Where each one falls short

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

Liveblocks

  • On the Free plan, each metered feature has a hard cap and simply pauses when exceeded rather than allowing overage.
  • The jump from Pro ($30/month) to Team (starting at $600/month) is steep for teams that outgrow Pro but don't need full Team scale.
  • Multi-region hosting and SCIM provisioning are Enterprise-only and require custom pricing.

Stainless

  • Starter and Pro plan prices are not published and require contacting the company.
  • The free plan caps APIs at 25 endpoints, which excludes larger production APIs.
  • Overage charges apply per SDK/endpoint/month once limits are exceeded, which can make costs unpredictable at scale.
