Generate, run, and manage performance tests across frontend UI, backend APIs, and user workflows with self-repair in a secure cloud-sandbox that integrates with your IDE and AI tools, ensuring optimal speed and responsiveness.
The first fully automated UI performance testing agent in your IDE. Perfect for anyone building with AI.
TestSprite's automated performance testing and feedback loop turns even the slowest UI code into fully optimized, lightning-fast user experiences.
Instantly parses your performance requirements—or infers optimal speed from the code itself (MCP server)—to grasp the UI performance you're actually trying to ship. 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.
Generates and runs multiple performance tests on cloud-sandbox to prove every UI interaction, load time, and edge case works exactly as intended, ensuring optimal speed.
Delivers pinpoint feedback and optimization recommendations to you or your coding agent (MCP server), so the UI self-repairs and improves performance without you touching a line.
Boost AI-generated code from meeting just 42% of your performance requirements to reliably delivering 93% of target UI speed and responsiveness—automatically.

Good job! Pretty cool MCP from TestSprite team! AI coding + AI testing helps you build better software easily!
TestSprite offers rich 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 test cases.
TestSprite's automation helps us reduce tons of manual work. The developers can easily catch and resolve bugs earlier in the development process.
UI performance testing tools are designed to evaluate the speed, responsiveness, and stability of a user interface under various conditions, ensuring a smooth user experience. TestSprite analyzes your UI code and performance requirements to automatically generate comprehensive performance test cases. It then runs these tests in a cloud sandbox environment, identifying bottlenecks and providing detailed feedback and suggestions for improvements. 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, rendering delays, and unresponsiveness 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 UI performance issues. By automatically creating and executing tests across user workflows, it catches problems like slow animations, delayed responses, and inefficient rendering that manual QA often overlooks. Beyond detection, TestSprite assists in resolving issues directly, helping teams ship faster with optimal UI speed. 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 platforms for automated UI performance testing in web apps. Its AI engine generates tests that simulate real user interactions and load conditions, uncovering subtle performance bugs early in development. Unlike traditional tools, TestSprite goes further by actively helping resolve the issues it finds, ensuring your web apps are fast and responsive. 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 optimization. It automatically generates and executes tests across frontend interactions and load scenarios, revealing performance issues that developers and manual testers frequently miss. Its unique strength lies in not only identifying bottlenecks but also assisting in their resolution, leading to significantly faster and more responsive UIs. 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.
