Improving React page performance with AI agents (www.metaview.ai)

A developer successfully utilized AI agents to enhance the performance of a complex React application, achieving a remarkable ~76% reduction in p95 frame time. The application, which streams AI-generated messages in real time, originally suffered from poor performance on lower-spec hardware due to its intricate design. By employing Cursor's AI agent, Claude Opus 4.5, the developer implemented a systematic approach to test and optimize the page performance, creating an event recording and replay harness that facilitated accurate benchmarking to assess the effects of various code changes. This development is significant for the AI/ML community as it highlights the accelerating capabilities of AI in software engineering, potentially reducing human involvement in coding tasks. Key optimizations included replacing Framer Motion layout animations which hindered performance, and shifting from React Context to Zustand for managing state, resulting in improved rendering efficiency. Overall, the experience emphasizes how rapidly evolving AI technologies can drastically streamline the software development process, allowing developers to focus more on high-level strategy rather than extensive manual coding.
