Register and own your own free, unique usernames for Bluesky

Skyname is a username registrar for Bluesky.

Bluesky uses domains as usernames. Since I own the domain darn.fish, I can set it as my username on Bluesky, hence why I am @darn.fish.

DNS, specifically a TXT record, is used for verifying domain ownership. Skyname hijacks this process and lets users verify a subdomain on a set of domain names owned by whoever runs a Skyname instance.

The official Skyname instance is located at skyna.me. You can find domains such as bsky.cool and bsky.lgbt among others. Anyone can sign up and claim their own .bsky.cool username for free and forever.

If you'd like to add your own domain for anyone to use, email [email protected] to start the process. Alternatively, and more preferrably, you can host your own instances and email [email protected] to be added to a list coming in the not so distant future.

Clone down the repo and install dependencies:

git clone [email protected]:darnfish/skyname.git
cd skyname
yarn

You will need to populate SKYNAME_CONFIG with a Base64 encoded JSON object to supply your owned domains and DNS providers. Here is a sample:

{
    "domains": {
        "example.com": {
            "provider": "my-provider",
            "zoneId": "<cf_zone_id>",
            "disallowedSubdomains": [
                "skyname"
            ]
        }
    },
    "providers": {
        "my-provider": {
            "service": "cloudflare",
            "token": "<cf_token>",
            "attestation": {
                "verified": true
            }
        }
    }
}

Once you have this file, save it to config.json and run the following command to copy the encoded Base64 string to clipboard so you can set as your SKYNAME_CONFIG environment variable:

cat config.json | base64 | pbcopy -

You will also need to set POSTGRES_URL to a PostgreSQL database. The database must have read write permissions and a table called registrations which can be created using the following SQL query:

CREATE TABLE "public"."registrations" (
    "id" varchar NOT NULL,
    "created_at" text NOT NULL DEFAULT now(),
    "invalidated_at" text,
    "actor" varchar NOT NULL,
    "subdomain" varchar NOT NULL,
    "domain" varchar NOT NULL,
    "previous_username" varchar NOT NULL,
    "record_id" varchar NOT NULL,
    "server" varchar NOT NULL DEFAULT 'bsky.social'::character varying,
    PRIMARY KEY ("id")
);

You can optionally set a TG_CHAT_ID and TG_BOT_TOKEN which will log events out to a Telegram chat.

To run the server locally, make sure you have added the above environment variables to .env.local in the repository root. Then you can run the following:

yarn dev
