Seamlessly Integrates With Your Favorite AI-Powered Editors
Optimize What You Build
TestSprite's automated performance testing and feedback loop turns even the most unoptimized code into fully working, release-ready software that performs under load. 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.
Understand Performance Goals
Instantly parses your performance requirements—or infers intent from the code itself (MCP server)—to grasp the scalability you're actually trying to ship.
Validate Load Capacity
Generates and runs multiple load and stress tests on cloud-sandbox to prove every UI, API, and edge case performs exactly as intended under various traffic conditions.
Suggest Performance Fixes
Delivers pinpoint feedback and optimization recommendations to you or your coding agent (MCP server), so the code self-repairs for better performance without you touching a line.
Deliver Scalable Performance
Boost AI-generated code from meeting just basic requirements to reliably delivering high-performing, scalable features—automatically.
