Slack is the category leader for team chat and the tool most product-led companies default to. Pro at $8.75/user/mo annual is the real entry — Free tier's 90-day message history limit makes it unsuitable for any team that relies on chat archives. Third-party app ecosystem (2,600+ apps) is the strongest differentiator vs Teams.
UX is genuinely better than Teams — search, threads, formatting all more refined
2,600+ app integrations — largest ecosystem in team chat
Workflow Builder automates internal processes without code — unique at this price
Microsoft Teams Essentials at $4/user/mo annual is the cheapest serious team chat option by a wide margin — Slack Pro ($8.75) is 2.2x the price for similar core capability. If you don't need Slack's third-party app ecosystem, Teams delivers 90% of the value at half the cost. For organizations already on Microsoft 365, Teams is included — no separate bill.

Mattermost is the Slack alternative for defense, government, and regulated industries. FIPS 140-3 hardened, STIG images, air-gapped deployment, sovereign AI — feature set designed for US federal compliance requirements. Pricing is opaque (contact sales only) but reflects the enterprise-security positioning.
FIPS 140-3 hardened + STIG images — US government compliance out of the box
Rocket.Chat is the self-hostable Slack alternative for teams with data sovereignty requirements. Starter at free-forever for up to 50 users includes full enterprise features (SSO, E2E encryption, RBAC, 64 languages). For compliance-regulated industries, governments, or privacy-maximalist organizations, Rocket.Chat self-hosted is a legitimate Slack replacement at near-zero cost.
Self-hostable for free up to 50 users — includes enterprise SSO, E2E encryption, RBAC
Data sovereignty guarantee when self-hosted — your server, your data, legally defensible
