Three platforms dominate workplace and community chat in 2026: Slack, Microsoft Teams, and Discord. Each has a free tier, paid plans, and a surprisingly different pricing philosophy. This comparison cuts through the marketing to show exactly what you pay, what you get, and which platform makes financial sense for your team size.
Quick Verdict by Team Type
Startups (under 20 people): Slack Free or Discord — both give you enough to operate without paying.
Mid-size business (20–200 people): Microsoft Teams if you already pay for Microsoft 365; Slack Pro if you don’t.
Enterprise (200+ people): Teams wins on per-seat cost and compliance tooling.
Communities and gaming: Discord, no competition.

Free Tier Comparison: What You Actually Get
| Feature | Slack Free | Teams (Free) | Discord Free |
|---|---|---|---|
| Message history | 90 days | Unlimited | Unlimited |
| File storage | 5GB total | 5GB total | 500MB per upload |
| App integrations | 10 apps | Limited | Discord bots (unlimited) |
| Video calls | 1:1 only | Up to 100 people | Up to 25 people |
| Audio channels | No | No | Yes, always-on |
| Guest access | No | Yes | Yes (by server invite) |
| Search | Last 90 days only | Full | Full (no time limit) |
The biggest gotcha on free tiers: Slack’s 90-day message history cutoff is brutal for teams that reference past decisions. You lose institutional knowledge after three months unless you pay. Teams and Discord both give you unlimited history at no cost, which is a significant free-tier advantage.
Real Cost at Scale: 10, 50, 200, and 1,000 Users
Per-seat pricing looks tidy on a pricing page. It looks different when you multiply it across a growing team.
Annual Cost Comparison Table
| Team Size | Slack Pro | Teams Business Basic | Discord Nitro (per user) |
|---|---|---|---|
| 10 users | $870/yr | $720/yr | $1,199/yr |
| 50 users | $4,350/yr | $3,600/yr | $5,994/yr |
| 200 users | $17,400/yr | $14,400/yr | $23,976/yr |
| 1,000 users | $87,000/yr | $72,000/yr | $119,880/yr |
A few things to note here. The Teams number ($6/user/month) includes Exchange email, SharePoint, and web Office apps — so it’s not purely a chat cost. If you’re replacing a separate email provider, that $6 rate is genuinely cheap. Slack at $7.25 is chat only; you’d stack email costs on top.
Discord Nitro per-user cost looks high because Nitro is an optional individual subscription, not a team license. Most Discord servers operate without requiring every member to have Nitro. The server itself may be boosted (which costs money), but members don’t need paid accounts to participate fully in text and voice.
Hidden Costs Nobody Talks About
Slack
- Slack Connect seats: External collaboration channels count toward your billing when the external user joins your workspace under certain plan configurations.
- Storage overages: Files stay within plan limits. Large teams sharing media regularly hit storage caps faster than expected.
- Workflow automations: Advanced automation features (Workflow Builder on Business+) add complexity at the higher tier — pushing teams up a plan earlier than anticipated.
Microsoft Teams
- Phone System add-on: Calling Plans for PSTN calling start at $8/user/month on top of your base plan. Many businesses don’t realize this isn’t included by default.
- Advanced compliance add-ons: Full eDiscovery, Communication Compliance, and Insider Risk Management require Microsoft 365 E5 or add-on licenses. E5 runs $57/user/month.
- Teams Rooms hardware: Conference room setups require certified hardware and a Teams Rooms license ($40–$50/device/month for Pro). A mid-size office with five meeting rooms adds $2,400–$3,000/year just for room licenses.
Discord
- Server boosts: Server perks are unlocked by boosts, not by admin accounts. Getting to Level 3 (the best tier) requires 14 boosts. At $4.99/boost/month, that’s $69.86/month ongoing — or $839/year — just for server-level features like better audio quality and larger file uploads.
- No business invoicing: Discord has no official invoicing, group billing, or enterprise procurement. Teams using Discord professionally buy Nitro individually and expense it, creating accounting friction.
