Quick Answer: Microsoft Teams, Google Chat, and Discord are the top Slack alternatives in 2026. Teams integrates with Power Automate for 1,000+ connectors and is included in M365 plans.

Best Slack Alternatives for Workflow Automation in 2026
Slack's per-user pricing and limited free tier drive teams to evaluate alternatives. The key differentiator for automation is each platform's integration with workflow engines.
Top 5 Alternatives
| Tool | Starting Price | Automation Engine | Best For |
|---|---|---|---|
| Microsoft Teams | Included with M365 ($12.50/user) | Power Automate (1,000+ connectors) | Microsoft shops |
| Google Chat | Included with Workspace ($7.20/user) | Apps Script + AppSheet | Google shops |
| Zapier + any chat | $29.99/month | 7,000+ integrations | Cross-platform automation |
| n8n + Mattermost | Free (self-hosted) | Unlimited workflows | Self-hosted teams |
| Make + any chat | $10.59/month | Visual scenarios | Budget automation |
Microsoft Teams
Teams is the obvious alternative for Microsoft 365 organizations. Power Automate integration provides 1,000+ connectors with desktop RPA and AI Builder. Teams is included in M365 plans at no additional cost.
Google Chat
Google Chat integrates with Apps Script for custom automation and AppSheet for no-code workflows. Best for Google Workspace organizations that want chat integrated with Drive, Calendar, and Sheets.
Zapier as a Bridge
Zapier connects any chat platform to 7,000+ apps. Teams using Discord, Mattermost, or Rocket.Chat can add Zapier for automation capabilities comparable to Slack Workflow Builder.
n8n + Mattermost
For self-hosted teams, n8n (workflow automation) plus Mattermost (team chat) provides a completely free, self-hosted alternative to Slack with unlimited automation at zero per-user cost.
Editor's Note: We compared costs for a 50-person company. Slack Business+: $750/month. Microsoft Teams (with existing M365 E3): $0 additional cost. Google Chat (with Workspace Business Standard): $0 additional cost. n8n + Mattermost (self-hosted): $0 (server costs only, approximately $50/month). For organizations already paying for M365 or Google Workspace, the cost savings from dropping Slack are immediate.
