Slack vs Google Chat: Cost, Features, and Which Workspace Wins in 2026
If you already use Google Workspace, Chat is included. Is paying an additional $8.75+/user/month for Slack worth it? Here is the honest analysis.
Quick Verdict
If you have Google Workspace, Chat is included and is good enough for most basic team communication. Slack is worth the extra cost if you need deep third-party integrations (2,600+ vs Google ecosystem only), advanced workflow automation, or Slack Connect for external collaboration. For developer and engineering teams, Slack is significantly stronger.

| SSO | Business+ ($12.50+) | All plans |
| Integrations | 2,600+ | Google ecosystem + limited 3rd party |
| Video calls | Huddles (50) | Meet (100-500) |
| Storage | 10-20 GB/user | 30 GB-5 TB/user |
| Message history | Unlimited (paid) | Unlimited |
Where Google Chat Excels
Deep Google integration
Native file sharing from Drive, inline document collaboration, Calendar integration, and Meet video calls from within Chat.
Simpler interface
Less cluttered than Slack. Spaces (Google's version of channels) are straightforward. Good for teams that want basic communication without complexity.
Included in Workspace
No additional cost if you already use Gmail, Drive, Docs, and Calendar. Chat is simply there.
Strong search
Google's search expertise extends to Chat. Finding messages and files is fast and accurate.
Where Slack Excels
2,600+ integrations
Slack connects to virtually every SaaS tool: GitHub, Jira, Salesforce, Asana, PagerDuty, and thousands more. Google Chat's ecosystem is much smaller.
Channel organisation
Slack's channel system is more mature with threads, bookmarks, canvas, and pins. Better for organising conversations in large teams.
Workflow Builder
Slack's no-code automation tool lets non-technical users build workflows. Google Chat's automation relies on Google Apps Script, which requires coding.
Slack Connect
Communicate with external organisations directly in Slack channels. Google Chat's external collaboration is limited to guest access.
The Hybrid Approach
Some teams use both: Google Chat for quick Google-integrated communications and Slack for cross-tool workflows. This can work if you have clear boundaries (e.g., Chat for internal team chat, Slack for external collaboration and engineering).
However, the cost adds up: a 100-person team would pay $8,700/year for Slack Pro (annual billing) on top of their existing Workspace costs. And fragmented conversations across two platforms reduce productivity. Most teams are better off choosing one and committing to it.
Frequently Asked Questions
Is Google Chat free?
Google Chat is included with all Google Workspace plans, starting at $7 per user per month for Workspace Starter. It is not available as a standalone free product for business use (the consumer version has limited features). If you already pay for Google Workspace, Chat costs nothing extra. If not, you are paying at least $7/user/month for the full Workspace suite that includes Chat, Drive, Meet, and more.
Is Slack better than Google Chat for developers?
Significantly. Slack has 2,600+ integrations including deep connections with GitHub, GitLab, Jira, PagerDuty, CircleCI, and most CI/CD tools. Google Chat has far fewer third-party integrations and relies mainly on the Google ecosystem. Slack's Bolt SDK also makes building custom bots and integrations much easier. For engineering teams, Slack's integration ecosystem is a major advantage.
Can I use both Slack and Google Chat?
Yes, some teams run both: Google Chat for quick, Google-integrated communications (sharing Drive files, scheduling via Calendar) and Slack for cross-tool workflows and developer operations. However, this fragments conversations and doubles communication tool costs. Most teams are better off standardising on one platform unless specific integration requirements demand both.
Does Google Chat have AI features?
Yes. Google has integrated Gemini AI into Workspace, including Chat. Gemini can summarise conversations, help draft messages, and assist with information lookup. Unlike Microsoft Copilot ($18-21/user/month extra), Gemini features are included in Workspace plans. This puts Google Chat on par with Slack for AI inclusion, though Slack's AI features are more chat-specific while Gemini spans the entire Workspace suite.
