Overview
Knock is a developer-first notification platform that centralizes multi-channel notifications, workflows, templates, and user preferences behind an API.
Pros
- Developer-friendly API and SDKs
- Supports multiple notification channels
- Good workflow and template management
- Built-in user preferences and feeds
- Fast to integrate for product teams
Cons
- SaaS-only model
- Pricing can grow with volume
- Advanced workflows require setup

Verdict
Knock does a strong job of simplifying notification delivery for developers with APIs, workflows, and multi-channel support. It is best for product teams building in-app, email, SMS, or push notifications at scale. The main trade-off is that it is a proprietary SaaS, so teams needing self-hosting or very low-cost options may prefer alternatives.
