Pump.io is written in
Node.js and uses
Activity Streams as the format for commands and to transfer data via a simple
REST inbox API. The software package also uses a
NoSQL database such as
MongoDB or
Redis, and requires
GraphicsMagick for uploading media. Pump.io can easily be run on hardware with less resources, such as a
Raspberry Pi or any other
single-board computer. It can be used either with the included Web UI, or other clients via its
API. As a federated social network, pump.io is not tied to a single site. Users across servers can subscribe to and communicate with each other, and if one or more individual nodes go offline the rest of the network remains intact.
ActivityPump ActivityPump is the protocol used by pump.io to allow for federation of user content between different pump.io instances. Compared to
OStatus, its microblogging-oriented predecessor, ActivityPump uses the
Activity Streams format and its vocabulary to allow for more general interactions between users, as well as to make development of alternative ActivityPump-based social networks easier for software developers, who were forced to operate within the limits of OStatus and its core technologies. == Standardization ==
