Where each one falls short

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

Poolside

No self-serve public application; access is largely through enterprise sales or third-party model gateways
Pricing for the flagship enterprise and government offering is not public and requires a sales conversation
Targets organizations with large (5,000+) developer headcounts, making it a poor fit for individuals or small teams
Documentation and product surface area are thin compared to consumer-facing coding assistants

Yarn

Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
Smaller ecosystem and community compared to npm, though still substantial
