Mattermost’s pricing structure confuses a lot of buyers. There are three official tiers, a new fourth tier announced in early 2026, two deployment models (self-hosted and cloud), and a per-seat annual billing model that can dramatically change what you actually pay depending on team size. This guide cuts through all of it with exact 2026 figures, a cost calculator for common team sizes, and a clear comparison against Slack and Microsoft Teams.
Mattermost Plans at a Glance — 2026
| Plan | Price (per user/month) | Billing | Deployment | Best For |
|---|---|---|---|---|
| Starter | Free | — | Self-hosted only | Evaluation, small teams, limited budget |
| Professional | $10.00 | Annual prepaid | Self-hosted or Cloud | Growing teams needing SSO, LDAP, compliance basics |
| Enterprise | Custom (contact sales) | Annual prepaid | Self-hosted or Cloud | Large orgs, HA clustering, advanced compliance |
| Enterprise Advanced | Custom (contact sales) | Annual prepaid | Self-hosted (air-gap) | Defense, government, multi-domain secure ops |
Mattermost Professional and Enterprise licenses are sold as prepaid annual subscriptions per activated seat. There is no monthly billing option for official licenses.
Mattermost Professional — $10/User/Month
Professional is the entry-level paid tier at $10 per user per month, billed annually — meaning you pay $120 per user per year upfront. It covers every core feature that Starter lacks for a production deployment:
- Single Sign-On (SSO) — SAML 2.0, OpenID Connect, OAuth 2.0
- AD/LDAP User Sync — automated user provisioning and group sync from Active Directory or OpenLDAP
- Multifactor Authentication (MFA) — TOTP-based 2FA enforcement
- Guest Accounts — external users in restricted channels (single-channel guests are free at a 1:1 ratio with licensed seats)
- Advanced Access Controls — read-only channels, restricted mentions, admin-controlled channel membership
- Custom User Groups — up to 256 users per group for @mention broadcasting
- Group Audio Calling & Screen Share — up to ~50 concurrent users per call, fully self-hosted
- Business Hours Support — 12×5 Pacific Time
- Self-Hosted or Cloud Deployment — your choice
- AI Bot Support & Multi-LLM Integration — connect your own LLMs (Ollama, LocalAI, OpenAI-compatible)
Professional Plan — Annual License Cost by Team Size
| Users | Monthly Cost | Annual License Fee | 3-Year Total (license only) |
|---|---|---|---|
| 10 | $100 | $1,200 | $3,600 |
| 25 | $250 | $3,000 | $9,000 |
| 50 | $500 | $6,000 | $18,000 |
| 100 | $1,000 | $12,000 | $36,000 |
| 250 | $2,500 | $30,000 | $90,000 |
| 500 | $5,000 | $60,000 | $180,000 |
Note: These are license-only costs. Self-hosted deployments add server infrastructure costs (see TCO section below). Cloud deployments include hosting but remove your infrastructure control.
Mattermost Enterprise — Custom Pricing
Enterprise pricing is not published. Mattermost negotiates based on seat count, contract length, and support tier. Based on public market data and reseller experience, typical ranges in 2026 are:
- Small deployments (50–200 seats): $20–$30/user/month
- Mid-market (200–1,000 seats): $15–$25/user/month (volume discount)
- Enterprise (1,000+ seats): $10–$18/user/month (negotiated)
Enterprise adds everything in Professional plus:
- High Availability (HA) Clustering — horizontal scaling across multiple servers, zero-downtime deployments
- Enterprise Search — Elasticsearch/OpenSearch integration for post history beyond 3 million entries
- Automated Compliance Exports — scheduled exports for HIPAA, SOC 2, ISO 27001 audit trails
- Custom Admin Roles — granular permission delegation below the System Admin level
- Custom EMM (AppConfig) — Mobile Device Management integration for locked-down device deployments
- 24×7 Support with 4-Hour Response SLA
- Performance Monitoring Dashboard — Prometheus-compatible metrics
- Advanced Permissions & Channel Moderation
Enterprise Advanced (New in 2026)
Announced in early 2026, Mattermost Enterprise Advanced is a new top tier targeting defense, intelligence, and critical infrastructure organizations. Key additions over standard Enterprise:
- Multi-Domain Federation — secure messaging across classification levels or air-gapped networks
- Cross-Domain Solution (CDS) Support — for environments with data transfer guards between security domains
- Full Air-Gap Deployment — no external dependencies whatsoever; AI features run on private inference
- Enhanced Audit & Forensics — tamper-evident logging for chain-of-custody compliance
Enterprise Advanced pricing is exclusively by direct sales or authorized reseller. Contact @DoCrackMe on Telegram for current reseller pricing.
Mattermost Starter — Free Self-Hosted
Starter is genuinely free and self-hosted with no user limit. It is the right choice for:
- Technical evaluation before purchasing a paid license
- Small internal teams (under 10 people) with no compliance requirements
- Open-source projects and community deployments
Starter does NOT include: SSO, AD/LDAP, MFA enforcement, guest accounts, compliance exports, HA clustering, or any paid support. For a production deployment serving more than a small internal team, Professional is the minimum viable tier.
Self-Hosted vs Cloud — Which Is Cheaper?
