Hi, have you considered licensing the SDKs with MIT or Apache 2.0?
@openpanel/web has no license according to NPM and the repos of the other SDKs (swift, kotlin) are AGPL 3.0 which to my understanding means they infect the codebase in which they are used in, making it impossible to use them not only in selfhosted but also your hosted service.
Releasing the SDKs with a permissive license would help your customers who do not want to opensource their code.
