QEDServer: A standalone playground for JS and AJAX

QEDServer: A standalone playground for JS and AJAX launched on May 4, 2011 with 22 votes, #29 of 217 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 15 years on.

In plain words

QEDServer is a standalone playground designed to help developers test client-side JavaScript and AJAX libraries without building a backend. It eliminates the need to write server code, set up databases, or deploy applications, allowing developers to focus on experimenting with new client-side frameworks. The tool comes pre-configured with a development environment and dummy data, making it ideal for developers who want to quickly prototype and test rich client-side applications.

From the sources

You've just come across a great new client-side library that makes building richer client-side apps a breeze. It has support for client-side storage, but you're really interested in using this with an existing server-side web application, so you decide to try it out. Then you realize that to test everything, you need a backend. That means you need to write some server side code, set up a database, and you need to deploy the thing on a web server so that all the AJAX requests work right. And of course, you need to populate that database with dummy data. That's a lot of work just to try out a new framework! QEDServer solves those pesky problems for you so you can focus on sharpening your…from qedserver.napcs.com

  • qrframe – generate beautiful qr codes with javascript code2024 · github.com · ▲401

    I originally built a QR code generator as a resume project using Rust and I realized a web interface would make customization way easier. This still generates the "data" using that rust library via wasm, but the rendering is all editable javascript to make an SVG or paint on an HTML canvas. I was especially inspired by https://qrbtf.com which had some unique style options I had never seen before, which I ended up copying, and then I made some more.

  • I made a HTMX Playground 100% in the browser2024 · lassebomh.github.io · ▲482

    I recently dug up an old project in an attempt to improve on it. It's a code sandbox for playing around with HTMX in the browser, that runs a mock server within the sandbox iframe. The server "framework" is loosely based on Django, so if you're familiar with Django, you'll immediately understand what's going on. I recommend clicking through the examples. Github repo: https://github.com/lassebomh/htmx-playground Probably my favorite part is the lack of HTMX specific code. It's designed to mimic the client and server, but really nothing else. In principle, this means that…
