Licensing Explained

  • The Chilkat License is a perpetual license that does not expire. However, the ability to update to newer versions expires when the license maintenance period expires. Chilkat will send a Renewal Notification email shortly before maintenance expiration.
  • New version upgrades are free while maintenance is not expired. Renewing provides the means to stay current with the latest versions of Chilkat. If maintenance lapses for more than 3 months, the license must be repurchased at the regular price.
  • The Chilkat components and libraries may be used on any number of computers or servers.
  • The license is royalty-free, meaning that Chilkat redistributables (DLLs and shared libraries) may be included with your application's deployment/installer packages.
  • Regardless of the type of license purchased, a Chilkat API can be used in any number of applications, and can be redistributed royalty-free with your applications to end-users.
  • Licensing levels are: 1-Developer, Small Group (up to 4-Developers), and Team (up to 8 developers).
