Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Ergo
- IRC protocol only; no voice, video, reactions, or rich embeds expected by modern chat users.
- No web client included; users need a separate IRC client (WeeChat, HexChat, etc.) or an IRC-to-web bridge.
- Message history is limited and not searchable at scale compared to Slack's enterprise search.
- No integrations with productivity tools (calendars, task managers, CI/CD) without external bridges.
Rocket.Chat
- Resource-heavy (Node.js + MongoDB) and can be slow at scale on modest hardware
- Some enterprise features (engagement dashboard, scalability, advanced auth) require a paid plan
- UI can feel cluttered compared to Slack
- Mobile apps have historically lagged the web client in polish
Bottom line
Both are a similar lift to self-host; choose Rocket.Chat for the larger community and ecosystem. Rocket.Chat has seen more recent development. Open each guide below for deploy steps and the full feature gap.
