ReqPad vs API & HTTP Client

ReqPad is the API client that Postman should have built for mobile. Test REST, WebSocket, GraphQL, gRPC, MQTT, and Socket.IO — all from your iPhone, iPad, or Mac. No laptop. No desktop app. No compromises. — WHY DEVELOPERS SWITCH TO REQPAD: You're on the train and staging is down. You're in a meeting and someone asks "is that endpoint returning the right schema?" You're in bed at midnight and a webhook isn't firing. With ReqPad, the answer is always the same: open your phone, test it, fix it, move on. — 6 PROTOCOLS, ONE APP: Most mobile API tools only handle REST. ReqPad handles six: • REST/HTTP — GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS with full header, body, and auth control • WebSocket — Real-time bidirectional messaging with live connection status • GraphQL — Query editor with syntax highlighting, variables, and subscription support • gRPC — Server reflection and .proto file support • MQTT — Connect to IoT brokers with QoS levels and topic subscriptions • Socket.IO — Test event-driven real-time communication ReqPad is the only mobile API client with gRPC and Socket.IO support. — ENTERPRISE AUTHENTICATION BUILT IN: Don't hack together auth headers manually. ReqPad supports: • Bearer Token & JWT • OAuth 1.0 & 2.0 (full flow) • Basic & Digest Authentication • API Key — header, query param, or cookie • AWS Signature v4 • Hawk Authentication • Akamai EdgeGrid Your staging environment uses OAuth? Your production API uses AWS Sig v4? ReqPad handles both without leaving the app. — GENERATE CODE IN 20+ LANGUAGES: Build your request visually, then export it as production-ready code: Swift, Kotlin, Python, JavaScript, Go, Rust, PHP, Ruby, C#, Java, Dart, cURL, and more. Perfect for prototyping, sharing with teammates, or dropping straight into your codebase. — IMPORT EVERYTHING, START IN SECONDS: • Postman Cloud Sync — Import your existing workspaces in one tap • cURL Import — Paste a cURL command and ReqPad builds the request • OpenAPI / Swagger — Import full API specs • HAR Files — Import browser network recordings • APIs.guru Directory — Browse and test 2,500+ public APIs instantly Already invested in Postman? You don't have to start over. Bring your work with you. — ORGANIZE LIKE A PRO: • Collections — Group requests into folders by project, team, or API • Environments — One tap to switch between dev, staging, and production • Variables — Use {{dynamic_variables}} in URLs, headers, and request bodies • History — Every request saved and searchable • Cookie Manager — Full visibility and control over stored cookies — DESIGNED FOR DEVELOPERS, NOT COMMITTEES: • Dark mode that actually looks good at 2am • Syntax highlighting for JSON, XML, and HTML responses • Response metrics — status, time, size at a glance • Clean, fast, no bloat — YOUR DATA STAYS YOURS: ReqPad is privacy-first. Your API keys, tokens, and request data live on your device. We don't track your requests, log your endpoints, or store your credentials on our servers. Period. — WHO REQPAD IS FOR: • Backend developers tired of switching to a laptop to test an endpoint • Mobile engineers who need to verify API responses on real devices • DevOps and SRE teams debugging production APIs from anywhere • QA testers running API checks without a full workstation • Full-stack developers who move between protocols daily — Free to start. No account required. Just open and test. Questions or feature requests?
