Courier
Multi-channel notification API
Free tier + paidEmail, forms & notificationscourier.com
What it is
Notification API that routes one logical message across email, SMS, push, chat and in-app channels, with automatic fallback when a channel fails or goes unread. Includes a drag-and-drop template designer non-developers can edit, preference management and an inbox component. Connects to your existing providers rather than replacing them.
Why it earns a slot
The template studio means a founder or designer edits notification copy without a deploy. Channel fallback — try push, fall back to email if unopened — is a single toggle here.
Know before you commit
Pure per-send pricing with no bundled volume tiers gets expensive next to Novu at scale. The free tier is generous, but the designer-friendly workflow is what you are really paying for.
Neighbourhood
How Courier sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
