Vellum was designed and built from scratch for the professional web publishing industry. It is not a re-hash of existing platforms or ideas.
With features such as dependency tracking and custom presets, images are treated as first class citizens in Vellum.
Modify a content template without breaking existing content. No coding required.
Vellum provides you with user-defined endpoints, so you're not managing content using API calls.
Vellum is in private release - but we can let you know when it goes live.
