DenverCoder1/readme-typing-svg
⚡ Dynamically generated, customizable SVG that gives the appearance of typing and deleting text for use on your profile page, repositories, or website.
A PHP service that generates animated typing SVGs for GitHub profile READMEs — you hit an endpoint with query params, get back an SVG with a typewriter animation. Aimed squarely at the profile-readme crowd, not general web use.
The demo site with live preview is genuinely well done — you can tweak parameters and copy the URL immediately. The query-param API is simple and the option set covers the real use cases (multiline, pause, repeat, custom fonts via Google Fonts). PHPUnit test suite with SVG snapshot tests is more than most profile-readme tools bother with. Self-hosting path is documented and works.
It's a hosted service, so you're at the mercy of demolab.com uptime — your profile README breaks if the server goes down. The self-hosting docs still point to Heroku, which killed its free tier years ago. No rate limiting or caching headers documented, so popular profiles can hammer the server. The codebase is PHP, which is fine for what it is, but anyone wanting to fork and extend it is picking up a PHP project in 2026.
