An addon download manager for World of Warcraft
If you download the addons manually now and you need a fast and easy way to unzip them all into your addons folder, please have a look at WAUZ, a tiny unzip tool for World of Warcraft addons.
WADM is an easy-to-use addon download manager for the popular video game World of Warcraft. WADM is made to simplify downloading of multiple WoW addons from the Curse website. WADM is written in C#, using the classic .NET Framework and is deployed as a WPF GUI application, as well as a command line application. It´s just a simple .exe file, no installation required. WADM exists since a long time (~2011). WADM´s home formerly was found at CodePlex.
This has nothing to do with WADM per se, but Curse (now Overwolf, since a few years) finally implemented some access control in their REST API, by using API keys, to control who is using their API. It´s meant to protect their API from being used by tools that are not the official Curse download client. They also use some Cloudflare anti-scraper security mechanisms, to protect their website. So, scraping the website is also no longer an option, if not using rather complex stuff like "pupeteer" or "selenium" and other scraper tools. And even with the help of such tools you have to constantly fight against the actual website security changes. Many of us just stopped fighting that fight. For more information about this topic and all the „Overwolf problems“, please have a look at the communities of the Ajour and WowUp addon management tools, or use your Google-Fu (to find, in example, some discussions like this). These topics are heavily discussed there, since a good while. Overwolf always mentioned, since years, they want to protect their API, to prevent the usage of other download clients, besides their own. Since they now made that a reality, there is not much we can do at the moment.
