Overall they are a great partner to trust all our licensing needs to. If you need to send them a support email, a senior technical staff member will answer back in no time. I can only hope that the Microsofts, Googles and AWS of the world would be as responsive and pro-customer as KeyGen is!

Integration with our product was fast, all the licensing requirements that we needed were easily implemented with KeyGen. Support to get this done was superb, documentation is clear, and they keep on adding features that we found appealing and thus allow us to improve our licensing model on a regular basis. Pricing is very reasonable and the platform is super reliable (HA)! We could not ask for more from KeyGen!

The built-in reporting tool could be more configurable, maybe have filters to see which licenses are due each week/month. But we can do those queries through the API, to feed a dashboard of our own, so not a real issue. When we started 3+ years algo implementing customized feature activation on a license and off-line licensing were not available. But all these have been addresses and now it rocks!

I like how robust the API is. And the documentation is very thorough. I had a custom WooCommerce plugin developed, to communicate with a custom solution on my licensing server, that interacts with Keygen to help manage our user's software license for macOS desktop apps

I would like to be able to set up a notification system for errors in API requests

The team/[SENSITIVE CONTENT] is exceptionally responsive.

It's sometimes too slow to upload/download artifacts.

Using Keygen saved me the trouble of building and maintaining my own licensing server and strategy. It is easy to work with, reliable, and affoardable.

Keygen is one of the rare products that is legitimately satisfying to work with. It's obvious that the creator cares deeply about the quality of the product. From my own experience there are so many things that work well: - the interface is well designed - the API is flexible, logical and easy to work with - the documentation is clear and comprehensive - there are a wide array of well documented implementation examples on GitHub - the product is in active development - support is responsive and unusually helpful I'm the solo designer/developer of a well known design tool. When I decided to switch to subscription pricing, I began building my own licensing server. Part way through the process I learned about Keygen. After reading through the documentation and speaking to support about my goals, I immediately abandoned my own licensing server in favor of cloud functions and Keygen. I have zero regrets.

Since Keygen is billed monthly, it's most viable for services that also have some sort of recurring billing, or that have a reliable revenue stream. Hobbyist developers will probably have a hard time justifying the cost, despite how good the product is. I mention this more as a heads-up to those investigating than as a negative, as I don't think there would be any other way for Keygen to make money that would also be useful for one-time-purchase software.

I found Keygen to be incredibly comprehensive and reliable. The documentation is extremely detailed and provides all information needed to implement a licensing solution. The product is dynamic and allows flexibility and customization in implementation. All features documented behave exactly as described, and the code examples for every single action are very comfortable to work with. Customer support is excellent. I highly recommend it.

The documentation. The node-based approach provides many solutions to a single problem. The control panel is very user-friendly, intuitive, and easy on the eyes. The entire product is very consistent in approach, which makes implementation very intuitive.

The only thing I found to be a disadvantage is the lack of batch-processing ability. There isn't a way through the control panel to perform actions on multiple objects at once. Also, I think that maybe the metrics dashboard would have been nicer if there was full history data as well as an ability to search/customize graphed data according to needs.
