APIBench: Test REST APIs from Your Android Phone

Postman is great when you're at your desk. But when you're away from your laptop and need to fire a quick API request — check a webhook, test an endpoint, verify that a deployment went correctly — you need something on your phone. APIBench is that tool.

Build and Send HTTP Requests

APIBench is a full-featured mobile REST API client. You can construct any HTTP request: choose the method (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS), set the URL, add headers, and write a JSON or form body. Everything you'd do in a desktop API client, on your phone, with an interface designed for touch.

Headers are easy to add and toggle. The request body editor handles JSON with basic formatting. Auth headers — Bearer tokens, API keys, Basic auth — are straightforward to set up.

View Formatted Responses

Raw JSON responses are hard to read, especially on a small screen. APIBench formats and colour-codes JSON responses so you can navigate the structure without it being a wall of text. Status codes are prominently displayed with their meaning, and response headers are accessible in a separate tab. Response time is shown so you can get a rough sense of API performance.

Save Requests and Build Collections

The requests you run regularly shouldn't have to be rebuilt from scratch each time. APIBench lets you save requests with names and organise them into collections — similar to how Postman handles request management, but designed for a mobile-first workflow. Pull up your saved staging environment endpoints, your auth token exchange requests, or your monitoring calls instantly.

Who Uses APIBench?

Backend developers who want to test an endpoint quickly without switching to their laptop. DevOps engineers verifying that a newly deployed service responds correctly. API consumers who want to check that an external API is behaving as documented. QA testers doing spot checks. Anyone who's ever wished they could run a curl command from their phone without fighting with a terminal app will find APIBench a natural fit.

APIBench is free on Google Play. Search for APIBench and start testing APIs wherever you are.
