Butterflight Configurator


Butterflight Configurator is a crossplatform configuration tool for the Butterflight flight control system.

It runs as an app within Google Chrome and allows you to configure the Butterflight software running on any supported Butterflight target.

There is also now a standalone version available, since Google Chrome Apps are getting deprecated on platforms that aren't Chrome OS. Downloads are available in Releases.

Various types of aircraft are supported by the tool and by Butterflight, e.g. quadcopters, hexacopters, octocopters and fixed-wing aircraft.


Butterflight Configurator is a fork of Betaflight Configurator which itself is a fork of the Cleanflight Configurator with support for Butterflight instead of Cleanflight.

This configurator is the only configurator with support for Butterflight specific features. It will likely require that you run the latest firmware on the flight controller. If you are experiencing any problems please make sure you are running the latest firmware version.



Download the installer from Releases.

How to use

You can find the Butterflight Configurator icon in your application tab "Apps"

Native app build via NW.js

Linux build is disabled currently because of unmet dependecies with some distros, it can be enabled in the gulpfile.js.


  1. Install node.js
  2. Change to project folder and run npm install.
  3. Run npm start.

App build and release

The tasks are defined in gulpfile.js and can be run either via gulp <task-name> (if the command is in PATH or via ../node_modules/gulp/bin/gulp.js <task-name>:

  1. Optional, install gulp npm install --global gulp-cli.
  2. Run gulp <taskname> [[platform] [platform] ...].

List of possible values of <task-name>:

  • dist copies all the JS and CSS files in the ./dist folder.
  • apps builds the apps in the ./apps folder [1].
  • debug builds debug version of the apps in the ./debug folder [1].
  • release zips up the apps into individual archives in the ./release folder [1].

[1] Running this task on macOS or Linux requires Wine, since it's needed to set the icon for the Windows app (build for specific platform to avoid errors).

Build or release app for one specific platform

To build or release only for one specific platform you can append the plaform after the task-name. If no platform is provided, all the platforms will be done in sequence.

  • MacOS use gulp <task-name> --osx64
  • Linux use gulp <task-name> --linux64
  • Windows use gulp <task-name> --win32

You can also use multiple platforms e.g. gulp <taskname> --osx64 --linux64.


Butterflight Configurator has been translated into several languages. The application will try to detect and use your system language if a translation into this language is available. You can help translating the application into your language.

If you prefer to have the application in English or any other language, you can select your desired language in the options menu of the application.



Make sure Settings -> System -> "User hardware acceleration when available" is checked to achieve the best performance
