The short version

  • Only Obsidian has a free tier, so it costs nothing to try first.
  • Each has a real cost: Obsidian sync is a paid add-on at $4 per month billed annually rather than part of the app; Sketch macOS-only for editing, blocking Windows and Linux users from accessing design features
  • They diverge on capability: Obsidian covers Bidirectional linking, Sketch covers Vector editing.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Obsidian

  • Sync is a paid add-on at $4 per month billed annually rather than part of the app
  • Publishing to the web is a further $8 per month per site
  • Commercial use asks for a $50 per user per year licence, though the vendor states it is not required
  • Collaboration is limited compared with a hosted notes tool, since the vault is local files first

Sketch

  • macOS-only for editing, blocking Windows and Linux users from accessing design features
  • Real-time collaboration feels less seamless than Figma with occasional sync delays
  • Limited built-in image editing capabilities, requiring external software for bitmap work
  • Subscription required for cloud features and collaboration, losing access if subscription lapses
