Basically this means the software is

  • Free to own
  • Free to use
  • Free to modify (the source code to suit your needs, if you want)


All the source code for Chromis products will be made available on Github. This does not include source code for any external library files, which may be found else where on the internet.

Our policy is to issue the source code, on the same day of release of a new version. This enables us to work on features and release them when we are happy, We will look at any forks of the project and if we think it provides features, that we think may be of benefit to the majority of users, there will be consideration given about including it as part of the official release.
