Nutrient SDK

Pros: Quick support provided by Omar Talaat and noe it's working perfectly.
Many many thanks Omar for currently it's smoothly working for all config.

Cons: Nothing and keep it same kind of support :) and your support are very important for us to rectify this issue.

Overall: It was great experience and support much happy than expected.
PSPDFKit is very useful library for front end.

Pros: Good application with a great support team. The product is stable without many error, bugs or downtime. The support team is one of the friendliest I have experienced. They also keep PSPDFKit updated with the newest technologies.

Cons: I somewhat miss documentation. The ticket I had about implementing annotations could've been avoided by having more community supported articles and more defining documentation. Don't get me wrong, they already have quite the documentation. But the solution that I was looking for wasn't found without a dev on their side.

Overall: Working with the people from PSPDFKit was a good experience. They are friendly and mean to help. They have a good product which gets updated often.

Pros: It is very easy to use. Everything you need can be easily found in the documentation. Also the support team is very responsive and always happy to help with any problems.

Cons: Sometimes it can have limited functionality and limited customization.

Overall: I would recommend. I had a great experience working PSPDFKit. They provided workarounds when something was not 100% doable.

Pros: Great and easy to follow API, helpful guides and examples.

I mostly deal with server side and had no problems with deploying it all on premises. I found their app/browser-based editing/working with PDF examples much much much better. Demos are top-notch and give you immediate picture of what you can do.

Cons: Licensing seemed a bit confusing to me which is understandable for such a suite, but it's drastically improving now that they are consolidating their products into Document Engine, etc.

Overall: PSPDFKit is fanatical about handling PDF. I first heard about them over a decade ago as an ios pdf renderer library, and when I needed a solution to work with PDFs, I immediately remembered them, discovering they'd created a whole suite of products since then to work with PDF.

At my company, we build accounting software and we've adopted their product for generating PDFs.

I've always considered PDF as a frightening nebulous proprietary standard that has no proper cross-platform tooling, so I gladly settled for mediocre exports of documents with botched layouts and fonts, but not anymore. We can now create PDF documents exactly the way we want them to look like.

As a customer, I'm hopeful for a long productive partnership.

Pros: PSPDFKit team, quickly, qualitatively and excellently helped with various questions related to document caching on iOS and Windows platforms.

Cons: We couldn't find any cons, since the PSPDFKit team did their job well.

Overall: Many thanks to PSPDFKit team for their assistance in various questions mentioned above.
This helped save time on finding a solution to the problem and achieve the desired result.

Pros: Fast, complete and pointing to the right solution.

Cons: This time none :-)

Overall: Whenever I needed assistance, I got it. In Time!

Pros: - UI and UX look clean and friendly.
- Execution fast enough considering number of features.
- Most complete web PDF features on market

Cons: - With only base features of PDF viewer, its already pricy. Should have been lower price so it will be much easier for small companies developer folks to convince their upper management for budget approval. Or include all features such as annotation and redact.
- Have not try all but per documentation, there are not enough types of event. When I need to know when the viewing document is printed or downloaded I must use custom toolbar button.
- File *.wasm is still large size after compression so initial static content caching is slow.

Overall: There is not much choice in the field for PDF viewer and redaction. This is the best one. There are some free open sources being contributed but they are not very stable or not enough features.

Pros: The product is very customizable and can be integrated with other custom applications.
Support is very quick to reply to questions and provide answers.

Cons: It requires a large number of files to be included and published at a location within the context of the app. In my case this was a SharePoint app and the toolchain for app creation does not handle this scenario well so we had to manage deployment of these files separately.

Overall: Great product, will definitely consider using again in the future when developing applications that require the features supported.

Pros: A ton of features and it works perfectly.
Easy to implement.
Great support.
Great trial period.
Great reliability.

Cons: No cons, it works perfectly.
I wouldn't change anything for our perspective.

Overall: Great product.

Pros: Great modules to extend the functionality of your own software in terms of PDF editing. The support is absolutely fast and reliably helps with integration questions. I have been a customer for years and very satisfied with the company.

Cons: No negative aspects, i cannot tell anything negative.

Overall: Great modules to extend the functionality of your own software in terms of PDF editing. The support is absolutely fast and reliably helps with integration questions. I have been a customer for years and very satisfied with the company.

Pros: This is the only PDF manipulation library we found that is able to consolidate multiple copies of the same embedded font, and it does so very quickly. In our application, we create many separate PDFs, each with embedded fonts, then we merge those into a final PDF. Using this library, we're able to reduce the final document by over 60% (in one test case, from 3.4MB to 1.2MB.)

