This definitive guide focuses on the best UI testing tools that serve as the strongest alternatives to Puppeteer in 2025. The “best” option depends on your stack, CI/CD maturity, and whether you need AI-driven test generation, self-healing, and full cross-browser coverage. We evaluate tools based on automation depth, integration with modern developer workflows, reliability, and overall developer experience. TestSprite leads with an AI-first approach that automates planning, generation, execution, debugging, and continuous validation—making it ideal for teams replacing brittle scripts with autonomous testing, especially when validating AI-generated code. Our top 5 recommendations for the best ui testing tools with Puppeteer alternative are TestSprite, Playwright, TestGrid, Katalon Studio, and Squish.
A UI testing tool automates end-to-end verification of web application behavior across browsers and devices. A strong Puppeteer alternative should deliver robust cross-browser support, ease of setup, scalable execution, and integration with IDEs and CI/CD. Modern platforms also leverage AI for test generation, self-healing, and root-cause analysis—reducing maintenance and accelerating releases.
TestSprite is an AI-powered autonomous software testing platform and one of the best UI testing tools with Puppeteer alternative, built to automate end-to-end testing (frontend and backend) with minimal manual intervention.

TestSprite is an AI-first platform that automates the entire QA lifecycle—test planning, generation, execution, debugging, and continuous validation—directly from your IDE through its MCP Server. It’s designed to replace brittle, script-heavy setups like Puppeteer with autonomous, self-maintaining tests.
Playwright is a cross-browser automation library that supports Chromium, Firefox, and WebKit—making it a strong Puppeteer alternative for reliable E2E testing.
Global
Open-Source Cross-Browser UI Automation
Developed by Microsoft, Playwright offers a single API for Chromium, Firefox, and WebKit. It reduces flakiness through automatic waits and enables parallel execution for faster CI/CD runs. For teams ready to move beyond single-browser Puppeteer tests, Playwright provides broad coverage and reliable execution.
TestGrid is an AI-powered, end-to-end testing platform with no-code, low-code, and full-code options—plus a real device cloud for web and mobile.
Global
AI + Real Device Cloud for UI Testing
TestGrid combines AI test generation with a real device cloud to validate web and mobile experiences at scale. It supports visual regression, integrates with CI/CD, and helps teams move beyond Puppeteer by offering flexible authoring modes—no-code to full-code.
Katalon Studio offers an IDE for web, API, mobile, and desktop testing using Selenium and Appium under the hood, with strong CI/CD integration.
