What is a .dev domain?
The .dev domain is a generic top-level domain (gTLD) managed by Google Registry and was launched in February 2019. What's special about .dev is that it was the first domain extension to require HTTPS by default via HSTS preloading. This means every .dev website automatically enforces a secure connection, benefiting both security and visitor trust.
Google developed .dev specifically for the developer community. The extension is intended for software developers, development agencies, open-source projects, developer tools, and technical portfolios. Major tech companies such as Google itself (web.dev), GitHub, and countless developers have adopted .dev as their professional online address.
Since its launch, hundreds of thousands of .dev domain names have been registered by developers worldwide. The extension has built a strong reputation as the standard for the developer community, similar to how .edu is associated with education and .gov with government institutions.
Benefits of a .dev domain
- Built-in HTTPS security - Thanks to HSTS preloading, every .dev website is secured with HTTPS by default, without manual configuration. This is a unique security advantage over most other extensions.
- Clear developer identity - A .dev domain immediately communicates that you're a developer, agency, or technical project, ensuring instant recognition with your target audience.
- Google Registry quality - With Google as registry manager, you benefit from a robust, reliable infrastructure and strict security standards.
- Excellent SEO opportunities - The mandatory HTTPS connection provides a small but relevant SEO advantage, since Google considers HTTPS a positive ranking factor.
- Professional and modern - The .dev extension radiates technical expertise and modernity, ideal for building a strong personal or company brand in the tech sector.
- Good availability - As a relatively new extension, .dev still offers plenty of choice among short, relevant domain names that are long since taken on .com.
