description:
'''Not recommended.''' Cloud-based team messaging platform with channels,
threads, and integrations. Free tier limits message history to 90 days and caps
integrations at 10. Included here for comparison against [[Mattermost]] and
[[Rocket.Chat]], the two self-hosted alternatives we do recommend. (1) ·
End-to-end encrypted 1:1 and group messaging, plus voice/video calls, built on
the audited Signal Protocol (Double Ratchet + X3DH). ~40M monthly users. Registration
requires a phone number; usernames (added 2024) let you start chats without sharing it. (1) ·
End-to-end encrypted chat on the Matrix open standard. Anyone can run a homeserver
and servers federate like email; Element is the reference client. 115M+ addressable accounts,
with bridges to Signal, Telegram, WhatsApp and others. (1) ·
MIT-licensed, self-hostable team chat with channels, voice/video, and broad
integration support. Its omnichannel inbox unifies live chat, email, WhatsApp, and
Telegram into one agent queue -- useful if you also want to replace a separate
customer-support tool, not just internal chat. (1) ·
Self-hostable, MIT-licensed team chat closely modeled on Slack's channel-based
UX -- includes a Slack export/import path to ease migration. Free self-hosted tier
runs indefinitely with no per-seat licensing cost; paid tiers add SSO, compliance
exports, and HIPAA/FedRAMP-aligned deployment options. (1)
usage notes:
None (3) ·
Fewer native integrations than Slack out of the box -- most third-party
connections go through incoming/outgoing webhooks rather than a marketplace, so budget
some setup time. Good fit for teams that want a near drop-in Slack replacement and
value Go-based, ops-friendly self-hosting. (1) ·
Has the most GitHub momentum of the self-hosted Slack alternatives
(~45k stars). The free Community edition covers most day-to-day needs; exceeding
Starter-plan limits blocks adding new users but does not lock you out of existing
data. (1)
rejected alternatives:
None (3) ·
Relying on the public matrix.org homeserver reintroduces an
operator/jurisdiction -- self-host to get the benefit. Discord and Slack are centralized and
not end-to-end encrypted. (1) ·
WhatsApp (uses the Signal protocol but is Meta-owned and harvests
metadata) and Telegram (chats are not end-to-end encrypted by default, weaker crypto). (1)
