Could you build this?
Partial Markdown notes, graph view, and canvas are buildable with AI help, but a credible Obsidian alternative needs a mature live-preview editor and a stable plugin API with an ecosystem.
What it would actually take: The core is a local-first markdown editor (for example CodeMirror or ProseMirror) with a file-watching sync layer, plus graph and canvas rendering on d3 or a canvas library. The hard parts are a robust editor with live preview and link resolution, a sandboxed plugin system that third parties can rely on, and sustained maintenance effort over years.
