Zendesk has been instrumental in building our Knowledge Center. It's easy to set up, intuitive to navigate, and managing content is a breeze. But here's the catch: it's not cheap. Sure, it offers top-notch features and a seamless user experience, but the cost can be a hurdle, especially for smaller businesses. If you're ready to invest in quality, Zendesk is the way to go. Four stars because, well, premium features come with a premium price.
