What Developers Say About Apryse PDF — And How Syncfusion Solves It

Developers struggle with slow support, steep learning curves, and complex APIs in Apryse PDF. Syncfusion fixes this with SLA-backed support, clear docs, and a simple, intuitive API.

"There is a learning curve to understanding each add-on, the pricing / cost can get out of hand. Plan your project based on what you need and pre-plan and discuss future ramp up to add more modules.”

— G2 user
Unlike other solutions that demand extensive pre-planning and rely on multiple add-ons, the Syncfusion PDF Library is simple to adopt and packed with all the essential features from the start. With built-in support for form filling, redaction, digital signatures, and more — all under a flat licensing model with no hidden costs, it removes the complexity of future upgrades. This makes it a hassle-free and dependable choice for developers and teams alike.

“We cannot utilize it in our TEST environment without purchasing an additional license.”

— G2 user
Syncfusion licensing model includes unlimited deployments across all your environments, without additional cost. No budget surprises.

“Very expensive for the amount of bugs we find in the software. When raising bugs with their support team, responses are extremely slow and have to be constantly chased for an update. There is also no way to get a consolidated view of support tickets raised by different team members, meaning invidividual tickets have to be chased by the individual who raised them. We've had outstanding issues for months and even escalating to an account manager does not deliver a quick response to get a resolution. Our whole team are very downbeat about our experience using this software. Would not recommend, we have been very disappointed with the level of service.”

— G2 user
At Syncfusion, we provide SLA-backed support with guaranteed response times, team ticket visibility for consolidated tracking, and transparent communication throughout resolution. Our proven support system ensures issues are addressed promptly with clear escalation paths and dedicated account management.

What Our Customers Say

Real feedback from developers who rely on Syncfusion every day.

“We are migrating right now from pdftron to syncfusion as it does a much better job, has better documentation and it's cheaper than pdftron. The support is also the best we have encountered so far. A reported bug was fixed and deployed within a few days.”

“I had one difficulty with the PDF generator and reached out to the support team, they worked hard to understand my specific implementation (hosting environment) and they were able to un-stick me. Amazing!”
