Limetest is the most light weight end to end testing framework with AI capabilities that can run in your CI workflows. Define your test cases in natural language and let AI handle the execution.
- Optimized for AI: Define your test cases in plain language and let AI execute them end to end.
- Lightweight & Efficient: Leverages Playwright snapshot instead of pixel analysis for faster, more reliable execution.
- Vision Capabilities: Falls back to vision mode when snapshot mode fails during more sophisticated test scenarios.
npm install @limetest/limetest
npx playwright installlimtest will launch Chrome browser with the new profile, located at

A Model Context Protocol (MCP) server powered by Playwright that allows your MCP client to perform end to end validation its own changes.
- Automated testing planned and executed by LLMs
After cloning this repo, build and add the E2E MCP server to your MCP Client as such: Notice that you need OpenAI API key to run this MCP server in end to end mode.
npm install @limetest/mcp
npx playwright installThen:
{
"mcpServers": {
"limetest": {
"command": "npx",
"args": [
"npx @limetest/mcp",
"--api-key=<your openai api key>"
]
}
}
}All the logged in information will be stored in that profile, you can delete it between sessions if you'd like to clear the offline state.
