We Love to Hear Dev's Opinions on Reddit
If we can impress Reddit developers, we can impress anyone.

Aspose had us buy paid support (expensive) to get action on a bug because the free support went nowhere.
IronPDF
Iron has no limits on support tickets. Join the hunt with our Bug Bounty Program and let us turn those problems into better products.
The other thing is the cost of Aspose.PDF...it is a big risk to pay out so much to start.
IronPDF
IronPDF production licensing starts at $999.
I can see on the Aspose forums that there are tickets open to address this but, as of now, there is no ETA for the delivery of the libraries for .NET Core.
IronPDF
Nothing gets left behind by Iron Software’s support team. In 2023, they answered 26,447 tickets, more than 70 a day.
I purchased Aspose Total.NET for its features but found the documentation utterly diabolical, offering no clear guidance on which components to use for basic tasks.
IronPDF
Iron Software has clear, comprehensive, and maintained documentation.
Aspose sales response time was pretty disappointing. At times I needed to wait more than 1-2 days for a reply.
IronPDF
IronPDF 24/5 Live Chat support promises a 24-hour SLA. And we have a public Slack channel which puts you in direct contact with our software engineers.
