APILite is a compact, developer-focused HTTP client designed for fast iteration and low friction when developing and debugging APIs. It provides a clean request builder with method selectors, URL templates, header and query parameter editors, support for raw and form-encoded bodies, and pre-request scripts/hooks. The response viewer includes syntax-highlighted payloads, latency timing, and header inspection. Users can save requests into collections, replay them with variable substitution, and browse a history of executed calls. UX decisions prioritize speed: keyboard-first navigation, lightweight persistence in local storage, and optional cloud sync for saved collections. APILite also includes exportable HAR files and quick toggles for common auth schemes. The product aims to be a fast, usable alternative for developers who want a minimal, focused tool without compromising on the critical features needed for debugging APIs.
