The full-power API client in your pocket.
REST, GraphQL, gRPC, MQTT, WebSocket, Socket.IO & MCP — with real auth and built-in AI. No laptop required.
Free to start. No account required. Just open and test.
Debugging at 11pm? On a train?
“It’s such a pain to have to open my laptop every time…”
Not anymore.
Seven protocols, one app
Most mobile API tools stop at REST. ReqPad doesn’t.
REST / HTTP
GET to QUERY with full header, body, and auth control — and Server-Sent Events streamed live.
WebSocket
Real-time bidirectional messaging with live connection status.
GraphQL
Query editor with syntax highlighting, variables & subscriptions.
gRPC
Server reflection or .proto files; unary, server, client and bidirectional streaming — on a phone.
MQTT
IoT brokers with QoS levels and topic subscriptions.
Socket.IO
Test event-driven real-time communication anywhere.
MCP
Connect to Model Context Protocol servers: call tools, read resources, run prompts.
The only mobile client with gRPC & Socket.IO.
The real app, not a mockup
Every protocol gets its own tools.
ReqPad AI
An API expert on every screen.
Say what you need in plain words — or ask why something failed. ReqPad AI works in every protocol and shows you exactly what it will send before it sends anything.
- 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 — “weather in Istanbul for the next 3 days” becomes the method, URL, headers and body.
- Write messages and queries — GraphQL queries from your schema, WebSocket, Socket.IO and MQTT messages shaped like the ones on the connection, gRPC messages from the proto, MCP tool arguments from their schema.
- Write tests — post-response tests for the response you just got.
- Ask the JSON — a question in plain words becomes a JSONPath filter.
- Fix settings in one tap — SSL verification, redirects, URL encoding, Send as a Browser, Socket.IO and MCP transport — the AI knows the request as ReqPad sends it.
Secrets are removed on your device first. 5 free actions a month — 300 with Pro.
Scripts & automation
Script it, test it, run the whole collection.
- Pre-request & test scripts — Postman-compatible pm.* scripts, with test results for every request.
- Collection Runner — run a whole collection with CSV or JSON data files, flow control and a run report.
- OAuth 2.0 flows — authorization code with PKCE, client credentials and password, with automatic token refresh.
- Send as a Browser — send HTTP and GraphQL with a real Chrome fingerprint, so sites that only answer browsers respond.
- Secret variables — kept in the device’s secure storage and masked everywhere.
- JSON tree view — browse huge responses and filter them with JSONPath.
- Server-Sent Events — watch streamed responses arrive event by event.
Enterprise auth, built in
Stop hand-crafting auth headers on a phone keyboard.
Staging uses OAuth2, production signs with AWS SigV4? ReqPad speaks both — and seven more — without leaving the app.
Import everything
Already invested in Postman? Bring your work with you.
- Postman Cloud Sync — import your existing workspaces in one tap.

Now on Android
iPhone, iPad, Mac — and Android.
ReqPad is live on the App Store and Google Play. Same seven protocols, same enterprise auth, same local-first data — now on your Android phone and tablet too.
Your data stays yours
No ads. Your API data stays on your device.
API keys, tokens and request history stay on your phone — we never see your requests, log your endpoints, or store your credentials on a server. ReqPad AI is opt-in: it sends only what an action needs, after you see it, with secrets removed. Built by an indie developer who uses it every day, not a committee.
FAQ
Questions developers actually ask
Is there an official Postman app for iPhone?
No — Postman does not ship a mobile client. ReqPad fills that gap: import your Postman workspaces via Cloud Sync and keep working from your phone or tablet, without starting over.
How do I test gRPC from my phone?
ReqPad is the only mobile API client with gRPC support. Use server reflection or load your .proto files, make unary, server-streaming, client-streaming and bidirectional calls, and inspect every message — directly from your phone.
How much does ReqPad cost?
Free to start, no account required: REST/HTTP and WebSocket are free forever. ReqPad Pro unlocks GraphQL, gRPC, MQTT, Socket.IO and MCP, scripts and the Collection Runner, advanced authentication, imports, code generation, Send as a Browser and 300 AI actions a month — $3.99/month, $24.99/year, or $59.99 once for lifetime access, with a 7-day free trial.
Does ReqPad have AI?
Yes. ReqPad AI explains failures with a one-tap fix, writes requests, messages and GraphQL queries from a plain-language description, writes tests and turns questions into JSONPath — in every protocol. It is optional: before the first use you see exactly what will be sent, and secrets are removed on your device first. Free users get 5 AI actions a month; Pro includes 300 a month.
Can I run my Postman scripts?
Yes. Pre-request and test scripts use the Postman-compatible pm.* API, and the Collection Runner runs whole collections with data files, flow control and a report.
Where does my API data live?
On your device. ReqPad does not track your requests, log your endpoints, or store your credentials on any server. Collections, history and environments stay local. Only if you use ReqPad AI is the data that action needs sent for processing — after you see it, with secrets removed.
