(5 reviews) ## Knock Reviews ### 1. It works decently out of the box, but I find the data model confusing. **Rating:** 2.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** September 16, 2025 **What do you like best about Knock?** It's easy to get started and start sending notifications **What do you dislike about Knock?** I found the data model with tenants/objects/collections confusing. Also whenever I am in the knock app looking for errors/logs it's hard to find what I am looking for. **What problems is Knock solving and how is that benefiting you?** We wanted to send slack notifications to our users and it helped me set that up quickly **Official Response from Sam Seely:** > Thanks for your feedback! Can you share some additional context about your use case and where you found our data model confusing? I'm at sam @ knock.app if easier to connect over email, or can do a call to discuss in more detail. Also if there was anything in particular you were looking for in logs that you had a hard time finding please let us know—we're always pushing to uplevel that experience so any additional detail is a big help! ### 2. Knock is an excellent upcoming multi-channel notification service **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** August 02, 2023 **What do you like best about Knock?** Knock makes it absolutely trivial to achieve multi-channel notification support in your app. It supports emails, SMS, Slack, and everything else any reasonable app could ask for. It makes delegating copy and design to others easy through the online template editor. **What do you dislike about Knock?** Knock has some issues, particularly with bugs and production readiness. They have a sub-par Golang client that makes heavy use of untyped data, and their payload format doesn't support strong typing. Knock has no clean way to manage payload specs in git, despite having environment support. Their environment system lacks branching capabilities, meaning many developers must share the development environment which can sometimes cause issues. The commit system is a good idea, but lacks the info required to be truly useful. It doesn't show the author of a commit or what was changed. **What problems is Knock solving and how is that benefiting you?** Knock solved our problems with having multiple vendor implementations maintained by us lying around in our repository. These would frequently become out of sync and our codebase had no easy way to have multi-channel workflows. - [View Knock pricing details and edition comparison](https://www.g2.com/products/knock-knock/reviews?filters%5Bnps_score%5D%5B%5D=3§ion=pricing&secure%5Bexpires_at%5D=2026-08-13+19%3A45%3A32+-0500&secure%5Bsession_id%5D=80aee637-5aab-4fa5-addc-e8042b93221e&secure%5Btoken%5D=1780e61f67b6729b2afdf7e70692a9d9e46b945a6acd7c30c7a796f588b8caaf&format=llm_user) ## Knock Integrations -
