Open Source Licenses
Kasimir stands on the shoulders of excellent open source software. Here we transparently list every component the platform builds on.
The libraries we use are almost entirely published under permissive open source licenses (MIT, Apache-2.0, BSD). The complete list of all direct production dependencies is shown below — generated automatically from our package manifests.
The entire editor and collaboration stack (TipTap, Yjs, Hocuspocus) is fully open source and self-hosted by us — no editor content ever leaves our EU infrastructure.
