Tests Status Deploy Status badge-domains

Due to numerous nonsensical domain requests since the creation of this repository, I have temporarily restricted interactions to previously contributed developers.

Free subdomains for personal sites, open-source projects, and more. Here is a list of supported domain names:

Domain name Features
⚑ * cf dnssec ssl
⚑ * cf dnssec

Wildcards (like * are supported too, but the reason for their registration should be very clear and described in detail. Open an issue before the wildcard subdomain request with a clear description.


First of all, I want to answer one important question - "Why are you giving out domains for free?". Because sometimes I need domains for my pet projects, and instead of buying new domains every time, I decided to buy one for everyone, and use subdomains. And why not share them with the community?

Please, register domains only for existing projects - empty or misconfigured sites will be removed after some time (I do it manually, with notifications before the cleaning).

  3. Edit it (below is just an example, provide a valid JS file with your needs):
// for more details watch the file `./domains.d.ts`

  description: '...', // describe your project in this field
  domain: '', // aka "root-domain". select between '' and ''
  subdomain: 'foobar', // desired subdomain name
  owner: {
    repo: '<https://URL/to/the/repository/with/your/project/sources/if/it/is/public>',
    email: '<your-public@email.address>',
  record: {
    CNAME: '<cname-domain>', // e.g.: <your-github-account>
    TXT: ['list', 'of', 'required', 'txt', 'records'],
    A: ['list', 'of', 'IPv4', 'addresses', 'like', 'a', ''],
    AAAA: ['list', 'of', 'IPv6', 'addresses', 'like', 'a', '::1'],
    NS: ['list', 'of', 'nameservers'],
  //proxy: false, // disable Cloudflare proxy (with is enabled by default). In this case, your origin server
                  // should provide valid a SSL certificate and protection CF will be disabled

  //   subdomain: 'foo',
  //   record: {
  //     CNAME: '...',

⚠ To validate the project domain, registered on the Vercel platform - please, provide full information about the required verification records in the PR description or separate issue. I need to add them to the DNS zone manually. A correct PR example can be found here.
