3 tools · the Catch, not a ranking
- ntfyHTTP pub-sub notifications you can curl from cron
Anonymous topics are passwords — guessable names leak other people's alerts. Public ntfy.sh rate-limits; reserved topics need Pro. Dual license means you pick Apache-2.0 or GPLv2, not Apache-only.
- CentrifugoApache-2.0 Go realtime server binary, not in-process Socket.IO
You run it. This is not Socket.IO in-process. Cloud/PRO SKUs were unverified here — no invented Cloud prices. Ops, clustering, and Redis when you scale stay yours.
- SocketClusterMIT Node pub/sub+RPC+JWT with SCC scale-out
Node pub/sub+RPC+JWT+SCC scale-out — not Socket.IO library-only, not Soketi Pusher-protocol, not Centrifugo Go hub, not NATS messaging, not AnyCable Rails WS. Distinct from Socket.IO, Soketi, Centrifugo, NATS, and AnyCable.
