Cloud & Collaboration

Cloud & Collaboration here has a clear center of gravity: tools for teams that want modern teamwork without giving up control of their infrastructure, data, or workflows. You’ll find private file-sharing and workspace platforms like Seafile, ownCloud, and Nextcloud; browser-based office suites and editors such as Collabora Online, ONLYOFFICE, CryptPad, and Etherpad; and communication tools including Mattermost, Rocket.Chat, and Jitsi. Many of these projects are open source and self-hostable, with attention to permissions, auditability, compliance needs, encrypted or private collaboration, and deployment in sensitive environments like government, healthcare, defense, and critical infrastructure.

The subcategory also stretches into the collaboration layers that software and product teams rely on every day. Forgejo, Gitea, Codeberg, and GitLab cover code hosting, issue tracking, CI/CD, project coordination, and DevSecOps workflows, while Penpot brings designers and developers together around UI layouts, prototypes, design systems, and handoff. The Eclipse Foundation adds a broader open-source ecosystem for projects, specifications, working groups, and developer resources. Taken together, these listings are especially useful if you’re looking for alternatives to standard SaaS workspaces: tools you can run yourself, integrate into existing systems, or choose because privacy, governance, and long-term openness matter to your team.
