Agent tests need state, not transcripts.

## What it does

Sparta’s Worlds is an AI-agent test environment that creates a sealed copy of systems such as Zendesk, Stripe, Shopify or Salesforce. The homepage says it keeps state, runs the agent against the twin, then grades what changed against what should have changed. It names failures injected, database state and byte-for-byte replay as the evidence surface.

The pricing page lists a free plan with one world and unlimited runs on the customer’s machine. The Team plan is $400/month and adds every world in the catalog, several worlds in one environment, multi-agent chains and CI integration. These are dated page observations; they are not proof of test quality.

The docs make the integration boundary unusually clear. They describe a ten-minute path from local world to CI, but also say the current dashboard is not part of the published `sparta_worlds@0.8.0` package used by the commands on the page. That caveat belongs in the buying decision.
