In summary, I created a high-performance marketing site for Requestly, an open-source HTTP interceptor backed by Y Combinator. The site, built using Webflow, highlights the key features and benefits of the tool, which include overriding API responses, redirecting URLs, creating API mocks, modifying HTTP headers, and capturing HTTP sessions. The marketing site targets web developers, QA engineers, API developers, and anyone who needs to test, debug, or modify web applications. The project showcases Requestly's powerful capabilities and user-friendly interface, making it an attractive tool for its target audience.
