What it does
Margin groups teams into spaces and topic-based channels, with direct messages and voice or video calls. Its Free tier supports up to 10 members and five call participants, while paid tiers add storage and capacity; the product offers European hosting and a self-hosting option.
Organize people and discussions
Margin's organization contains spaces for departments or project teams, with topic channels inside each space. Use a channel for announcements or planning, and keep one-to-one conversations in direct messages. Voice and video calls are included. The site describes optional Secret mode for end-to-end encrypted private and group chats; it is not the default mode.
Compare capacity before inviting a team
The pricing page lists a Free tier for up to 10 members and five call participants, with no file storage. Paid tiers raise member and call limits and add storage. The homepage says hosted data stays on European infrastructure and that teams can self-host with Docker Compose. No account, installation, or live call was tested.
