1# Tranquil PDS
2
3A Personal Data Server for the AT Protocol.
4
5Bluesky 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.
6
7This particular PDS thrives under harsh conditions. It is a dandelion growing through the cracks in the sidewalk concrete.
8
9It 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.
10
11Another excellent PDS is [Cocoon](https://github.com/haileyok/cocoon), written in go.

13## What's different about Tranquil PDS
14
15This software isn't an afterthought by a company with limited resources.
16
17It is a superset of the reference PDS, including: passkeys and 2FA (WebAuthn/FIDO2, TOTP, backup codes, trusted devices), 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), and a built-in web UI for account management, OAuth consent, repo browsing, and admin.
18
19The PDS itself is a single small binary with no node/npm runtime. It does require postgres, valkey, and s3-compatible storage, which makes setup heavier than the reference PDS's sqlite. The tradeoff is that these are battle-tested pieces of infra that we already know how to scale, back up, and monitor.
