In early 2026, Slack quietly raised its Pro plan price from $8.75 to $12.50 per user per month — a 43% increase that appeared in billing cycles without much fanfare. Combined with an earlier reduction of the free plan's searchable message history, Slack has given a lot of teams reason to reconsider their subscription.
The question isn't whether Slack is good — it clearly is. The question is whether it's $12.50-per-user good when Microsoft Teams is free with Microsoft 365, Google Chat is free with Workspace, and Discord works fine for small teams.
Slack Pricing Plans in 2026
| Plan | Price | Key Features |
|---|---|---|
| Free | $0 | 90-day message history, 10 integrations, 1:1 video calls |
| Pro | $8.75/user/mo | Unlimited history, unlimited integrations, group video, Slack AI |
| Business+ | $22.50/user/mo | SAML SSO, 99.99% SLA, data exports, 24/7 support |
| Enterprise Grid | Custom | Multi-org, compliance exports, enterprise key management |
All prices are per user, billed annually. Monthly billing adds roughly 18-20%.
The Free Plan: What Changed
Slack's free plan hasn't been fully free for years, but recent changes have made the limits more noticeable:
Message history: The free plan shows 90 days of message history. Before 2023, it was 10,000 messages (which lasted longer for small teams). Now it's strictly time-based — conversations older than 90 days are invisible unless you upgrade.
App integrations: Only 10 third-party integrations. If you're connecting Slack to GitHub, Jira, Google Calendar, and a few others, you'll hit this limit fast.
Video calls: 1:1 video only. No group video meetings on free — a real limitation for remote teams.
Storage: 5GB total. Generous for messages, not for teams sharing files regularly.
For teams of 2-5 that primarily use Slack for text communication and don't need message history beyond 90 days, the free plan remains functional. Beyond that, the gaps are real.
Pro ($8.75/user/mo): What You Actually Get
The Pro plan removes the limits that matter most:
Unlimited message history and search. This is the most common reason teams upgrade. Once a team relies on Slack as institutional memory, losing history is painful.
Unlimited integrations. Connect everything: GitHub, Jira, Salesforce, Zoom, PagerDuty, Linear, and thousands more via Zapier or the native app directory.
Group video and screen sharing. Up to 15 participants per call. Adequate for most team meetings, though not a replacement for Zoom or Google Meet for large company-wide calls.
Slack AI (included in Pro as of 2026). AI-powered search, thread summaries, and daily recaps. The thread summaries are genuinely useful for long async conversations.
Workflow Builder. Automate onboarding, approvals, and notifications without code. Useful but has a steeper learning curve than Zapier.
Guest accounts. Unlimited single-channel guests, useful for working with external clients or contractors.
Business+ ($22.50/user/mo): For Compliance-Heavy Teams
Business+ adds features that most teams don't need until they're mid-market or enterprise:
- ▸SAML SSO and SCIM provisioning for centralized identity management
- ▸99.99% uptime SLA (vs 99.9% on Pro)
- ▸Data exports for all messages (compliance requirement for financial services, legal, healthcare)
- ▸24/7 support with 4-hour response time
- ▸Advanced identity management with two-factor enforcement
At $22.50/user, Business+ is harder to justify unless compliance is a regulatory requirement. Most teams that need SSO but not compliance exports should look at third-party SSO providers or consider whether Teams or Google Chat (included in Microsoft 365 or Google Workspace) covers the need.
The Real Comparison: Slack vs Alternatives
Slack vs Microsoft Teams
Microsoft Teams is included free with Microsoft 365 Business Basic at $6/user/mo, which also includes Exchange email, SharePoint, and OneDrive. If your company already pays for Microsoft 365, Teams costs you nothing incremental.
Teams has caught up in UX. The channel experience is similar to Slack. Video calls are better than Slack's. The main thing Teams still lacks: Slack's integrations ecosystem and developer-friendliness.
Verdict: If you're a Microsoft shop, Teams is the obvious choice. If you're not, the integration ecosystem gap still favors Slack.
Slack vs Google Chat
Google Chat is included with Google Workspace Business Starter at $6/user/mo, again, you're paying for the whole suite, not just chat. Chat has improved in recent years with Spaces (channels), inline message threading, and better search.
Google Chat's weakness is integrations outside the Google ecosystem. If your stack is Google-heavy (Docs, Sheets, Drive, Meet), Chat is a legitimate Slack replacement. If you use a mix of tools, Slack's app directory is substantially better.
Verdict: Google Workspace users should strongly consider Chat before paying for Slack Pro.
Slack vs Discord
Discord is free. For small teams (under 10) doing primarily async text communication, Discord's free tier has no message history limit, unlimited voice channels, and a surprisingly good UX. Many engineering teams at startups use Discord successfully.
Discord's weaknesses for business: no formal integrations ecosystem (Zapier support is limited), voice-heavy design that doesn't match office culture, and no compliance features. Also, explaining Discord to a CFO when you're asking about SOC 2 compliance is an uphill battle.
Verdict: Discord works for small technical teams. It doesn't scale to business needs well.
Is Slack Pro Worth the Price?
The 43% increase from $8.75 to $12.50 is hard to justify on features alone. The main additions since the last price were Slack AI (included in Pro) and Huddles (lightweight audio/video calls). Neither is transformative.
The honest answer is that Slack is raising prices because it can, network effects are strong, switching costs are real, and enterprise customers are sticky. The question is whether your team is at the price-sensitive end or the enterprise-sticky end.
Who Should Pay for Slack Pro
Slack Pro at $8.75/user is worth paying for if:
- ▸Your team has more than 10 people and relies on search across message history
- ▸You have a large integrations stack, more than 10 connected apps
- ▸You're developer-focused and rely on GitHub, PagerDuty, or CI/CD integrations that don't work as well on Teams or Chat
- ▸You have external clients or contractors who need single-channel guest access
- ▸Your team is already deeply embedded in Slack workflows, the switching cost is real
Who Should Reconsider
Slack Pro is harder to justify if:
- ▸You're a Microsoft 365 or Google Workspace shop and Teams or Chat is already paid for
- ▸Your team is under 10 people and stays within 90-day message history
- ▸You're paying for Slack + Zoom + a project management tool, the budget pressure from multiple SaaS subscriptions is real
- ▸Your primary use is async text and you don't need the integrations ecosystem
For Personal Use and Small Communities
Slack has crept beyond offices into hobby groups, open source projects, alumni networks, and friend groups.
Discord is almost always better for personal communities. Free voice channels, unlimited message history, better mobile experience for casual use, and no per-seat pricing. If you are starting a community that is not work-related, use Discord.
Free Slack works for small groups but the 90-day message limit hurts. Your group chat history disappears after 90 days. For a casual friend group, that might not matter. For an open source project or study group where people search old conversations, it is a dealbreaker.
Do not pay for Slack Pro for personal use. At $8.75/user/month, even a 10-person community costs over $1,000/year. That money buys a lot of pizza for in-person meetups. Use Discord, a group chat, or a free forum instead.
Bottom Line
Slack is still the best dedicated team communication tool. The integrations, the developer experience, and the sheer network effect of having every SaaS product integrate with it first are real advantages.
But at $12.50/user, a 10-person team pays $1,500/year for Pro. That's meaningful money. Before renewing, run the math on whether Teams or Google Chat, likely already in your stack, covers 80% of the use case for $0 incremental.
For small teams under 10 who can live within the free plan's 90-day history, stay free and invest the savings elsewhere. For teams with heavy integrations and cross-functional workflows, Pro remains the best option in its category, just not as obvious a value as it was at $8.75.
