Collaborate and communicate

Team chat, video meetings, files, documents, wiki and e-signature.

This use case is not yet reviewed: it names services or facts that are not yet verified. It is shown labelled and is not indexed.Review note: Microsoft 365, Microsoft Teams, Slack, Zoom, Google Meet, Google Drive, Dropbox and Notion have no verified relation to a catalogued project yet.

Problems it solves

  • Chat, meetings, files and documents each come with their own subscription and admin.
  • Shared files and documents should stay under your control and in a location you choose.
  • You need to decide yourself how long chat and meeting history is kept.
  • Everyone in the organisation needs the basics, so per-user prices add up fast.

Services it can replace

Each row shows our relation records with their status and evidence. A service without a verified relation says so.

Limitations

  • Our relation record classes BookStack as a partial replacement for Confluence, based on BookStack's own Confluence page. Check the features your teams use every day.

    From a relation record · BookStack · VerifiedSource

  • Nextcloud is licensed AGPL-3.0, a network copyleft licence: modified versions offered over a network must be shared with their users.

    From the project's record · Nextcloud · VerifiedSource

  • No office suite (documents, spreadsheets, presentations) is in the curated catalogue yet, so this page cannot yet point to a reviewed replacement for Microsoft 365 or Google Docs.
