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:
