DBGR: HTTP client that gives you full control

PyPI version License Build Status Code Coverage Documentation Status

Dbgr [read 'ˌdiːˈbʌɡər'] is a interactive terminal tool to test and debug HTTP APIs. It offers alternative to Postman, Insomnia and other HTTP clients. It is designed for programmers that prefer to use code instead of graphical tools and want full control over their HTTP requests.


The easiest way to install DBGR is via PyPi:

$ pip install dbgr
$ dbgr -v

DBGR requires Python >=3.6.

Quick Start

First step when working with DBGR is to create a directory which will DBGR search for requests and environment settings.

$ mkdir quickstart
$ cd quickstart

Inside create your default environment file default.ini. For now just place a section header inside:


Now create another file, call it quickstart.py and place create your first request:

from dbgr import request

async def get_example(session):
    await session.get('http://example.com')

You can check that DBGR registered the request by running dbgr list:

$ dbgr list
 - get_example

To execute it, run dbgr request get_example:

> GET http://example.com
> 200 OK
> Request headers:
>  Host: example.com
>  Accept: */*
