I Built a Free In-Browser API Tester — No Postman Install Needed

Source: Dev.to

Introduction

We’ve all been there—you just need to fire a quick API request, but you end up:

• Booting up Postman (and waiting for that Electron app to load 🐢)
• Installing a VS Code extension just for this
• Trying to remember the exact curl syntax you always forget

I got tired of it, so I built a lightweight API Request Generator & Tester.

Features

• Choose your HTTP method (GET, POST, PUT, DELETE, PATCH)
• Set custom headers
• Pass a request body (JSON, form data)
• Inspect the response – status, headers, body
• Zero install. Zero sign‑up. Just open and use.

Usage

The tool works entirely in the browser. Open the URL, select your method, add headers or a body as needed, and hit Send to see the response instantly.
