It could be interesting to separate the visualization functionality from the syncing/sharing aspect.

For example, if you store the schema representation as a logical dump (CREATE statements) in a git repo, syncing/sharing becomes trivial. This also provides a branch workflow for collaborative editing, and the commit history serves as an authoritative changelog.

From this point of view, it could be compelling to have an offline visualization tool that simply operates on top of the current local filesystem state of a repo. Ideally this could be paired with a self-hosted server/daemon that can generate a visualization of any arbitrary commit of a remote repo on GitHub, GitLab, etc.

Disclosure: I'm the author of an open source schema management tool https://skeema.io which is designed to support a repo-driven workflow for DDL execution. So I have a heavy bias towards storing schemas declaratively, as repos of CREATE statements.
