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
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
64 languages supported — better global team support than Slack (30+) or Teams (40+)
Discord is free team chat that some dev teams adopt — but you should probably not. The product is genuinely good and free forever for core functionality, but lacks enterprise features (SSO, compliance, admin controls, data retention policies) that any real business needs. Discord makes sense for public communities, gaming, or pre-revenue hobby projects. It's a liability for anything compliance-adjacent.
