There is some interesting new working the C4 space at https://likec4.dev/

This is a less prescriptive model than structurizr but keeps the goals of C4

Most software architecture diagrams are a mess ... partly due to ad hoc notation, and partly because it's very unclear what the boxes represent. C4 resolves the latter problem by introducing a small number of predefined abstractions. This sounds limiting, but the power of C4 is that limited set of abstractions, and the conversations it forces architects/developers to have.

The less prescriptive approach of LikeC4 sounds very appealing, because it provides a way to define your own abstractions. But I don't recommend this approach for most teams -> https://c4model.com/abstractions/faq#can-we-add-more-abstrac...
