About Activity-Relay
Activity-Relay is an open source ActivityPub relay server written in Go. It is designed for operators who want to run their own relay for fediverse servers. The software runs in three modes: an API server, a job worker, and a CLI management utility. It requires Redis.
The repository's setup notes explain how to connect other servers to a relay. Mastodon, Misskey, and their forks subscribe to the relay's /inbox address. Pleroma and its forks follow the relay's /actor address. Build, install, and control instructions are kept in the project's GitHub wiki.
Key features
- Separate API server, job worker, and CLI management utility run modes
- Requires Redis as a backing service
- Configuration through a YAML file or environment variables
- Optional relay name, domain, summary, icon, and image settings
- JOB_CONCURRENCY setting to control job concurrency
