Mastodon.py is a mature Python client library for the Mastodon social network API. It provides a comprehensive, type-safe interface to all Mastodon endpoints (statuses, accounts, timelines, notifications, admin, streaming, etc.) with built-in pagination, rate limiting, OAuth authentication, and version compatibility detection. The library is split across multiple modules that compose a single `Mastodon` class via inheritance, offering both synchronous and streaming access. It is extensively tested against a local Mastodon instance using VCR-recorded cassettes and supports optional features like WebPush notifications, blurhash decoding, and grapheme-based status length calculation. The codebase is well-maintained with modern Python packaging (pyproject.toml), type annotations, and support for Python 3.6 through 3.14.
Nextcloud Social is a federated social networking application implemented as a Nextcloud app. It allows each Nextcloud user to become an ActivityPub actor (Person), enabling posting, following, liking, boosting, replying, and direct messaging across the Fediverse. The system is fully compatible with the Mastodon client API, supporting timelines, lists, filters, scheduled posts, polls, stories, collections, trends, and moderation features. The backend is written in PHP, structured with controllers, services, database request builders, and ActivityPub model classes. The frontend is built with Vue 3, Pinia, and Vue Router, providing a responsive single-page application for timelines, profiles, and settings. The app integrates deeply with Nextcloud's dashboard, notifications, search, user migration, and admin settings. Federation is handled via ActivityPub protocols with HTTP signature verification, outbound delivery queues, and WebFinger discovery. The codebase is well-tested with both PHPUnit and Vitest suites, covering unit, integration, and federation wire compatibility tests.
