"Easy access for our non-technical team"
The level of visibility Knock provides into our notification system was a game-changer. Our customer service team can now easily access the entire history of a notification, from the initial template to the final delivered message.

"Notifications at scale"
Notification infrastructure is the most essential part of any product that I'd never dare build myself from scratch or operate at scale. Knock's APIs allow me to focus on my front-end experience, while all the complexity is abstracted away.

"Fantastic product, shipped in-app notifications in record time"
We unblocked our marketing and education teams to start pushing in-app notifications in a couple days instead of a month or more. Install the React SDK, customize the CSS, and you're good to go.

"What used to take weeks now takes minutes"
Thanks to Knock's core functionality, our teams are able to easily build complex notification flows (batching, delays, multi-channel notifications, etc). The Knock dashboard is a powerful tool for visualizing notification templates and debugging.

"We collaborate faster with product and marketing"
We wanted to increase our agility and be able to say "yes" more often to product and marketing teams. Knock was exactly what we were looking for. And now we're not wasting our time figuring out infra. We are just able to focus on driving adoption of new features.
VP of Engineering • Webflow
"It's been a great tool and a great team"
Its comprehensive API and clear documentation allowed us to get a proof of concept running within days. The multi-channel support aligned perfectly with our vision for future notification capabilities.

"Knock let us save on costs and focus on opportunities"
I like how transparent the interface is when you send messages through. You can typically see a failure in a workflow execution right from the UI. That makes it really easy to diagnose when something's wrong.
