What are the best alternatives to Slack?
The main alternatives to Slack covered here are Notion, Confluence, Google Workspace and Lark. Notion may suit teams that want a flexible wiki with a light project layer, while Confluence may suit teams that already use Jira and want connected documentation. None is best for everyone: the right collaboration tool depends on team size, budget and which Slack limitation you are trying to solve.
Teams usually start looking beyond Slack for documented reasons: per-user pricing grows quickly with team size, and external guests can add to cost; the Free plan limits message history to 90 days and integrations to 10. Slack remains a reasonable fit for teams that want real-time channel-based communication, so an alternative is not automatically better, only different.
Below, every option is compared with Slack in one table, then described with its strengths, trade-offs and pricing, each taken from its own sourced profile. Anything the sources do not document is marked as unknown.
Why teams look for Slack alternatives.
Each reason is a limitation documented on the Slack profile, with its source cited there.
Cost and pricing
Per-user pricing grows quickly with team size, and external guests can add to cost.
Free plan limits
The Free plan limits message history to 90 days and integrations to 10.
AI and models
Advanced AI needs Business+, so teams on Pro get only basic AI features.
Scope and fit
Many connected apps charge separately, which raises total cost.
According to its profile, Slack may be less suited to: teams that need long-term documentation rather than chat history; very cost-sensitive teams that need unlimited history and many integrations for free.

How to switch from Slack.
Moving off Slack usually means exporting messages, pages and files, checking how links, mentions and permissions survive the import, and rebuilding integrations and bots. Agree a cut-over date so conversations do not split across two tools. Move one team and its everyday channels or spaces into each shortlisted tool for two weeks.
- Export a sample of your Slack data and test an import into the new product.
- List the automations, integrations and permissions you would need to rebuild.
- Compare total cost for your real seat count, including add-ons and onboarding fees.
- Pilot with one team before a full cut-over.
- Check contract terms, renewal dates and notice periods with Slack.

Slack alternatives: questions and answers
What is the best alternative to Slack?
No single alternative is best for everyone. The alternatives covered here are Notion, Confluence, Google Workspace and Lark.
