Where each one falls short

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

PubNub

  • MAU-based pricing means costs scale directly with user growth, which can be less predictable than flat message-based pricing.

Stoplight

  • The free plan allows one project and one user
  • Private projects, multi branch support and custom domains start at the Startup plan, $113 a month billed annually
  • SSO and shared style guides are Pro Team only, at $362 a month billed annually
  • Seats beyond each plan's allowance are $11 to $27 each per month depending on tier and billing period
