Google Chat is Google's instant messaging service, primarily aimed at organizations using Google Workspace. It works inside Gmail and Google's suite of productivity tools, making it a natural fit for teams already invested in Google's ecosystem. The product focuses on direct messages, group conversations, and integration with Google Meet, Docs, and other Workspace apps. It's free for personal users and included in most Workspace plans, which makes adoption straightforward for existing Google customers.
Teams considering Google Chat typically fall into two categories: those already standardized on Google Workspace who want messaging without switching platforms, and smaller organizations that prefer not to pay extra for a dedicated chat tool. The product handles day-to-day conversation threading, file sharing through Google Drive, and task management hooks into Google's calendar and contacts. It doesn't position itself as a standalone communication platform—it's designed as an integrated component of the broader Workspace experience, so buyers comparing alternatives are usually either moving away from Google entirely, need chat features Google Chat doesn't provide, or want the independence of a non-Google platform.

Slack and Microsoft Teams dominate enterprise messaging, while Missive, Twist, and Discord serve different niches—Missive for team inbox consolidation, Twist for async-first teams, and Discord for communities. Rocket.Chat and Mattermost are open-source options if you need self-hosting or data residency control.
Discord and Rocket.Chat offer strong free tiers with unlimited message history. Missive provides a free plan for small teams, and Element (Matrix-based) is open-source and free to self-host, though the hosted version has costs.
If you need Microsoft integration, Teams is the obvious choice. If you want Slack-like polish without vendor lock-in, Rocket.Chat or Mattermost work well. For focused, less noisy conversations, Twist is better than Slack.
Self-hosted platforms like Rocket.Chat, Mattermost, and Element give you complete data control. If you require cloud hosting, Missive operates in EU-compliant infrastructure, and Discord allows you to host on your own server with self-hosted gateway options.
Slack and Teams handle 5,000+ person deployments out of the box with fine-grained permissions. Rocket.Chat and Mattermost scale well too, but require more administration. Missive and Twist are better for smaller, focused teams (under 100 people).
Yes—Rocket.Chat, Mattermost, and Element are fully self-hostable. Slack, Microsoft Teams, Google Chat, and Discord are cloud-only, though Discord allows some gateway self-hosting for bots and integrations.
All eight products offer integrations, but breadth differs. Slack has 2,000+ apps. Teams integrates deeply with Office 365. Rocket.Chat and Mattermost support webhooks and API-driven integrations. Missive connects email inboxes alongside chat.
Twist is explicitly designed for asynchronous, threaded communication to reduce constant notifications. Missive combines chat with email and task management to consolidate where your attention goes. Mattermost and Rocket.Chat let you customize notification rules granularly.
