Feder
=====
One ActivityPub core, many runtimes.
Feder is an early-stage Rust project for building ActivityPub applications from
a portable protocol core and platform-specific runtimes.
Motivation
----------
Feder grew out of work in the Fedify ecosystem and a question about smaller,
cheaper, and more portable fediverse software. What would it take for a
single-user ActivityPub server to run outside the usual VPS-shaped web
application?
One long-term direction is embedded or device-like federation: not moving a full
Mastodon-style server onto a microcontroller, but decomposing ActivityPub
software so different parts can run on machines with very different resources.
Approach
--------
Feder separates ActivityPub protocol logic from platform execution. The core
should contain federation behavior such as inbox/outbox state, delivery
decisions, and protocol-level rules. Runtimes provide platform-specific pieces
such as networking, storage, clocks, scheduling, and execution.
The first target is a Linux proof of concept for a small single-user
ActivityPub server. Future runtimes may explore more constrained environments.
