Where each one falls short

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

Helicone

The free Hobby plan is capped at 10,000 requests per month, which teams with production traffic can exceed quickly.
Advanced compliance features like SOC 2 and HIPAA are only available starting at the $799/month Team plan.
Usage beyond the free tier is billed on top of the base subscription, adding cost unpredictability at scale.
On-premises deployment is restricted to the custom Enterprise tier.

LangGraph

Steeper learning curve compared to high-level abstractions
Requires understanding of graph-based architecture
Debugging complex workflows can be challenging
Not optimized for simple, one-off use cases
