ReqPad - API Client & Tester

ReqPad is the API client that Postman should have built for mobile. Test REST, WebSocket, GraphQL, gRPC, MQTT, Socket.IO and MCP — with built-in AI — 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.

7 PROTOCOLS, ONE APP:

Most mobile API tools only handle REST. ReqPad handles seven:

• REST/HTTP — every method with full header, body, and auth control, plus Server-Sent Events streamed live; Send as a Browser for sites that only answer browsers
• 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
• MCP — Connect to Model Context Protocol servers: call tools, read resources, run prompts

ReqPad is the only mobile API client with gRPC and Socket.IO support.

REQPAD AI — AN API EXPERT ON EVERY SCREEN:

• Explain any failure — a 4xx, a GraphQL error, a refused WebSocket or a gRPC status — with the cause and a one-tap fix
• Describe a request in plain words — ReqPad AI fills in the method, URL, headers and body
• Write messages and queries — GraphQL from your schema, WebSocket, Socket.IO and MQTT messages, gRPC messages from the proto, MCP tool arguments
• Write tests for the response you just got
• Ask the JSON a question — get a JSONPath filter

You see exactly what is sent before it is sent, and secrets are removed on your device first.

SCRIPTS & AUTOMATION:

• Pre-request and test scripts with the Postman-compatible pm.* API
• Collection Runner — run whole collections with CSV/JSON data files and a report
• OAuth 2.0 flows with automatic token refresh
• Secret variables kept in secure storage
• JSON tree view with JSONPath filtering

—

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

• History — Every request saved and searchable
• Cookie Manager — Full visibility and control over stored cookies

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. ReqPad AI is optional and sends only what an action needs, after you see it.

Free to start. No account required. Just open and test.