Video and Audio: Where Each Platform Stands
| Feature | Slack | Microsoft Teams | Discord |
|---|---|---|---|
| Max video meeting size (paid) | 50 people | 1,000 people | 25 people (stage: 1,000 view-only) |
| Meeting recordings | Yes (Business+) | Yes (all paid tiers) | No native recording |
| Meeting transcripts | Paid tiers | Yes (with Copilot add-on for AI) | No |
| Always-on voice channels | No | No | Yes (a Discord signature feature) |
| Screen sharing | Yes | Yes | Yes (Nitro for 4K) |
| Background blur/replace | Limited | Yes | No |
| Webinar/event hosting | No | Yes (Business Standard+) | Stage Channels (free) |
Teams is the clear winner for formal video meetings — especially for external client calls, webinars, or large all-hands events. Discord’s Stage Channels are a compelling free alternative for community events and announcements, but lack professional polish. Slack’s video is functional for internal standups but trails both competitors for large-format calls.
Integrations and App Marketplaces
Slack
Slack’s app directory has over 2,600 integrations including deep connections to GitHub, Jira, Salesforce, Zendesk, PagerDuty, and Google Workspace. The free tier caps you at 10 active integrations — a real limitation for teams running more than a handful of tools. Paid tiers remove the cap. Slack’s API is developer-friendly and webhook-based automation is mature.
Microsoft Teams
Teams integrates tightly with the entire Microsoft stack (SharePoint, OneDrive, Planner, Power Automate, Dynamics 365) and has 800+ third-party apps in the Teams App Store. If your business runs on Microsoft products, the integration depth is unmatched. Power Automate provides no-code workflow automation that goes well beyond what Slack’s Workflow Builder offers at comparable price points.
Discord
Discord’s bot library is massive but informal. Thousands of community-built bots handle moderation, music, games, polls, reaction roles, and analytics. There’s no official business app marketplace. For professional tool integrations (Jira, Salesforce, etc.), you’ll rely on third-party bots or Zapier/Make. This works for tech-forward teams comfortable with self-hosting bots, but it’s not a turnkey enterprise solution.
Search and Compliance
This is where Microsoft Teams pulls significantly ahead of both competitors for regulated industries.
- Slack: Full message search on Pro+. Data exports require Business+ or Enterprise Grid. HIPAA compliance available on Enterprise Grid only. eDiscovery requires Enterprise Grid with additional configuration.
- Teams: Full search across all paid plans. Native integration with Microsoft Purview (formerly Compliance Manager) for HIPAA, GDPR, FedRAMP, and SOC 2. eDiscovery, legal holds, and retention policies built into M365 E3 and above.
- Discord: Basic message search with no enterprise compliance tooling. Not suitable for industries with regulatory data retention requirements (financial services, healthcare, legal). Server audit logs exist but are minimal.
If your team operates under HIPAA, SOX, FedRAMP, or similar requirements, Teams is essentially the only choice of these three without significant third-party add-ons.
Who Should Use What
Use Slack if:
- You run a non-Microsoft stack (Google Workspace, AWS, GitHub-centric workflows)
- Your team treats integrations as core to how work gets done
- You want best-in-class developer and product team UX
- You’re willing to pay more per seat for a cleaner, more focused chat experience
Use Microsoft Teams if:
- You already pay for Microsoft 365 (Teams is essentially free at that point)
- You’re in a regulated industry needing compliance features
- You run large-format internal meetings or client webinars regularly
- You want phone/PSTN calling integrated into your communication stack
Use Discord if:
- You’re building or managing a community (gaming, content creators, open-source projects)
- Your team is small and informal, comfortable with a less structured environment
- You want always-on voice channels for spontaneous collaboration
- You don’t need formal invoicing, compliance, or enterprise procurement
The Bottom Line on 2026 Pricing
Best value overall: Microsoft 365 Business Basic at $6/user/month — you’re getting email, storage, and Teams together. It’s hard to beat on pure cost-per-feature.
Best UX for product/dev teams: Slack Pro at $7.25/user/month. The integration depth and developer-friendly experience justify the premium over Teams for non-Microsoft shops.
Best free tier for a business: Teams Free or Discord — both give unlimited message history and solid video without a credit card.
Don’t pay for Discord Nitro per-user for business use. It’s designed for individuals, not teams. If you’re running a professional Discord server, budget for server boosts instead.
