Google Meet is the broader, more established team communication tool and wins for teams that want depth, integrations, and a mature ecosystem. Mattermost is the open-source, self-hostable alternative for teams that want data ownership and no per-seat lock-in. If you need maximum capability and ecosystem, choose Google Meet; if open-source control matters more, Mattermost is the better-value pick.

Messaging and channels
Google Meet is video calls in Google Workspace; Mattermost is open-source, self-hosted team chat. On raw capability and feature depth, Google Meet is the stronger of the two — it covers more of the team communication tool workflow out of the box and handles edge cases that Mattermost only reaches through workarounds or add-ons. Mattermost keeps a deliberately narrower surface area, which is a feature for teams that find broader tools cluttered. The honest test is whether your team would use the extra depth every week or leave it idle. Map your three most common team communication tool tasks against each product before deciding, because feature lists rarely predict daily fit.
Calls and meetings
For everyday usability and onboarding, Google Meet is the easier of the two to live with. Because Mattermost is open source and self-hosted, standing it up means provisioning servers, handling upgrades, and owning backups before the first user logs in. Both Google Meet and Mattermost reward teams that adopt their default workflow rather than fighting it. Adoption is where most team communication tool rollouts succeed or stall, so weigh who opens the tool every day — and how much training they will tolerate — more heavily than any single capability. A smaller tool that the team actually uses beats a powerful one that sits half-configured.
Admin and compliance
Mattermost wins on flexibility and control. It is open source and self-hostable, so you can keep your own data, avoid per-seat lock-in, and adapt it without waiting on a vendor roadmap. Google Meet is a managed, proprietary product — faster to adopt and less to maintain, but your data and workflow live on the vendor's terms. Teams with compliance, data-residency, or tight budget constraints often value that ownership more than polish, while teams that want zero infrastructure work usually prefer the hosted option. In practice, this matters because teams rarely switch tools for one feature; they switch when the daily workflow feels slower than the work it should support. Test one real use case in each before committing.
Pricing and value
On price, Mattermost is the better value for most teams. Google Meet offers a free plan; Mattermost is open source and free to self-host. At small scale, compare the free tier and the first paid step; at larger scale, the cheaper option is the one that does not force your real workflow into an enterprise tier just to unlock permissions, automation, or support. Google Meet can still win on total cost if it replaces other tools you already pay for, so price the whole stack, not just the per-seat sticker. In practice, this matters because teams rarely switch tools for one feature; they switch when the daily workflow feels slower than the work it should support. Test one real use case in each before committing.
Integrations and ecosystem
Google Meet has the broader ecosystem — more native integrations, a larger community, and more templates, guides, and people who already know it. Mattermost connects to the common tools but leans on open APIs and self-built connections for anything niche. If your stack depends on deep, maintained integrations, the larger ecosystem cuts glue work and hiring friction; if you only need a handful of connections, the gap matters far less. Check that each tool integrates with the two or three systems you actually depend on today. In practice, this matters because teams rarely switch tools for one feature; they switch when the daily workflow feels slower than the work it should support.

Pricing verdict: Google meet offers a free plan; Mattermost is open source and free to self-host. Google Meet has a free plan and Mattermost has a free plan. For most teams Mattermost is the lower-cost choice on the entry tiers. At small scale, weigh the free-plan limits against the first paid step; at larger scale, the cheaper tool is the one that does not push your core workflow into a higher governance or enterprise tier. Always confirm current pricing on each vendor's page before you commit.

Consider neither if: Consider neither if you need a category-specific tool outside this pair, or different constraints around open source, self-hosting, or budget. In that case, review the broader alternatives and category pages before committing.
