What .dev is
A generic ending operated by Google, opened to everyone in 2019. Like .app, the entire namespace sits on the HSTS preload list, so HTTPS is mandatory rather than recommended.
Who it suits
Developer tools, documentation sites, personal engineering pages and open-source projects. Its audience is precisely the audience that will not misread it, which is the whole argument for a specialised ending.
The catch
It is unmistakably for developers. That is an asset while your audience is developers and a liability the day you start selling to their finance department. If the company might outgrow the ending, register the .com in the same breath and treat the .dev as the technical face rather than the address on the invoice.
Common questions
Is .dev restricted to developers?
No. Anyone can register one for anything; the meaning is conventional rather than enforced. Google opened it to general availability in 2019 with no eligibility check, and there is nothing to prove or apply for.
Does .dev require HTTPS?
Yes. The whole ending is HSTS-preloaded, so browsers will not load a .dev address over plain HTTP under any circumstances. A free certificate from your host satisfies it.
Can I use .dev for my company's main site?
You can, and plenty of developer-tools companies do. Just make the decision knowing the ending is a statement about who you are talking to, and hold the .com if you can so the choice stays reversible.
