Alternatives to Slack
Channels-based team chat.
- What is Slack?
- Slack is a team messaging app built around persistent channels, direct messages and third-party app integrations.
- What does it do?
- Organises work conversations into channels, threads and DMs with searchable history and file sharing, plus huddles for quick voice and video. Bots, app integrations and workflow automations push other tools into the same feed.
- Who is it for?
- Distributed teams and companies that want real-time chat instead of internal email. There is a free tier, but teams that rely on history and integrations end up on paid plans.
- What are the alternatives to Slack?
- Mattermost, Rocket.Chat and Zulip are open source and self-hostable; Zulip organises discussion by topic rather than a running channel feed, and Twist is built for asynchronous conversation.
