What is this?
The LINE store search excludes certain results, specifically when they are region locked, or have a time limit. However, the metadata can always be requested for a sticker, unless it has been deleted. So this website scrapes the LINE store for every sticker's metadata and saves it onto a local sqlite DB.
While all the metadata might be downloaded beforehand, the stickers themselves are downloaded on demand. Stickers with animation or sound will take longer, since they must be merged into a webm file. So if you are the first person to request a sticker, you might have to wait a bit. I also don't leave the scraper running at all times, only running it from time to time, so new stickers might be missing.
