Where each one falls short

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

Appsmith

  • The free cloud tier is capped at 5 users, 5 workspaces and 3 Git repositories
  • Workflows, custom roles and audit logs all require the Business plan at $15 per user per month
  • SAML and OIDC single sign-on need Enterprise, which starts at $2,500 a month with a 100 user minimum
  • Embedding an app privately is Enterprise only; the lower tiers embed publicly
  • Managed hosting is an Enterprise add-on rather than an included option

Swagger UI

  • Only as good as the specification: a thin OpenAPI file produces thin documentation
  • Default presentation is dated compared with modern documentation tools
  • Large specifications render slowly and become hard to navigate
  • Try it out against production needs care with authentication and CORS, and is often disabled as a result
