What you give up vs Slack

  • 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.

What you gain

  • • Full data ownership — self-host ntfy on your own infrastructure.
  • • No per-seat SaaS bill (Slack: per-seat pricing and a capped message history).
  • • Open-source code you can audit and extend (Apache-2.0).
