While powerful, Slack's pricing at $8.75/user/month for Pro can add up quickly for growing teams.

Why Look for Slack Alternatives?
Many teams find Slack's pricing hard to justify, especially when they're not using advanced features. The 90-day message history limit on free plans forces upgrades. Some teams prefer simpler tools that don't require constant attention.

Tips for Switching from Slack
Slack alternatives: common questions
How do I export my Slack messages before switching?+
Workspace owners and admins can export data from Slack's settings under Administration > Workspace settings > Import/Export Data. Free workspaces can only export public channel messages, while paid plans can export everything including DMs and private channels. The export comes as JSON files that you'll need to convert or import into your new platform.
What do I lose if I switch from Slack to a free alternative?+
You'll likely lose some advanced integrations, as Slack has the largest app directory with 2,600+ apps. Features like Canvas documents, workflow builder, and enterprise-grade security controls are also Slack-specific. However, most free alternatives cover the basics: messaging, file sharing, video calls, and common integrations like Google Drive and GitHub.
Is Slack's free tier enough for a small team of 5-10 people?+
It depends on how much you rely on message history. The 90-day limit means older conversations disappear, which can be frustrating for onboarding or referencing past decisions. If you're disciplined about documenting important info elsewhere (like Notion or Google Docs), the free tier works fine for basic daily communication.
Which Slack integrations are hardest to replace?+
Custom workflows and bots built with Slack's API are the hardest to migrate since they're platform-specific. Most standard integrations (GitHub, Jira, Google Calendar, Zoom) are available on alternatives like Discord, Mattermost, or Rocket.Chat. Check your alternative's integration directory before switching if you rely heavily on specific tools.
How much does Slack actually cost for a growing team?+
At $8.75/user/month for Pro (billed annually), a 20-person team pays $2,100/year, and a 50-person team pays $5,250/year. The Business+ plan at $15/user/month costs even more. These costs are per active user, so you can't share accounts, and they add up quickly as you hire.
