Dyalog Pricing and Licences

Fair and Transparent

Although Dyalog APL is free for non-commercial use, we have supported APL for nearly four decades, and believe that it is the long term interests of our users that they contribute to our research, development and support efforts. We publish a variety of pricing models and are happy to negotiate if none of them fit the way your business is organised.

We believe in not just selling a licence but a service where Dyalog helps you.
