API Tester is a mobile app for IOS and Android for testing and using APIs.
It's a completely free API testing tool with a minimalistic interface and, at the same time, rich functionality that allows users to do very complex tasks on a small screen.
- Test all types of APIs: REST, GraphQL, WebSocket, SOAP, JSON RPC, XML, HTTP, and HTTPS.
- Perform all HTTP request methods: GET, POST, PUT, PATCH, DELETE, HEAD, etc.
- Make the API calls with any kind of request data encoding and transfer type like query params, FormData, raw data, etc. Advanced settings allow you to skip TLS, disable redirects, and adjust timeouts.
- Import requests or collections by cURL, link, or file from your device: Swagger, OpenAPI, Postman, and YAML collections are supported.
- Share requests in a second using a deep link and cURL command.
- Powerful GraphQL editor with full-scale experience: body editor with Queries, Mutations, Subscriptions, and syntax support; variables editor, documentation.
- WebSocket testing tool is available too: handles connection and message exchange via WS or WSS.
So you can easily connect with APIs you are working with from everywhere in the world and leave your laptop at home!
