenever you hit a URL that doesn’t exist • Bonjour support – Automatic DNS for easy access using devices on your local network • REST support — Set default responses as JSON or XML for easy mocking of APIs • No external dependencies — Completely standalone and doesn’t need other tools like Python or Ruby • Built-in security — Runs completely in a sandbox, no access to data unless you allow it • Powerful and lightweight – A small memory footprint with minimal CPU overhead • No rocket science — Perfect for clients and other folks who are less technically inclined

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.

Verdict

The call

The clearest difference is price: WorldWideWeb at Free against JS Server's $4.99. WorldWideWeb also leads on chart position (#202 vs unranked) and iOS requirement (15.0 vs 17.0). JS Server's advantage is in-app purchases (none vs 1) and update cadence (daily vs every 4 months). On ads and device support there is nothing between them.
