The Roblox Client Tracker is an unofficial change tracker which aims to provide detailed difflogs for changes to Roblox's engine. It generates information by datamining builds of Roblox Studio retrieved from their CDN, using various publicly discovered developer channels of Roblox. The data that is analyzed and presented in this repository is generated using publicly reverse engineered Roblox protocols and file formats.

This is dead again because Roblox sucks.

Use these links to compare development builds of Roblox Studio:

• Compare [roblox->zCanary]
• Compare [roblox->zIntegration]

This is a JSON version of Roblox's API Dump. It contains more data than the original API Dump and can be read into a data tree by most programming languages using a JSON parser. This file is extracted using:
RobloxStudioBeta.exe -API API-Dump.json

This is a more "complete" version of the normal JSON API Dump. It includes all classes and enums omitted from the normal dump, and includes a few other notable differences and keys, like Default values on some properties. This file can be extracted with, similarly to -API:
RobloxStudioBeta.exe -FullAPI Full-API-Dump.json

A readable version of Roblox's JSON API Dump. This file is generated from the Roblox API Dump Tool.

A file used by Roblox Studio to provide auto completion for the types built into Roblox's Lua implementation.

A sorted list of undecorated C++ symbol names that could be extracted from the exe.

A sorted list of dumped strings from Roblox Studio's exe. There is some garbage data dumped into this file, but most of it should be legible.

A file used by Roblox Studio which defines the specifications, platforms, and images for all default emulation devices.

A sorted list of fast variables, which are used by Roblox to toggle changes to the engine remotely on multiple platforms without having to redeploy the client.

This CSV maps all of Roblox's known shaders, and which graphics APIs use them. Each mapped shader has a mapped name and shader-type.

A file that describes (almost) every file that is expected to be extracted from the zip files specified in rbxPkgManifest.txt Every two lines of this file corresponds to a local file path, and the MD5 checksum expected of the file extracted to that path.
