pump.io is a self-hosted social network server built on Node.js that exposes an ActivityStreams JSON API for posting, following, and federated social activity. It ships with a web UI and can also serve as an activity stream backend for other applications.
Use cases
- self-host a federated social network
- add an activity stream feed to an existing app
- experiment with decentralized social software
- run a microblogging server with an ActivityStreams API
- post text, images, audio, and video to followers
When to choose
- you want a self-hosted, federated social server with a documented ActivityStreams API
- you need activity-stream functionality embedded in another application
- you want to experiment with decentralized social software
When to avoid
- you need ActivityPub federation with Mastodon and the wider fediverse
- you want a modern, actively developed social platform with a large ecosystem
- you need a hosted social network without server administration
