.dev domains
Operated by Google Registry and launched to the public in February 2019, .dev was one of the most anticipated domain extensions in the developer community. Google had privately held the extension for years before opening it for general registration. A defining technical feature of .dev is its inclusion on the HSTS preload list built into all major browsers, which means every .dev domain must be served over HTTPS — plain HTTP connections are automatically blocked. This makes .dev one of the few TLDs with a browser-enforced security requirement baked in by default.
The .dev domain is the go-to extension for software developers, engineering teams, and technology projects. Operated by Google Registry, it carries strong recognition in the developer community and signals a technical identity at a glance. Every .dev site is required to use HTTPS by default — a built-in security feature enforced by all major browsers — making it a natural fit for projects where security and professionalism matter. Whether you are building a personal portfolio, launching an open-source project, or shipping a developer tool, .dev is one of the most credible and recognizable choices available.

Who uses .dev
Developer Portfolios
A natural and instantly recognizable home for showcasing projects, skills, and code samples to potential employers and collaborators.
Open-Source Projects
Gives open-source libraries, frameworks, and tools a dedicated domain that clearly communicates a technical identity to contributors and users.
SaaS & Developer Tools
Ideal for APIs, SDKs, CLIs, and software products marketed directly to engineering teams and technical decision-makers.
Engineering Blogs & Docs
A credible home for technical writing, tutorials, and documentation sites where the .dev extension reinforces the subject matter.
Side Projects & Experiments
A clean, low-cost way for developers to give personal experiments and hobby projects a professional-looking address.
Naming guidance
Keep the name before .dev short, lowercase, and easy to type without autocorrect interference — developer audiences tend to type URLs directly. Hyphens are acceptable in the developer context but a single clean word or phrase is preferable. Make sure your SSL certificate is in place before pointing DNS, as the HSTS requirement means an unconfigured domain will be inaccessible in all major browsers.

.dev vs the alternatives
When to choose a different extension instead.
Choose .io for a startup or tech product where broader consumer audiences will also visit and the .io brand identity resonates beyond a purely developer-focused context.
Choose .app for a consumer-facing mobile or web application where the .app extension communicates the product type directly to end users.
Choose .tech for a technology company or conference where the audience includes both technical and non-technical stakeholders.
Choose .codes for a coding-focused project or educational platform where a more literal domain-hack style is preferred over the cleaner .dev identity.
Choose .sh for a command-line tool, shell script project, or infrastructure-focused product where the Unix shell association adds contextual meaning.
