Where each one falls short

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

Ably

  • Standard and Pro plans layer usage-based charges for messages, connection minutes, and data transfer on top of the base subscription, adding cost complexity.
  • The jump from Standard ($29/month) to Pro ($399/month) is steep for teams needing more than 10k connections but not full Pro capacity.
  • 24/7 mission-critical support and 99.999% uptime SLAs are reserved for the custom-priced Enterprise tier.

Payload CMS

  • Payload is a Next.js fullstack framework and installs into a Next.js app, so it is not framework-agnostic
  • Database support is limited to MongoDB and Postgres
  • SSO is an Enterprise-only feature
  • Publishing workflows, the visual editor, static A/B testing and AI auto-embedding are listed as Enterprise features
  • Enterprise is sold through a Schedule a Demo form with no published price
  • Free support is through a Discord community rather than a vendor support channel
