Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
ntfy
- No team chat, threading, or message history browsing; designed for one-way push alerts only.
- No rich message formatting, file sharing, or reactions.
- Rate limiting and attachment storage on the free public server are intentionally restrictive.
- iOS push requires routing through ntfy's own APNs proxy unless you self-compile the app.
The Lounge
- It is an IRC client, so you still need IRC servers/networks for actual chat
- IRC lacks native threads, rich file sharing, and message editing that Slack offers
- No built-in voice/video or app integrations
- Persistence and history depend on a connected bouncer/IRC setup
Bottom line
Both are a similar lift to self-host; choose ntfy for the larger community and ecosystem. ntfy has seen more recent development. Open each guide below for deploy steps and the full feature gap.
