What is CARBON by testers.ai?
CARBON is a testing plugin from testers.ai that adds an AI test manager called Jay to coding agents such as Claude Code, Codex and Cursor. Jay coordinates risk-based checks, exploratory testing and accessibility reviews, and keeps evidence for every finding.
The free Core edition is MIT-licensed and ships 12 testing commands. You install it as a native plugin in Claude Code or Codex, or as a local MCP server through npx for Cursor, Antigravity and other MCP hosts, which requires Node.js 22 or later. It works with the frameworks and tools your agent already has.
Supported stacks include Selenium, Playwright, pytest and Appium, code in Java, Python, TypeScript, JavaScript and C#, issue trackers like Jira, GitHub Issues and GitLab, test management in TestRail and Xray, and device clouds such as BrowserStack and Sauce Labs. Pro adds dozens of deeper testing workflows.
