Where each one falls short

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

Celigo

  • Prices are not published on any of the three editions
  • Billed on endpoints and flows, so the cost is driven by how many systems you connect rather than by volume through them
  • API Builder, lookup caching and a sandbox all require the Professional edition
  • Single sign-on is optional on Standard and included from Professional up
  • Unlimited endpoints and the full governance features are Enterprise only

Vellum

  • Pricing varies significantly by computational tier, making budget planning difficult
  • Requires explicit permission for sensitive actions, limiting autonomy
  • Self-hosting option may intimidate non-technical users
  • Learning curve to develop customizations with plugins
