HumHub
Workplace and Yammer's pattern on your own server, with GDPR compliance by construction rather than contract: HumHub is an open-source enterprise social network from Germany. Built in PHP on Yii2, it organizes everything around four concepts. Users get rich profiles with follows and interactions. Spaces are the structural unit - rooms for departments, projects, events, or clubs, with per-Space permissions, notification settings, and email summaries, and operators can auto-map users into the right Spaces. Content covers posts, wiki pages, photos and video, events, and tasks, with multi-level comments, versioning, archiving, moderation reporting, and filterable full-text search across everything. Modules make it a platform: roughly 80 install-and-activate extensions including Calendar, Wiki, Polls, Tasks, Gallery, News, direct-message Mail, OnlyOffice document editing, Advanced LDAP, SAML and JWT SSO, a RESTful API, mass user import, Translation Manager, and a Theme Builder with custom pages - every one optional and toggleable at runtime. That module economy is why HumHub serves such varied deployments: corporate intranets, city governments, universities, political parties, and nonprofits all configure the same core differently. Requirements are a plain LAMP stack - PHP 8.1+ and MySQL/MariaDB - making it one of the easiest community platforms to operate long-term.

Go wild creating snazzy, sophisticated chat apps atop the mighty Matrix. Part of a bustling bazaar of clients, servers, and robotic minions (we mean bots), this open-source extravaganza is snugly housed on RepoCloud, where your wallet won't weep over hosting fees. So, whether you're itching to gab, code, or conquer the universe of decentralised discourse, Matrix is your trusty sidekick in the quest for communication liberation!
GoToSocial
Mastodon serves single-user and small-community instances poorly; GoToSocial, an ActivityPub server written in Go, was built precisely for them. Where Mastodon demands Ruby, PostgreSQL, Redis, and Sidekiq, GoToSocial is one binary using roughly 250-350 MiB of RAM with SQLite as the default database (PostgreSQL optional) - it runs comfortably on a $5 VPS or a repurposed laptop. The deliberate design choice is having no built-in web client: the server exposes profile pages, a settings panel, and a faithful implementation of the Mastodon API, and you post through the client app you already like - Tusky on Android, Feditext on iOS, Pinafore or Phanpy in the browser. Federation is the point: your instance follows, boosts, and replies across Mastodon, Misskey, Pixelfed, and the rest of the Fediverse, with your identity anchored to your own domain. Safety is a stated focus, with granular per-post visibility and interaction controls, content warnings, custom emoji, hashtag following, domain allow/blocklists, and OIDC login support. Built-in Let's Encrypt provisioning simplifies the mandatory TLS. AGPL-3.0 licensed and in active beta, federating cleanly with the ecosystem's major servers.
Oxigen
The social preview cards shown when links hit Twitter, LinkedIn, Slack, or Discord, generated on the fly: Oxigen is a small Go service for dynamic Open Graph images, no designer required per page. Instead of exporting static images per page, you compose a card once and drive it with parameters: title, author, website, logo, background image, and background dimming all arrive as URL query arguments, so your og:image meta tag simply points at the Oxigen endpoint with the page's own values substituted in. Every blog post, product page, and doc gets a branded, correctly sized preview generated on the fly. A built-in web UI covers interactive composition - tweak the text and imagery, watch the preview update, copy the resulting URL - while the same rendering path serves programmatic API use from static site generators, CMS templates, or build pipelines. Rendering is pure Go using the gg 2D graphics library, freetype fonts, and the imaging package, built on the kyoto framework by that project's author. Deployment is one stateless container on port 80 with no database and no external dependencies, so instances scale and restart freely.
