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.

Tabnine

No published free tier as of the current pricing page, unlike several competitors that offer free individual plans
Pricing is higher than many consumer-focused AI coding assistants, targeting enterprise budgets
Now owned by Tricentis, a testing-focused company, introducing uncertainty about long-term product direction outside quality engineering use cases
LLM usage costs apply separately when using Tabnine-provided model access, on top of the per-seat license fee
