Where each one falls short

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

Anyword

  • Performance predictions, the feature the product is built around, are rationed: 50 a month on Starter at $49 and 100 on Data-Driven at $99
  • Data rows are capped at 50 on both published tiers, so custom data needs the Business plan
  • Starter is a single seat
  • Custom AI models and SSO require Business or Enterprise, both quote-only
  • The trial is 7 days and 2,500 words, and no refunds are offered

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.
