FAQ
Frequently asked questions
Is on.dev for sale?
Yes. on.dev is available for acquisition. You can make an offer through Namecheap or email the owner at joel@on.dev, and serious offers get a straight answer.
How does buying on.dev work?
Use the Make offer button on the on.dev listing at Namecheap, or email joel@on.dev directly. Once a price is agreed, the domain is transferred to the buyer's registrar account.
Why is a two-letter .dev domain valuable?
There are only 676 possible two-letter combinations on any extension, and very few of them are real words. on.dev is two characters, one syllable and an everyday English word, which makes it easy to say, type and remember.
What could on.dev be used for?
It fits almost any developer product: a deploy or hosting platform that gives every project an address like yourapp.on.dev, a feature flag service, an AI agent runtime, on-call and incident tooling, developer onboarding, or a conference and community brand.
Does a .dev domain need HTTPS?
Yes. The whole .dev extension is on the HSTS preload list built into major browsers, so every on.dev page and subdomain loads over HTTPS only. Hosts like Cloudflare, Vercel and Netlify issue certificates automatically.
Who owns on.dev?
on.dev is held by Foxe Labs, a small software lab that has published open-source WordPress plugins and PHP libraries since 2014.
