"Easier and better than I thought and experienced before"

4.5/5

What do you like best about Knock?

I thought Knock is like other services out there. I had the impression that it would not be easy or as simple as that. I will have to do a lot more digging into documentation in order to actually set it up. But turns out it's not difficult. Documentation is great. UI is very friendly. You can find all the topics you need right there and you don't have to wander in the menu items to look for what you need. Integrating it with our application was a piece of cake thanks to the documentation. I was able to test all the flows we have in just a few minutes. Review collected by and hosted on G2.com.

What do you dislike about Knock?

I am not really sure at this moment about that. I will have to use it more to figure out what are the real pain points that I can give feedback for. Review collected by and hosted on G2.com.

"surprisingly simple yet powerful notification platform with an amazing developer experience"

5/5

What do you like best about Knock?

- really straightforward to setup a powerful in-app experience in my webapp

- clearly built with developers in mind

- solid user interface, great logging / debugging tools for understanding when your notifications aren't working

- very thorough documentation

- responsive customer support Review collected by and hosted on G2.com.

What do you dislike about Knock?

- I found some aspects of the git commit workflow a little confusing at times when commits kept piling up, which made it a bit hard to keep track of changes... but this was a super minor annoyance Review collected by and hosted on G2.com.

What problems is Knock solving and how is that benefiting you?

I built an entire in-app notification workflow for various flows in my company's webapp. When users perform certain activities like joining an organization or creating a project, or submit requests, I want to notify specific users of these actions. I found it very straightforward to configure these workflows both in the code and inside the Knock UI. Review collected by and hosted on G2.com.

"Full features, Good Support"

4.5/5

What do you like best about Knock?

Knock is a designed notification service built with developers in mind. It provides all the necessary features required for a notification system, making it easy to integrate and manage notifications across multiple channels. The platform stands out for its flexibility, allowing developers to customize workflows, templates, and delivery preferences with ease. Additionally, Knock’s support is good enough. They offer a Slack workspace for real-time assistance and are highly responsive to emails, ensuring quick resolutions to any issues. Review collected by and hosted on G2.com.

What do you dislike about Knock?

Debugging tools could be more advanced, making it easier to trace and troubleshoot notification flows. For larger teams, more ACL options would be beneficial to better manage permissions. Additionally, occasional minor changes, such as updates to Liquid logic, are made without sufficient awareness, which can cause unexpected issues. Review collected by and hosted on G2.com.

"As a young company, Knock already creates significant value for us as a customer."

4/5

What do you like best about Knock?

- The existing core features work reliably out of the box

- The entire team (that we've interacted with), including customer support, is very open, collaboratively minded and quick to respond

- Initial prototyping is fast and easy, allowing us to get features out of the door quickly

- Integrations with our service and other external services (e.g. June, Mailgun) could not be easier! Review collected by and hosted on G2.com.

What do you dislike about Knock?

- As with any young company, you will encounter use cases or parts of the product that are a bit rough around the edges. However, the team acts quickly on corresponding requests

- The reliance on low-code tooling for designing notification workflows makes it easy to get started, but comes with scaling pains at some point (this is not Knock-specific, any low-code tool runs into this eventually). There are workarounds to deal with this programmatically, but not yet as a polished part of the product.

- The provided Python SDK is bare-bones, e.g. it comes without typing and wrappers for expected errors. We had to build our own representation of Knock typing to remedy this. This might (!) apply to other SDKs as well. Review collected by and hosted on G2.com.

What problems is Knock solving and how is that benefiting you?

Knock is taking loads of engineering effort related to building and maintaining notification infrastructure off our shoulders. Many related parts that are non-trivial to solve (e.g. batching, delaying) work intuitively and reliably out of the box. It allows us to focus mostly on the business impact of notifications, with greatly reduced technical overhead. Review collected by and hosted on G2.com.
