Tranquil PDS#

A Personal Data Server for the AT Protocol.

Bluesky runs on a federated protocol called AT Protocol. Your account lives on a PDS, a server that stores your posts, profile, follows, and cryptographic keys. Bluesky hosts one for you at bsky.social, but you can run your own. Self-hosting means you control your data; you're not dependent on any company's servers, and your account + data is actually yours.

This particular PDS thrives under harsh conditions. It is a dandelion growing through the cracks in the sidewalk concrete.

It has full compatibility with Bluesky's reference PDS: same endpoints, same behavior, same client compatibility. Everything works: repo operations, blob storage, firehose, OAuth, handle resolution, account migration, the lot.

Another excellent PDS is Cocoon, written in go.

What's different about Tranquil PDS#

It is a superset of the reference PDS, including: passkeys and 2FA (WebAuthn/FIDO2, TOTP, backup codes, trusted devices), SSO login and signup, did:web support (PDS-hosted subdomains or bring-your-own), multi-channel communication (email, discord, telegram, signal) for verification and alerts, granular OAuth scopes with a consent UI showing human-readable descriptions, app passwords with granular permissions (read-only, post-only, or custom scopes), account delegation (letting others manage an account with configurable permission levels), automatic backups (configurable retention and frequency, one-click restore), and a built-in web UI for account management, OAuth consent, repo browsing, and admin.

The PDS itself is a single small binary with no node/npm runtime. It requires postgres. Blobs are stored on the local filesystem by default (S3 optional). Valkey is optional (supported as an alternative to the built-in cache).
