Designed and built a lightweight yet feature-rich API testing tool that streamlines the process of crafting, sending, and inspecting HTTP requests. APILite features method toggles, header and query param editors, raw/form/x-www support, and a dynamic response viewer with syntax highlighting. Requests can be saved, organized, and re-executed via a built-in history manager. The application focuses heavily on user experience with dark-mode UI, intuitive animations, local storage persistence, and real-time validation feedback. Ideal for developers looking for a fast, clean, browser-based alternative to Postman.
