Note: See updated post from May 2025 describing a newer, cheaper, easier to run relay implementation! These are some informal notes on setting up a full-network atproto Relay, using the bigsky relay software developed by Bluesky. This is the same software we run ourselves at https://bsky.network.

A Full-Network Relay for $34 a Month | bryan newbold
This is an update to a Summer 2024 blog post. At the time, atproto relays required a cache of the full network on local disk to validate data structures. With the Sync v1.1 updates, relays don't need all that disk I/O. What impact does that have on hosting setup and operating costs? Turns out the d...
What is atproto?
What is atproto? atproto is two things: A protocol for creating open social networks An open social network atproto, the open social network Today the atproto network has 36+ million users and powers Bluesky and a handful of other apps. Almost all atproto data is public. Content like posts, likes, follows, and photos/videos are publicly accessible to any network participant in a permissionless way. As an example of how open the network is, here’s how easy it is to stream all public data on the network using a public atproto Relay like bsky.network:

Introducing Bluesky Protocol Services
atproto.com@metaflame.dev gave a great explanation in this mini-thread of the advantages for the #atproto network in having multiple, independent relays operating

Redundancy, resilience, and possibly distance Importantly, once enough independent relays are active, they are likely to disincentivize malicious behavior for any one of them. Having multiple implementations (that is, different code) adds further resilience.
