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.
SimpleX Chat
- No web client; primarily mobile-focused with a desktop CLI and early-stage desktop app.
- Self-hosting the SMP server requires manual Haskell build or Docker and knowledge of relay configuration.
- No workspace/org structure, channels, or administrative tooling suitable for business teams.
- Integrations and bots ecosystem is minimal compared to Slack or Discord.
Bottom line
Choose ntfy if you want the lower-effort setup; choose ntfy for the larger community and ecosystem. SimpleX Chat has seen more recent development. Open each guide below for deploy steps and the full feature gap.
