Mattermost: pros & cons
- Fully self-hostable, including in air-gapped environments
- Familiar channel-based interface
- Open source core
- Ecosystem of integrations is smaller than Slack's
- You carry the upgrade and backup burden
- Mobile apps lag behind commercial rivals
Zoom: pros & cons
- High Stability: Calls rarely drop even on poor-quality internet connections.
- Ease of Use: The simplest video tool for non-technical users to join and use.
- Screen Sharing: Multi-person screen sharing and whiteboard features are very advanced.
- Large Capacity: Can display hundreds of participants on screen simultaneously without lag.
- Free Plan Limits: The 40-minute limit on free group calls can be a major restriction.
- App Dependency: The web version is not as fluid as the dedicated desktop application.
- No Ecosystem: Does not offer a native chat/file ecosystem like Slack or Teams.
Our verdict on Mattermost
The right call when self-hosting is non-negotiable. Otherwise the convenience gap with hosted chat is wide.
Our verdict on Zoom
Still the best option for those prioritizing video quality and reliability above all else.
