API Client is a fast, native HTTP client built for developers who want to explore APIs without the b
loat. 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.
