Hey DEV! I'm Stefan — TYPO3 dev, and I just launched a page of free browser tools
Hey, I'm Stefan I'm a freelance web designer & developer based in Klagenfurt, Austria — though these days most of my work happens for clients well beyond Austria's borders.

Stefan, a freelance web designer and developer based in Klagenfurt, Austria, has launched a webpage featuring free browser tools on his site. Stefan's focus is on TYPO3, handling the development and maintenance of end-to-end websites. In addition to coding, he also handles graphic design and video editing.
Stefan built a set of tools to replace multiple websites with ads. They include a Palette & Contrast Checker for accessibility, an Icon & Favicon Generator, a Web Image Optimizer, and CSS and JS Minifiers. The SEO & Performance Check tool provides a URL-based on-page SEO report and Google PageSpeed metrics.
All the tools run client-side, meaning that no data leaves the browser. The development process involved bilingual UX, client-side file processing, and the use of libraries like Terser, csso, pdf-lib, and pdf.js. Stefan discovered the importance of security headers, structured data, and easy SEO improvements after running his own SEO tool against his website. He invites readers to explore the tools, provide feedback, and consider freelance work or collaborations.
