Welcome to the repository for the official Bluesky PDS (Personal Data Server). This repository includes container images and documentation designed to assist technical people with self-hosting a Bluesky PDS.
Head over to the AT Protocol PDS Admins Discord to get started!

Bluesky is a social media application built on AT Protocol.
Please visit the Bluesky website for more information.
The Authenticated Transfer Protocol, aka atproto, is a protocol for large-scale distributed social applications.
Please visit the AT Protocol docs for additional information.
As of Feb, 2024, the AT Protocol PDS (Personal Data Server) is now open to federation for self-hosters!
✅ Federated domain handles (e.g. @nytimes.com)
✅ Federated feed generators (custom algorithms)
✅ Federated relays (event firehose)
✅ Federated app views (API service)
✅ Federated data for self-hosters (PDS hosting)
✅ Federated moderation (labeling)
🚧 Federated data for large service providers (coming soon)
Developers may now run self-hosted PDS hosts on the production network!
Though it is still recommended to run experiments in the developer sandbox network.
Read the SANDBOX.md for an overview of the sandbox network.
Self-hosting a Bluesky PDS means running your own Personal Data Server that is capable of federating with the wider Bluesky social network.
Important
Initially to join the network you'll need to join the AT Protocol PDS Admins Discord and register the hostname of your PDS. We recommend doing so before bringing your PDS online. In the future, this registration check will not be required.
Launch a server on any cloud provider, Digital Ocean and Vultr are two popular choices.
Ensure that you can ssh to your server and have root access.
Server Requirements
- Public IPv4 address
- Public DNS name
- Public inbound internet access permitted on port 80/tcp and 443/tcp
Server Recommendations
| Operating System | Ubuntu 22.04 |
| Memory (RAM) | 1 GB |
| CPU Cores | 1 |
| Storage | 20 GB SSD |
| Architectures | amd64, arm64 |
| Number of users | 1-20 |
Note: It is a good security practice to restrict inbound ssh access (port 22/tcp) to your own computer's public IP address. You can check your current public IP address using ifconfig.me.
One of the most common sources of misconfiguration is not opening firewall ports correctly. Please be sure to double check this step.
In your cloud provider's console, the following ports should be open to inbound access from the public internet.
- 80/tcp (Used only for TLS certification verification)
- 443/tcp (Used for all application requests)
Note: there is no need to set up TLS or redirect requests from port 80 to 443 because the Caddy web server, included in the Docker compose file, will handle this for you.
From your DNS provider's control panel, set up a domain with records pointing to your server.
| Name | Type | Value | TTL |
|---|---|---|---|
example.com |
A |
12.34.56.78 |
600 |
*.example.com |
A |
12.34.56.78 |
600 |
Note:
- Replace
example.comwith your domain name. - Replace
12.34.56.78with your server's IP address. - Some providers may use the
@symbol to represent the root of your domain. - The wildcard record is required when allowing users to create new accounts on your PDS.
- The TTL can be anything but 600 (10 minutes) is reasonable
Use a service like DNS Checker to verify that you can resolve domain names.
Examples to check (record type A):
example.comrandom.example.comtest123.example.com
These should all return your server's public IP.
On your server via ssh, download the installer script using wget:
wget https://raw.githubusercontent.com/bluesky-social/pds/main/installer.shor download it using curl:
curl https://raw.githubusercontent.com/bluesky-social/pds/main/installer.sh >installer.shAnd then run the installer using bash:
sudo bash installer.shTip
The most common problems with getting PDS content consumed in the live network are when folks substitute the provided Caddy configuration for nginx, apache, or similar reverse proxies. Getting TLS certificates, WebSockets, and virtual server names all correct can be tricky. We are not currently providing tech support for other configurations.
You can check if your server is online and healthy by requesting the healthcheck endpoint.
You can visit https://example.com/xrpc/_health in your browser. You should see a JSON response with a version, like:
{"version":"0.2.2-beta.2"}
You'll also need to check that WebSockets are working, for the rest of the network to pick up content from your PDS. You can test by installing a tool like wsdump and running a command like:
wsdump "wss://example.com/xrpc/com.atproto.sync.subscribeRepos?cursor=0"Note that there will be no events output on the WebSocket until they are created in the PDS, so the above command may continue to run with no output if things are configured successfully.
Using ssh on your server, use pdsadmin to create an account if you haven't already.
sudo pdsadmin account createUsing ssh on your server, use pdsadmin to create an invite code.
sudo pdsadmin create-invite-codeWhen creating an account using the app, enter this invite code.
You can use the Bluesky app to connect to your PDS.
- Get the Bluesky app
- Enter the URL of your PDS (e.g.
https://example.com/)
Note: because the subdomain TLS certificate is created on-demand, it may take 10-30s for your handle to be accessible. If you aren't seeing your first post/profile, wait 30s and try to make another post.
It is recommended that you keep your PDS up to date with new versions, otherwise things may break. You can use the pdsadmin tool to update your PDS.
