Kane CLI by TestMu AI

Kane CLI is a terminal-native browser testing tool built for developers, QA engineers, and AI coding agents. Describe a browser flow in plain English and Kane CLI executes it in a real Chrome browser, verifies every step, and returns a clean pass or fail. No selectors to write, no test scripts to maintain, no framework to learn from scratch.

Who It Is For

Kane CLI is designed for two audiences simultaneously. For developers and QA engineers, it provides a fast verification loop — run a browser flow from the terminal before opening a PR, before a deploy, or before a QA handoff. For AI coding agents like Claude Code, Codex CLI, Cursor, and Gemini CLI, it is a browser verification primitive — the tool agents call when they need to confirm that what they built actually works in a real browser end to end.

Three Execution Modes

Kane CLI ships with three modes to fit every workflow. Interactive TUI keeps the browser open between runs so session state carries over, useful for development and exploratory testing. Headless CLI runs flows with no visible browser and produces a deterministic exit code for shell scripts and CI/CD pipelines. Agent mode outputs structured NDJSON line by line, purpose-built for AI coding agents to consume and act on programmatically.

What Makes It Different

The automation engine is vision-based rather than selector-based. It identifies elements by what they look like on screen, not by CSS classes or DOM position, making it resilient to the UI changes that break traditional automation tools. Built-in autoheal and smart waiting handle loaders, animations, shadow DOM, and dynamically rendered components without extra configuration.

Test.md is Kane CLI's agent-native test format. Any session can be captured as replayable markdown that is human-readable, version-controllable, committable to a repository, and executable by AI agents. Flows can also be exported to native Playwright scripts or imported from existing Playwright and Selenium test suites in either direction.

Setting up an AI coding agent to use Kane CLI takes one command: npx @testmuai/kane-cli-skill. This installs a skill file that tells Claude Code, Codex CLI, or Gemini CLI exactly how to call Kane CLI and interpret its structured output — no manual configuration required.

Every run generates a persistent shareable evidence link with session recording, step-by-step logs, and full network capture, synced automatically to the KaneAI Test Manager dashboard.

Pricing

Free tier includes 200 credits per month with no expiry — enough to evaluate the tool end to end. Paid plans start at $19 per month. Enterprise is available with SSO, IP whitelisting, and compliance support.

Available on macOS (Apple Silicon and Intel), Linux x64, and Windows x64.

Install with: npm install -g @testmuai/kane-cli
