Overview

Mattermost is a collaboration platform aimed at teams that need secure, flexible communication and integrated workflows (messaging, voice/screen calls, automation, integrations). It supports self-hosting or cloud and is especially targeted at developer, operations and security teams.

If you’re running development, DevSecOps, incident response or any workflow where tool-integration, data control and security matter, Mattermost offers more control than many standard SaaS chat platforms. You can self-host, integrate directly with DevOps tools, run your own LLMs/AI agents, and keep tighter governance of your data.

You set up Mattermost as a server (either cloud or on-premises). Users join channels or direct messages, share files, search histories, use threaded conversations, initiate voice/screen-share calls. You can integrate third-party tools via plugins or APIs (GitHub, GitLab, Jira, ServiceNow, etc.).

FAQ

Can I use the output commercially or share files etc? ▼

Yes — you are using a collaboration platform; there's no “output” in the sense of generated content that has separate licensing. If you self-host, you control your data and usage. Ensure third-party plugins or integrations you add comply with your own licensing.

How many users or messages can I support? ▼

The free/open version has fewer enterprise features. For the Professional tier, the search capability is specified as “core search up to 3 million posts/files” in the pricing page. (Mattermost.com) For very large scale you may need the Enterprise edition.

Can I edit or customise what it generates? ▼

Yes — Mattermost supports extensive customisation: you can add branding, themes, plugins/apps, integrate APIs/webhooks, build bots/agents. But some advanced capabilities are in paid tiers.

Does it integrate with my tools (e.g., Jira, GitLab, ServiceNow)? ▼

Yes — it has pre-built integrations and plugin support for many DevOps/IT tools (GitHub, GitLab, Jira, ServiceNow, etc). (Mattermost.com)

Does the company train using my content? ▼

If you self-host, your data stays under your control. In cloud hosted setups you should review their privacy policy. The company emphasises that deployments can be in sovereign/air-gapped environments. (Mattermost Documentation)

What kind of support do I get on paid plans? ▼

On the Professional tier there is business-hours support (as per pricing page). (G2) On the Enterprise plan there is 24×7 support and faster response SLAs.

What extra do I get on the top plan versus the starter? ▼

Enterprise gives you advanced compliance, performance, governance features, custom admin roles, full SSO, air-gap/sovereign deployment options, high-availability clusters, 24×7 support. Starter gives basic messaging features and may lack advanced governance, SSO and scale features.
