Where each one falls short

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

7-Zip

  • Windows-centric GUI design; native graphical interface is Windows-only, with no first-class macOS or Linux GUI applications provided
  • Linux and macOS support primarily through command-line tools; no native file manager integration on these platforms
  • User interface design is dated compared to modern alternatives; visual feedback and UX polish lag behind commercial archivers
  • ARM64 support limited to Windows; no ARM64 build for Linux or macOS despite growing ARM adoption
  • No built-in cloud storage integration or synchronisation; cannot extract directly to Dropbox, OneDrive, or Google Drive

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
