About Sienna Accessibility Widget

Configuration for the Sienna Accessibility Widget lives in a sienna.config.js file. One independent developer, Benny Luk, builds and maintains it without VC funding, so the project depends on a single person. The same project offers free chat and cookie-consent widgets.
