Overview

Courier and Knock are direct competitors in notification infrastructure. Both orchestrate multi-channel notifications through provider integrations. The differences are in focus areas — Knock excels at in-app UX, Courier at provider breadth. For our take on each, see our Courier comparison.

Knock's In-app Advantage

Knock's pre-built React components for notification feeds, toasts, and banners are production-ready. Customize the look, handle real-time updates, manage read/unread state. Courier has components too, but Knock's are more polished and comprehensive.

Courier's Provider Breadth

Courier integrates with 50+ delivery providers across channels. More options mean more flexibility in building your notification stack. If you have specific provider requirements, Courier is more likely to support them out of the box.

The Sequenzy Alternative

For SaaS founders who need email specifically (not notification infrastructure), Sequenzy combines transactional email and marketing campaigns with Stripe integration at $49/month — simpler and cheaper than either notification platform.
