Flexible content workflows have transformed how our team updates seasonal messaging in real time

Overall, we have used Contentstack to great effect as our headless CMS.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We achieved specific outcomes from using Azul Zulu by reducing our Java licensing and support costs by approximately 70% when compared to our previous Oracle contract."

"We've had no issues with stability."

"The speed index has had a great impact; earlier we had something in the 60s on Google Page Insights, but now we are able to achieve 90-plus."

"Contentstack has positively impacted our organization, as tracking changes made by our very large team is difficult, so we are using Contentstack to update data in real-time."

"Contentstack is a great tool; the service helped us stay on track with our headless launch and deliver on time, and we are beyond happy with the service provided and still being provided."

"Contentstack has saved time and improved efficiency, and compared to other products, it is cost-effective and not expensive."

"The ease of use, which I mentioned as the best part, is especially highlighted by the clean UI and predictable UX of Contentstack, as there is not too much information on the screen at the same time that can confuse the users."

"Contentstack has created an impact of quick access to a non-tech person to add the properties right away and to work on their own personalized marketing campaigns and other aspects."

"Contentstack has impacted my organization positively by helping us to deliver an application with a very good quality in terms of how it looks and feels."

Cons

"Improvements for Azul Zulu could include more automated tools for unused code visibility integrated directly into the standard portal to help further optimize our cloud footprints."

"It needs a better update daemon. At this time the process is manual and could be an issue on multiple desktop deployments."

"Contentstack is much more complex and advanced technology. I think there are still some UI improvements which can be done to simplify the work."

"For improvement, I want to clear the cache for the pages, as Contentstack does not provide a default way of invalidating the cache."

"I noticed that sometimes it takes time, and I am not sure about the server side, as it may not be responding."

"The API, specifically the Content Delivery API, can be a bit tricky sometimes."

"It is good, but not great. For something like eighty percent of my set of tasks, I can scale based on the background we have with Contentstack."

"We are more worried about the pricing. For example, somebody who is a tech person trying to integrate based on the events finds it a little bit more not so accessible."