Cons: The only negative is the licensing model. The library is broken up into a number of modules that are separately priced on a per-document basis. This means that you only pay for the features you need, but you need to do a good up-front analysis to avoid multiple trips back to the well to add modules you didn't know you needed at the start.

I prefer a per-developer "all features" license, but we were able to reach a fair agreement.

Overall: Excellent. The pre-sales engineering support was outstanding. They put together a proof-of-concept for us to test the compression, and we were able to integrate that into our application with very little effort. The team was easy to work with, and the post-sale customer support has been proactive.

Pros: We like the ease of use, features, ability to customize, and support provided with PSPDFKit. Overall, the product has worked very well for us.

Cons: We did not have any major issues with PSPDFKit. Anything we discovered, support was able to help us find a solution.

Overall: We used PSPDFKit for a custom application for one of our customers. they were very happy with the features of the product.

Pros: This product is extremely well supported, documented and works amazingly on just about every platform required. packed with well documented features and extremely high performance as compared to other players in the market. This product has transformed the way we deal with PDFs and made life in development way way easier.

Cons: There is absolutely nothing we didn't like. Seriously compared to other players and in terms of the level of support for price and capability, there is nothing we would change.

Overall: The best experience with a PDF SDK to date after 8+ years of evaluating and using many others. I would highly recommend using this product and evaluating the online demo. I'm certain when you compare to other commercial offerings you will see a vast difference in performance and feature capability, well beyond expectations. The product support is amazing, and everyone is super responsive.

Pros: * Very responsive sales and support
* Reliable
* Lots of features
* Flexible API
* Easy-to-implement functionality

Cons: License fees are not clear. We had to do quite a bit of work figuring out what components we needed to add on and pay for.

Overall: PSPDFKit is a great PDF API for our document workflow. Shuffle. We have been very happy with their responsive support.

Pros: - Ease of integration
- Better than average documentation
- Great support
- Responsive to enhancement requests
- Commercially flexible

Cons: We could benefit from more flexibility in how menus are configured/customized.

Overall: We are a very happy licensee and planning to further our utilization and reliance upon the product.

Pros: PSPDFKit performs phenomenally for pdf use cases. Rendering, editing, signing, redacting, and other functions are straightforward to implement. Everything is configurable and all api options are well documented. Being able to fully integrate on a trial with a watermark made it easy to develop a proof of concept.

Cons: License cost is not immediately straightforward or available for purchase. Although this means you can get a pricing plan that is tailored to your needs, its a lot more manual that I expected.

Overall: Working with PSPDFKit was been a great experience. The tech is great and the team is extremely responsive. I'm very happy with the features we've already shipped with this SDK. I'm even more excited about what new features PSPDFKit will enable for us.

Pros: - Easy to use product with many applications.
- The best support.
- Their site has a lot of documentation to get you going.

Cons: There were absolutely no downsides to choosing the PSPDFKit SDK; it exceeded all our expectations.

Overall: PSPDFKit is great because it is simple to set up and use. What really makes them fantastic is their team and customer support. Even when I was just in the demo stage of getting their product and testing it, their developers team was with me every step of the way to answer any questions and helped me actually come up with better uses. This alone is what swayed me to choose them as the SDK I was going to use.

Pros: Comprehensive SDKs for iOS, Android and Web (we use them all).
Powerful PDF Annotation Tools.

Customer service.

Cons: Nothing worth mentioning. We think its a great tool.

Overall: Great tool, we've been using it for 6 years plus. PSPDFKit has always been a strong partner for us and we appreciate the effort they make to improve their feature sets every quarter.

Pros: 1. The best PDF rendition engine
2. Very easy to setup and integrate
3. Highly customizable
4. Great technical support
5. Pricing models are great
6. Very friendly sales team.

Overall: PSPDFKit is a great PDF rendition engine and very quick to setup and integrate.
Amazing sales and tech support team.

Pros: - Accurate
- Fast
- Flexible in terms of integration and deployment options
- Feature-rich
- Great support and account management team. They're reactive and close to their customers
- Fairly economical compared to competition

Cons: - Documentation can sometimes be confusing. Especially in terms of understanding pricing and product concepts / terms
- Support for React and NextJS could be taken a bit further with less hacks and guesses
- Uneasy for intermediate developers
- Server version deployment docs lack some details that require a good sysadmin / DevOps investigation to figure.
- A bit expensive but aligned with competition prices available on the market.

Overall: Working with PSPDFKit both on front-end, backend went smoothly without any major technical risks.
Can't wait for their cloud API to cover more features such as PDF to JSON.
Besides, working with their very patient and available pre-sales and support team was a real pleasure.
