API Client is a fast, native HTTP client built for developers who want to explore APIs without the bloat. Organize your requests into collections, send them with one tap, and inspect every detail of the response — all in a clean interface designed for iPhone, iPad, and Mac. ORGANIZE WITH COLLECTIONS Group requests into named collections for each project or API. Reorder, bulk-select, and delete with ease. Each collection supports default headers that are automatically merged into every request, so you never have to repeat shared configuration. Build any HTTP request without limits: • Methods: GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS • Headers editor in YAML, JSON, or key-value rows — switch between formats at any time • Body types: JSON, XML, plain text, SPARQL, URL-encoded form, multipart form, and raw binary file upload • Per-request and per-collection proxy support (HTTP, HTTPS, SOCKS5) with username/password authentication • Import from a curl command — just paste and go RICH RESPONSE VIEWER See exactly what the server returned: • Status code, content type, and response time at a glance • Response body in JSON (with pretty-print), HTML preview, XML, JavaScript, raw, hex dump, or base64 • Inline image preview for image responses • Collapsible response headers, request trace, and URLSession debug log • Save or share the response body as a file EXPORT CODE IN 20 LANGUAGES Generate ready-to-use code for any request in Shell (curl), Python, JavaScript, Node.js, Swift, Go, PHP, Ruby, Java, Kotlin, C#, Rust, PowerShell, R, C, Clojure, Crystal, Objective-C, OCaml, and raw HTTP. Copy to clipboard in one tap. HAR IMPORT & EXPORT Import HTTP Archive (HAR 1.2) files to recreate a collection of requests in seconds — great for replaying browser sessions or sharing test suites. Export any collection or individual request as a HAR file for use in other tools. ICLOUD SYNC Your collections and requests sync automatically across all your devices via iCloud. Start a request on your iPhone, refine it on your Mac. BUILT FOR APPLE PLATFORMS API Client is a fully native SwiftUI app that feels right at home on iOS, iPadOS, and macOS. It respects your system appearance, supports the sidebar/detail split view on larger screens, and adapts to the compact single-column layout on iPhone. No subscriptions. No accounts. No tracking. Just a solid API client.
