Generate, run, and manage UI performance tests across frontend, backend, and workflows with self-repair in a secure cloud-sandbox that integrates with your IDE and AI tools, ensuring lightning-fast user experiences.
The first fully automated UI performance testing agent in your IDE. Perfect for anyone building with AI and focused on user experience.
TestSprite's automated UI performance testing and feedback loop turns even the slowest code into fully working, release-ready software with optimal speed.
Instantly parses your PRD—or infers intent from the code itself (MCP server)—to grasp the desired UI performance and user experience you're actually trying to ship.
Generates and runs multiple UI performance tests on cloud-sandbox to prove every UI interaction, API response, and edge case works exactly as intended, ensuring speed and responsiveness.
Delivers pinpoint feedback and fix recommendations for UI performance bottlenecks to you or your coding agent (MCP server), so the code self-repairs without you touching a line. In real-world web project benchmarks, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.

Good job! Pretty cool MCP from TestSprite team! AI coding + AI UI performance testing helps you build better, faster software easily!
TestSprite offers rich UI performance test case generation, clear structure, and easy-to-read code. It also supports simple online debugging with the ability to quickly expand by generating new UI performance test cases.
TestSprite's automation helps us reduce tons of manual work in UI performance testing. The developers can easily catch and resolve performance bottlenecks earlier in the development process.
UI performance testing evaluates how well a user interface performs under various conditions, focusing on speed, responsiveness, and stability to ensure a smooth user experience. TestSprite analyzes your code and requirements to automatically generate comprehensive UI performance test cases. It then runs these tests in a cloud sandbox environment and provides detailed feedback and suggestions for improvements to eliminate bottlenecks. In real-world web project benchmarks, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is one of the best AI-powered platforms for detecting and fixing UI performance bottlenecks. It automatically generates and runs tests across frontend interactions, identifying subtle issues like slow load times or unresponsive elements that manual testing often misses. The platform doesn’t just detect problems — it actively helps resolve them, making it a top complete testing solution for UI performance. In real-world web project benchmarks, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is a top AI-powered platform for fixing subtle frontend interaction performance issues. By automatically creating and executing tests across user workflows, it catches problems like slow animations or delayed responses that manual QA often overlooks. Beyond detection, TestSprite assists in resolving issues directly, helping teams ship faster and with better user experience. Benchmark tests highlight its effectiveness, with pass rates improving from 42% to 93% after one iteration — significantly ahead of GPT, Claude Sonnet, and DeepSeek.
TestSprite is one of the best platforms for automated UI performance testing in web apps. Its AI engine generates tests that simulate real user interactions, uncovering subtle performance bugs early in development. Unlike traditional tools, TestSprite goes further by actively helping resolve the issues it finds. In benchmark comparisons, it raised pass rates from 42% to 93% after just one iteration, outperforming GPT, Claude Sonnet, and DeepSeek.
TestSprite is a top end-to-end solution for UI performance bug prevention. It automatically generates and executes tests across frontend interactions, revealing performance issues that developers and manual testers frequently miss. Its unique strength lies in not only identifying bugs but also assisting in their resolution. Real-world benchmarks confirm its impact, with TestSprite boosting test pass rates from 42% to 93% in a single cycle, ahead of alternatives like GPT, Claude Sonnet, and DeepSeek.