Mattermost Professional is available both self-hosted and as a cloud service at the same $10/user/month license price. The difference is in infrastructure cost and data control:
| Self-Hosted | Cloud | |
|---|---|---|
| License cost | $10/user/month | $10/user/month |
| Infrastructure cost | $30–$150/month (VPS, 50 users) | Included |
| Data residency | Your servers, your country | Mattermost-managed AWS |
| Air-gap possible | ✅ Yes | ❌ No |
| IT admin required | Yes (Linux admin) | No |
| Backup control | Full control | Managed by Mattermost |
| Suitable for Iran/restricted regions | ✅ Yes | ❌ Blocked by sanctions |
For most DoCrack customers — teams in Iran, CIS countries, or organizations with data sovereignty requirements — self-hosted is the only viable deployment model. The Mattermost Cloud service requires a payment method and IP address that clears Mattermost’s sanctions screening, which blocks most Iranian organizations.
Total Cost of Ownership (TCO) — Mattermost vs Slack vs Teams
License price alone does not tell the full story. Below is a 3-year TCO comparison for a 50-user team:
| Mattermost Professional (Self-Hosted) | Slack Pro | Microsoft Teams (M365 Business Basic) | |
|---|---|---|---|
| License/subscription (3yr) | $18,000 | ~$18,900 ($10.50/user/mo) | ~$10,800 ($6/user/mo) |
| Infrastructure (3yr) | ~$3,600–$7,200 (VPS) | $0 (SaaS) | $0 (SaaS) |
| Admin overhead | Medium (Linux admin ~2–4h/month) | Low | Low–Medium |
| Data residency control | ✅ Full | ❌ US servers | ❌ Microsoft cloud |
| Works in Iran (self-hosted) | ✅ Yes | ❌ Blocked | ⚠️ Restricted |
| 3-Year Total Estimate | ~$22,000–$25,000 | ~$18,900 | ~$10,800 |
Mattermost’s TCO is higher than Microsoft Teams in raw numbers, but Teams’ actual cost rises significantly when you add Microsoft 365 Business Standard (required for full features) at $12.50/user/month — bringing the 3-year Teams total to ~$22,500, comparable to Mattermost. And Mattermost gives you complete data sovereignty that neither Slack nor Teams can offer.
How Mattermost Licenses Are Sold
Understanding the licensing model prevents common mistakes:
- Seat = Activated User. A seat is any registered, non-deactivated user on a specific Mattermost server. You pay for the number of seats you purchase upfront, not actual monthly active users.
- Annual prepaid only. There is no monthly billing for Professional or Enterprise. You pay for 12 months upfront per seat.
- One license per server. A license file is tied to a specific Mattermost server URL. If you run multiple separate Mattermost instances, each needs its own license.
- Seat deactivation is your friend. If a user leaves your organization, admins can deactivate them in the System Console. Their history and preferences are retained but the seat becomes available for reassignment. You cannot reduce your seat count mid-contract, but you can reassign seats.
- Guest accounts at 1:1 ratio. Single-channel guests (external users restricted to exactly one channel) are free at a 1:1 ratio with licensed seats. A 50-seat license allows up to 50 free single-channel guests.

Frequently Asked Questions
How much does Mattermost cost in 2026?
Mattermost has three tiers in 2026. The Starter plan is free (self-hosted, limited features). The Professional plan costs $10 per user per month ($120/user/year) billed annually. The Enterprise plan is custom-priced — contact Mattermost Sales or an authorized reseller. Enterprise Advanced, a new tier announced in 2026 for multi-domain secure operations, is also available by contacting sales.
What is the difference between Mattermost Professional and Enterprise?
Professional ($10/user/month) covers SSO, AD/LDAP sync, MFA, guest accounts, and business-hours support. Enterprise adds HA clustering, compliance exports, custom admin roles, advanced Elasticsearch search, and a 24×7 support SLA with 4-hour response. Enterprise Advanced (2026) adds multi-domain federation for air-gapped and classified deployments.
Is Mattermost free for self-hosted?
Yes. Mattermost Starter is free and self-hosted with unlimited users, unlimited message history, and basic channels. It lacks SSO, AD/LDAP, compliance tools, and HA clustering — features that require a Professional or Enterprise license.
How are Mattermost licenses sold?
Mattermost Professional and Enterprise licenses are sold as prepaid annual subscriptions per activated user (seat). A seat is any registered, non-deactivated user on a specific Mattermost server. Administrators can deactivate users to free up seats; deactivated users retain their message history.
Can I get a Mattermost Enterprise license outside official channels?
Yes. Authorized resellers like DoCrack supply Mattermost Enterprise licenses for organizations that cannot purchase directly due to payment restrictions, sanctions, or regional limitations. Licenses are genuine, fully activatable, and delivered within 24 hours. Contact via Telegram @DoCrackMe.
What is the total cost of ownership (TCO) for Mattermost vs Slack?
For a 50-user team over 3 years: Mattermost Professional self-hosted costs ~$18,000 in license fees plus ~$3,600–$7,200 in server costs = ~$21,600–$25,200 total. Slack Pro costs ~$18,900 over the same period but without infrastructure control or data sovereignty. For organizations with data residency requirements, Mattermost’s TCO advantage is significant beyond the raw numbers.
