This site was made to archive all CASC builds of a specific set of Blizzard applications that have been/are available on their CDN. Builds often get removed from the official CDNs when they're no longer used. This project aims to save those builds and their data.
Issues with this site (or feature requests) should be reported on GitHub (when public) or Discord (invite link is in menu). The code that powers this site is also planned to be pushed to that repository GitHub when I've cleaned it up sufficiently.

For World of Warcraft

For WoW, there's several additional tools available as well.

Files page

The files page has a list of all the files in the game's archives for all known versions that use CASC (everything since 6.0). Previews for some of these files (blp textures, ogg/mp3 sound files, wmo models) are available by clicking on the icon. You can view more information of a specific file by clicking . Files with unknown filenames are colored red in the filename column, if you know/want to guess a filename for this file you can do so by going here. The tool powering previews (and more) for this page can be found on GitHub.

DBC viewer

For browsing WoW's database files you can use the DBC viewer. Using WoWDBDefs definitions any updated DBCs should work shortly after they're released. Keep in mind that if Blizzard updates the DBC format, it will break. The tool providing the data can be found on GitHub.

Diff tool

Allows you to compare two builds of WoW to see which files got added, changed or removed.

Current WoW versions per branch

Hey WoW classic fans, thanks for visiting. Just want to remind you that this isn't an official site! I manually added the WoW Classic Beta to the above list after Blizzard published a new product called "wow_classic_beta". Considering it is on the not encrypted part of the CDN (tpr/wow) it is likely this product will be intended for people outside of Blizzard. Keep in mind there's basically nothing confirmed yet outside of this rather empty reference so things can still change. There are currently no WoW Classic builds available at the time of writing that are newer than the build (and its hotfix) that were demo'd at BlizzCon. It could be hours, days or weeks before anything appears.
Also, the wow_classic changes in the History tab are not at all related to WoW classic. Like all other public WoW products, if one of them updates they all get a cdnconfig update. I won't bore you with the details but you can ignore everything that isn't a buildconfig change.
Build is out.

Table explanation

Table rows/columns with a red background indicate something for that build, buildconfig or cdnconfig is missing. Hashes with a red background mean that that hash itself is missing. You can always click "Show details" to see what exactly is missing.
