A better way to build features for your web app.

Mason provides front-end features for common product needs, like user registration, news feeds, SSO, two-factor authentication, and more. Tailor them to match your look and feel perfectly, or build a custom feature using common elements.

Drop your feature into your codebase — that’s it, you’re live.

You have complete strategic control.

Export your feature, grab a single line of code, and drop it into your existing codebase. Your Mason-built feature will show up exactly where you want it, and you can relocate or remove it whenever you want.
