I enjoy using Knock. It's a great tool. What I've liked the most is the customer service. The level of service they've provided has been incredible. I'm able to reach out to them via Slack and get a response almost immediately from an actual human that has always been able to help me solve my problems.

Knock is an engineering-first platform. Their API is robust, and they ship solid features at a steady pace.

I think the best feature of Knock is the observability. It allows us to drill down into the specifics of each notification for each user or channel. This level of detail is really, really useful especially when something goes wrong or a user reports not receiving notifications. Our support team can leverage this feature and solve issues pretty easily without the engineers having to dig deep into it. Overall, I also find the documentation, UI, and dashboard to be great, and the support we have received is excellent.
