Where each one falls short

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

Arize AI

The free plan caps trace spans at 25,000 per month with only 15 days of retention.
Self-hosted deployment and Data Fabric integration are restricted to the custom-priced Enterprise tier.
Pricing beyond the $50/month Pro plan requires a custom quote, making cost planning less transparent at scale.
Advanced compliance features like HIPAA are only available on Enterprise.

Grafana Cloud

Active Series (AS) billing model is difficult to predict and control; misconfiguration can cause sudden spikes and unexpected bills
Reduced control and customization compared to self-hosted Grafana instances
Data sovereignty concerns for organizations requiring on-premises data retention
Limited reporting types compared to traditional BI tools for compliance and audit requirements
