Where each one falls short

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

Bruno

  • Native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month
  • OpenAPI syncs are capped at 5 a month on the free tier
  • SSO, SCIM and user management require Ultimate at $11 per user per month
  • Private workspaces are a paid feature
  • Advertised prices are annual rates

Sphinx

  • reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown
  • Configuration is complex and the default output is dated-looking without theme work
  • Build times on large documentation sets are slow
  • Heavier than the problem for a small project that only needs a few pages
