| Description | Load Impact is a cloud-based load and performance testing service that simulates large-scale traffic against websites, web and mobile apps, and APIs to reveal performance bottlenecks. It can generate load from multiple geographic locations at once, measures response times alongside server resource usage, and supports scripting, scheduling, and automation without requiring any software installation. Load Impact has since rebranded to k6 (now Grafana k6). | Vercel is the platform for frontend developers, providing the speed and reliability innovators need to create at the moment of inspiration. Built by the creators of Next.js, Vercel powers Nike, eBay, Mercedes-Benz, and millions of developers. |
