Mattermost vs Wire

Mattermost

• Organizations that must keep chat on their own servers or air-gapped networks
• DevOps and security teams that run incident response from chat
• Small technical teams comfortable hosting their own server

Wire

• Organizations that need end-to-end encryption for messages, calls and files
• Governments and regulated sectors that require on-premises deployment
• Teams that bring outside partners in as guests or externals
• NGOs, which are offered a 40% discount

Mattermost

• No prices are published: Professional, Enterprise and Enterprise Advanced are quoted by sales and sold as prepaid annual seat subscriptions.
• Entry shows only the latest 10,000 channel messages and has community support only; the vendor suggests it for teams of fewer than 50 users.
• It is self-hosted by design; the only vendor-hosted option described is single-tenant Mattermost Cloud Enterprise, arranged through sales.
• Team Edition has no single sign-on, and the vendor does not recommend it for government or sensitive commercial workloads.

Wire

• Prices are listed in euros only.
• Wire for Free stops at 5 team members and cannot start a conference call with more than 2 participants.
• The SMB plan covers teams of up to 100 people; larger organizations need a custom Enterprise quote.
• The Linux desktop app is a community-supported experimental build, and browser calling works only in Chrome.
