Best open-source alternatives to Google Workspace

Immich is a self-hosted photo and video management platform designed for people who want to control their media library without relying on a third-party cloud service. It provides a web interface and mobile apps for organizing, browsing, backing up, and sharing personal photo collections, with support for advanced features such as metadata search, facial recognition, albums, and public sharing. The project appears aimed at users who want a modern alternative to commercial photo storage services while keeping their data on infrastructure they manage. The README highlights mobile and web functionality, automatic backup behavior, offline support, and administrative user management, making it suitable for households, small groups, or anyone running a private media server.

TinyCld is a self-hosted workspace platform organized as an app shell plus separately installable feature packages. It is designed for users who want a modular alternative to a hosted productivity suite, with core capabilities such as mail, calendar, contacts, drive, text, calc, and import tooling assembled from sibling packages in a pnpm workspace. The project combines an Expo front end, PocketBase back end, and Go server wiring, with a generator that connects the installed packages into routes, seeds, migrations, and runtime configuration. It is aimed at developers or operators who want to assemble and run a customizable workspace locally or in a self-hosted deployment, with Docker-based delivery and a documented bootstrap flow for building a working workspace root.
