Discord Build Logger
The Discord Build Logger is a service that logs every released build of the Discord client since 2018. It is currently offline pending a rewrite[External Links 1]. It was created by Megumin, and has gone through a number of rewrites since its inception. One day, as always, Megumin will have an ADHD-fuelled programming session and the build logger will be available again.

Features
The Discord Build Logger has a number of features, including some that were not available on any other services at the time of inception.
Experiment Viewer
For any chosen build, you could view all the Discord Experiments that were available in that release. Because of its use of Abstract Syntax Tree parsing[External Links 2], it could pick up experiments that were in the code, even if they were not actively registered in the client.
Module Browser
Using DPacker[External Links 3], another tool written by Megumin, the Discord Build Logger allowed the user to browse every JavaScript file, and the contents of all the individual Webpack Modules in a formatted, easy to read format. It also showed which modules depended upon other modules, allowing you to follow the flow of the code.
Builds Backlog
Build IDs could be provided and the logger could then scrape historic builds as far back as 2018, adding that information to the database. This includes IDs for current, and expired Build Overrides.
API
The Discord Build Logger has a free, undocumented API allowing users to build their own tools or export data from the website.
