Downloading Instagram stories without the app requires a few different methods, each with its own set of requirements. one popular method is to use the 'Repost for Instagram' browser extension from the Chrome web store. this extension allows users to save any post, story, or even reels from Instagram and saves them directly to their device.

A second option is to use third-party tools and websites not affiliated with instagram. some websites offer easy-to-use interfaces that can save stories from the platform without needing an account on those websites. these usually offer downloading capabilities for both stories and reels.

However, you should be careful when using third-party tools as they may be as violating instagram's terms of service. only a few of these tools are available anymore and downloading could potentially be halted due to their removal from the web store, and in addition there is a alternative option which is doing instagram story downloads using personal computers or devices with the app "Ins'Eye" which is a dedicated screen recording app. This is an additional method as long as you have the correct system specifications such as having a smartphone with a good processor, good storage space on the device, enough memory and internet speed.

Some people prefer the first three methods mentioned since they do not require downloading any additional apps which users might be hesitant to download something not directly affiliated with the app. Users are always free to access their saved stories from wherever they wish because they are saved on the local device not within an app anymore.

No matter the method that gets chosen, the ability to download anonymous instagram story viewer stories, such as ig story downloader without needing the actual app is very convenient for people looking to download instagram stories to their devices without installing and utilizing a third-party app which could slow down mobile devices.
