Backstairs Game House is a Chrome add-on developed by kakapon.tw. It provides users with easy access to various information and resources related to the Backstairs game. The add-on includes links to Facebook, Youtube, Discord, and other relevant platforms. Users can also find chat room information and access a tool that automatically clicks on "bald points" for additional rewards.

Privacy is a priority for this add-on, as it does not collect any user information. The program is licensed under MIT, and it utilizes several libraries and resources such as jQuery, Bootstrap, Moment.js, tmi.js, arrive.js, and Papa Parse.

The latest update, version 1.0.1, terminated the opening notification service due to changes in the Twitch API v5. The previous version of the API has been deprecated and will be discontinued on February 28, 2022. This is the first version of Backstairs Game House.
