| ServiceStack's usage in OSS projects is covered in its License: https://github.com/ServiceStack/ServiceStack/blob/master/lic... i.e. It can be used as AGPL as-is, in addition it can be used in OSS projects under that license (to enable compatibility with the project) provided that the OSS Software remains OSS and provides complete source code for any additions. Although this AGPL/FLOSS Exception License only applies when you're creating your own distributions of ServiceStack from source code (i.e. very rare). This dual license option was added to allow OSS projects to use ServiceStack for free without paying for a commercial license, if that's not you, you can ignore this license option even exists. All ServiceStack packages on NuGet are released under the commercial license [1] of which only requires a developer license when it exceeds the free usage quotas [2] which are only in ServiceStack commercial products namely the ServiceStack Web Service Framework, OrmLite [3], ServiceStack.Redis [4] and PocoDynamo [5]. All other ServiceStack Software inc. all client libraries, inc. Serialization and ServiceStack.Common (containing #Script) are unrestricted libraries which can be used for free without a commercial Developers license in both commercial/non-commercial projects.
