npn.dev vs APIOrbit

npn helps you explore and test HTTP apis, with a focus on speed and correctness

A fast, native REST & GraphQL client with AI assistant, built for iPhone and iPad. APIOrbit helps you send requests, debug responses, test endpoints, and generate documentation — all with AI. Import your Postman collections, explore data in a powerful JSON viewer, and keep everything in sync with iCloud. Unlike browser-based tools, APIOrbit is built entirely native. It handles large responses seamlessly, lets you preview images, PDFs, video, audio, and live streams right inside the app, and works offline with your synced collections. KEY FEATURES REST & GraphQL Send any HTTP method. Configure headers, query params, authentication, and all body types — JSON, form URL-encoded, multipart with file attachments, and binary. Full GraphQL support with query editor and variables. AI Assistant Generate data models in 9 languages — Swift, TypeScript, Kotlin, Java, Python, C#, Go, Rust, and Dart. Customize generation settings per language. Create mock request bodies, API documentation, and response summaries. JSON Tree & Search Explore complex responses in a structured, searchable tree. Find any key or value instantly. Filter with JSONPath expressions. Copy any node or value with a tap. API TESTING Turn any request into a test. Attach expectations — status code, response time, headers, JSON values via JSONPath, or body contents — and APIOrbit checks them automatically after every run. JSON bodies are compared structurally (key order is ignored), with content-type-aware matching for XML, HTML, and text. Get an instant pass/fail badge on each response and a dedicated Tests tab with full expected-vs-actual details, or run every request in a collection at once for a complete pass/fail summary. Import Collections Import from Postman (v2.0/v2.1), OpenAPI 3.x, Swagger 2.0, and cURL. Switch from Postman in seconds — your docs come along too. Media Preview View images, PDFs with page navigation, video, audio, and HLS streams directly in the app. No export needed. Debugging & Metrics Monitor DNS lookup, TLS handshake, request and response timing, content size, SSL details, and network protocol. See per-step metrics for every redirect in a chain. iCloud Sync Collections sync across iPhone, iPad, Mac, and Vision Pro automatically. Collection Variables Define reusable variables for URLs, headers, auth fields, and body — applied at execution time. Authentication Basic Auth, Bearer Token, and API Key — with header or query placement. Accessibility Full VoiceOver support across the entire app. Dynamic Type. Dark mode.
