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.
