"Great product and great service"
What do you like best about StackOne?

The StackOne product is fantastic. The value it provides is huge in being able to deliver an integration with such ease.

The team are responsive, open, and easy to worth with. When we need help, they're very supportive; when we give feedback, they're willing to receive it and they take action accordingly. Review collected by and hosted on G2.com.

What do you dislike about StackOne?

We find that we often have to go searching for something ourselves rather than it being offered proactively. We would appreciate (and have worked with the team to get this) more direction on this areas which StackOne are such experts in. Review collected by and hosted on G2.com.

StackOne is incredibly easy to deploy and integrate—our engineering team had it up and running in no time. Their team is highly engaged, proactively collaborating with us and even talking directly to our customers to ensure smooth adoption.

What do you dislike about StackOne?

The LMS suite is still in its early days, so the number of supported learning management systems is somewhat limited. I’m confident this will improve as their offering matures. Review collected by and hosted on G2.com.

"Responsive Team and Fast Feature Turnaround"
What do you like best about StackOne?

The standout aspect of StackOne is their excellent customer support. Their team is incredibly responsive and genuinely listens to our feedback. Whenever we’ve requested new functionalities or improvements, they’ve acted on them quickly—often faster than expected. It feels like a real partnership where our needs are prioritized and addressed with care. Review collected by and hosted on G2.com.

What do you dislike about StackOne?

One limitation is the lack of testing or sandbox accounts to try out integrations before going live. It would be helpful to have a safe environment to validate our implementation without impacting production data. This would make onboarding and experimentation much smoother.

"Using and working with stackOne product"
What do you like best about StackOne?

StackOne's product just simplify the entire integration and make thing easier for our team, which is helpful and working with stackOne directly, they are fast to address the issue we raise, they also keep us update with the issue so we know the process. Review collected by and hosted on G2.com.

What do you dislike about StackOne?

The downside that I can think of is stackOne is a unified API, so in a certain time, when there are update, it also breaks some of our function, which delay some of our process but this is quite rare. Review collected by and hosted on G2.com.
