It's included with most Microsoft 365 plans, integrates deeply with Office apps, and handles video meetings well.

Voice channels are excellent, and it's free for most use cases.\n\n**Using Google Workspace?** Google Chat. Included with Workspace, integrates with Docs and Meet. More basic than Slack but gets the job done if you're in Google's ecosystem.\n\n**Need self-hosting?** Rocket.Chat. Open-source, deploy on your own servers.

Voice channels are excellent, threads work well, and it's free. Less polished than Slack but increasingly adopted by tech teams.\n\n**Google Workspace?** Google Chat. Not as good as Slack, but it's included and integrates with everything Google.
