CARBON framework beta

Define tests locally. Steer the plan. Scale selected runs in the cloud.

CARBON learns your code, UI, APIs, AI features, states, and flows; creates risk-ranked intent tests; executes with your coding agent; and turns screenshots, network traffic, console output, traces, and results into confidence and remaining-risk reporting.

  • Generate and manage intent-based regression and exploratory tests
  • Review scope, depth, personas, risk coverage, and cost before execution
  • Run locally by default, or connect selected plans to testers.ai cloud

AI THAT TESTS YOUR WHOLE SITE

You steer. The AI does the work.

AI drafts the plan — then every widget is yours. Dial the run up or down and add your own tests. Nothing runs that you didn't choose.

First, you steer the plan.

AI analyzes your site and drafts a plan — then you configure it. Every widget is a decision you make — features, checks, personas, tests and bots. Dial it up or down; nothing runs that you didn't choose.
