ALTCHA provides privacy-first spam protection with a globally compliant and accessible alternative to CAPTCHAs. Protects against spam and abuse without tracking users, complying with GDPR, CCPA, and other regulations while ensuring a frictionless experience.

Every chart in this project relies solely on semantic markup — table based — and a spread of CSS variables carried by the tags. No JavaScript required for display, and styles are progressively enhanced depending on your browser's capabilities.

CUBE CSS is a CSS methodology that’s orientated towards simplicity, pragmatism and consistency. It’s designed to work with the medium that you’re working in, often the browser, rather than against it.
