Overview

Socials:

Kane CLI brings KaneAI into your terminal, IDE, or CI pipeline. Instead of writing brittle test scripts, you describe what should happen in natural language — Kane CLI executes the flow in a real browser and gives you a deterministic pass or fail with proof.

Built-in autoheal absorbs cosmetic UI changes that break traditional scripts, and vision-based dynamic waiting handles canvas, shadow DOM, and frameworks that resist DOM selectors. Every run uploads to Test Manager for replay and history, and any flow can be exported to native Playwright code.

It runs in three modes — interactive TUI, headless CLI, and agent mode with structured NDJSON output — making it the same tool for humans, scripts, and AI agents. One command (npx @testmuai/kane-cli-skill) installs it as a skill inside Claude Code, Codex CLI, and Gemini CLI.

Q&A

What is Kane CLI?

Rahul Jain

🛠️ 2 tools

wrote:

Kane CLI is a terminal-native AI testing tool from TestMu AI. You describe what should happen in plain English, and it drives a real Chrome browser, verifies each step, and returns pass or fail with a shareable evidence link. No selectors or brittle scripts required.

Who is Kane CLI for?

Rahul Jain

🛠️ 2 tools

wrote:

Developers, QA engineers, and "vibe coders" who want to verify flows without writing test scripts — and AI coding agents (Claude Code, Codex CLI, Cursor, Gemini CLI) that need a reliable way to verify their work in a real browser.

How do I install it?

Rahul Jain

🛠️ 2 tools

wrote:

npm install -g @testmuai/kane-cli (or brew install lambdatest/tap/kane-cli on macOS). Requires Node.js 18+ and Google Chrome. Then run kane-cli login and kane-cli --tui.

Is Kane CLI free?

Rahul Jain

🛠️ 2 tools

wrote:

The CLI is free to install. Usage runs on your TestMu AI account: a free tier gives 200 credits/month forever. Paid plans start at $19/month (Starter) and $99/month (Pro), with Enterprise available.

How is Kane CLI different from Playwright or Selenium?

Rahul Jain

🛠️ 2 tools

wrote:

Playwright and Selenium are code-based and need ongoing maintenance when the UI changes. Kane CLI works in plain English with built-in autoheal and vision-based waiting — and can export any flow to native Playwright code when you want it. They complement each other rather than compete.

Can I migrate my existing Playwright tests?

Rahul Jain

🛠️ 2 tools

wrote:

Yes. Kane CLI does two-way migration — ingest existing Playwright or Selenium scripts, run them as natural-language flows, and export back to Playwright. No rewrite from scratch.

What is Kane CLI?

Kane CLI is an AI-driven tool that focuses on browser automation for end-to-end testing. The tool uses Natural Language Interfaces for users to describe what they want it to do, such as logging in, accessing specific pages, verifying elements on the page, and more. It doesn't require any specific framework or selectors to work.

How does Kane CLI utilize natural language interfaces for browser automation?

Kane CLI uses Natural Language Interfaces to simplify end-to-end testing. Users simply describe in plain English what they want the AI to do — like accessing a particular page, verifying specific elements, or accomplishing a task. This removes the need for writing complex scripts, making the process user-friendly, non-technical, and highly efficient.

Which testing environments does Kane CLI support?

Kane CLI supports testing in multiple environments including a local browser environment, headless mode for continuous integration runs, and a visible mode for debugging. It's built to work seamlessly across these different environments, performing the same function with the same level of efficiency.

Can you describe the Autoheal feature of Kane CLI?

The Autoheal feature in Kane CLI is designed to absorb cosmetic UI changes that traditionally break scripts. Its aim is to provide resilience in the face of small changes to the website's design or layout, ensuring that tests don't fail due to these alterations. This helps in maintaining test accuracy and efficiency irrespective of the website's UI changes.

How does Kane CLI handle dynamic querying?

Kane CLI's dynamic querying feature deals with elements on the website dynamically instead of relying on hardcoded DOM selectors. It uses a vision-based dynamic waiting system to handle components like canvas, shadow DOM, and various frameworks that resist traditional DOM selectors. This ensures tests aren't affected by changes in these elements, making the testing process more robust and accurate.

How is Kane CLI integrated with Playwright Scripts?

Kane CLI can export any flow to native Playwright code. This means that the testing flows you create using the AI tool can be transformed into Playwright scripts. It offers users increased flexibility, particularly those versed in Playwright. This feature also provides a bridge between AI-created flows and more traditional scripting methods, offering versatility in test execution.

What operating modes does Kane CLI offer?

Kane CLI operates in three different modes for optimal accessibility. It offers an Interactive Text User Interface (TUI) for interactions right in your terminal, a headless mode for script and continuous integration pipeline execution, and agent mode with structured NDJSON output for use by AI agents.

Can Kane CLI handle OTP and CAPTCHA elements during testing?

Yes, Kane CLI comes equipped with the capability to negotiate OTP (One Time Password) and CAPTCHA elements during the testing process. This is part of its broad set of features designed to handle complex, real-world scenarios during end-to-end testing.

What are the benefits of using Kane CLI for non-technical users?

For non-technical users, Kane CLI provides a means to author, run, and verify testing flows without needing to code. Its Natural Language Interfaces allow users to describe what should happen, and the tool executes accordingly. This means a broader range of users, even those without coding experience, can effectively automate and optimize their testing processes.

Can I use Kane CLI for bug discovery and release confidence?

Absolutely. Kane CLI comes with features for deep bug discovery and instant validation. It executes user-specified flows in a real browser environment and provides a pass or fail outcome along with a proof. This helps increase the confidence in releases by ensuring all major flows work as expected.

Is it possible to prevent test duplication with Kane CLI?

Yes, with Kane CLI, you can execute the same flow against different URLs without having to duplicate scripts. This means if you have testing scenarios that need to be applied to different versions of the site (like beta, staging, and production), you can easily do it without creating multiple test scripts. This makes the testing process much more efficient.

How do I install Kane CLI as a skill inside Claude Code, Codex CLI, and Gemini CLI?

To install Kane CLI as a skill in Claude Code, Codex CLI, or Gemini CLI, you simply need to run a single command 'npx @testmuai/kane-cli-skill'. This installs it as a skill inside these IDEs making the integration process simple and straightforward.

Does Kane CLI support running tests against different URLs?

Yes, Kane CLI supports the execution of the same testing flow against different URLs. This feature prevents the need for duplicating scripts while still allowing for comprehensive testing in different environments or versions of your website. This feature makes test execution more efficient as identical flows do not need to be rewritten for different URLs.

What is the agent mode with structured NDJSON output in Kane CLI?

The agent mode with structured NDJSON output in Kane CLI is designed for use by AI agents. This mode outputs the testing results in a structured NDJSON format providing detailed insights and ensuring that the results are easy to parse for subsequent processing or analysis. It's an effective way of interfacing Kane CLI's testing capabilities with other AI tools in your workflow.
