- KnockHosted notification workflows; Developer free to 10k messages/mo
Closed-source SaaS — not Novu MIT self-host. LOUD: Starter jumps to $250/mo (50k messages). Downstream SendGrid/Twilio/etc still bill you. HIPAA/SAML/SCIM are Enterprise. Free path is Developer tier only.

Closed SaaS. LOUD (2026): Free mobile push/in-app limited to 1,000 MAU (new orgs Sep 1, existing Oct 1) — overage pauses mobile until Growth (from about $19/mo + per-MAU). Not Novu/Knock twins. SMS/RCS extra.
- MagicBellMultichannel notification API + inbox; Builder free to 1k deliveries/mo
Closed SaaS — not Novu self-host. LOUD: Startup jumps to $249/mo (50k deliveries; $0.0025 overage). Multi-channel = multi-delivery counts. You still pay SendGrid/Twilio/FCM underneath. Not Knock twin for complex workflow DAGs.
