About Mattermost Oxide

Secure collaboration and agentic workflows for mission-critical teams

Requires Mattermost Server v11.7.0+. Older servers may not be able to connect or have unexpected behavior.

-------

Mattermost is the leading collaborative workflow platform for defense, intelligence, security, and critical infrastructure. The platform runs on-premises and in private clouds. Mattermost Oxide is a rebuilt Mattermost mobile app, designed for better reliability and a smoother experience than the current app. It runs alongside the main Mattermost app and connects to your existing Mattermost server.

This is an early version: expect frequent changes between releases.

With Mattermost Oxide you can:

- Securely message your team in channels, direct messages, and group conversations.

- Keep critical workflows moving with Playbooks.

- Work with Mattermost Agents to bring AI into your conversations and workflows.

- Start 1:1 and group voice calls without leaving Mattermost.

- Ensure private mobility with ID-only push notifications to keep sensitive data protected while keeping stakeholders informed.

We ship updates frequently, and your feedback shapes what comes next: use Send Feedback in the ⋯ menu on the main screen.

To use this app, you need a URL for a Mattermost server.
