frii.site
A modern, free subdomain service for developers, project managers, and regular people.
Always free
frii.site will always be completely free for anyone to use. Our main goal is to provide free domains to users who are unable to buy their own domains. However, even if you do own a domain, you're welcome to use our service!
Support for many services
frii.site supports many popular services, such as Vercel. Most services that simply require a domain are supported, but certain services such as Cloudflare DNS require you to register your own domain.

You can register, delete, and modify domains straight from our dashboard. There is no need to use a convoluted CLI or a request form, and you don't have to wait for any domain verification as domain registrations are done immediately.
Completely open-source
Our frontend and backend are both completely open-source, and open to contributions. Our backend uses FastAPI, MongoDB, and fully-typed Python code, which makes it easy for other developers to quickly jump into our codebase. Our frontend is written in Svelte (with TypeScript).
