What digital tools are available on moritzglantz.de?

Updated

moritzglantz.de hosts five small browser-based tools built by Moritz Glantz, a UX engineer and accessibility specialist based in Karlsruhe, Germany. They are listed on the site's "Project Highlights" section: an Accessibility Cheatsheet, a WCAG Color Contrast Tester, a Morse Code Generator, a Tracking-free QR-Code Generator, and a Relax Sound Board. All of them are self-built projects and are used directly in the browser — no account or installation is mentioned on the site.

The five tools at a glance

Tool What it is for Typical use
Accessibility Cheatsheet A quick reference for accessibility rules and patterns Checking requirements while building or reviewing a page
WCAG Color Contrast Tester Checking whether foreground/background color pairs meet WCAG contrast requirements Validating text and UI colors before shipping a design
Morse Code Generator Converting text into Morse code Learning, hobby projects, or encoding short messages
Tracking-free QR-Code Generator Creating QR codes without tracking Sharing links or data without adding analytics to the code
Relax Sound Board Playing calming sounds Background audio for focus or winding down

Accessibility-focused tools

Two of the five tools sit squarely in Glantz's stated specialty — web accessibility and UX engineering.

Accessibility Cheatsheet

This is a reference resource rather than an interactive checker. It is aimed at the moment when you need to confirm how a pattern should behave or which requirement applies, without digging through the full WCAG documentation. It is most useful as a working reference during design and development, not as a replacement for formal conformance testing.

WCAG Color Contrast Tester

This tool addresses one of the most common accessibility failures: text that is too low-contrast against its background. You use it to test a specific color pair and see whether it passes WCAG contrast thresholds. The practical workflow is:

  1. Pick the text color and background color you plan to use.
  2. Enter them into the tester.
  3. Read the result and adjust the colors until the pair passes.

The common snag is testing only the default state — hover, focus, disabled, and placeholder text colors often fail even when the main body text passes.

Utility and generator tools

Morse Code Generator

Converts typed text into Morse code. Useful if you want to encode a short message, teach yourself the code, or produce Morse output for a project without installing anything.

Tracking-free QR-Code Generator

Generates QR codes with the explicit promise of no tracking. This matters if you are publishing a QR code and do not want the code itself to route scans through an analytics or redirect service. If your priority is clean, non-instrumented codes — for print, packaging, or offline material — this is the relevant tool on the site.

Relax Sound Board

A sound board for calming audio. It is a personal-utility tool rather than a professional one: something to run in a browser tab while working or resting. The site does not describe the specific sounds or any configuration options, so treat it as a simple play-and-listen page.

How to decide which one you need

  • You are building or auditing a web page: start with the Accessibility Cheatsheet for requirements, then the WCAG Color Contrast Tester for color decisions.
  • You need to produce a QR code without tracking: use the Tracking-free QR-Code Generator.
  • You want to encode text as Morse: use the Morse Code Generator.
  • You want background audio: use the Relax Sound Board.

All five are reachable from the "Project Highlights" section of the homepage, and the site also links to a full projects page. The blog is separate from these tools — recent posts cover topics like payment QR codes, the German Accessibility Strengthening Act (Barrierefreiheitsstärkungsgesetz), and a PeerTube Apple TV app — so if a tool is not what you need, the blog is the other place to look for related work.
