.app
The .app domain is a generic TLD operated by Google Registry, launched in May 2018. Like .dev, it enforces HTTPS through the HSTS preload list, ensuring all .app sites are secure by default. Designed for application developers and software companies, it provides a clean, recognizable URL for mobile apps, web apps, and software products. Cash.app by Square (now Block) is one of the most prominent examples. The extension is popular with indie developers, startups launching new products, and established companies creating dedicated app landing pages. Its Google backing, security-first approach, and clear semantic meaning make it a strong choice for anything app-related.
