Instagram Post Download Website

I need a website that allow people to download Instagram posts. I have a prototype made with "instaloader" with Django, but I'm running into issues on production, probably Instgram related. I noticed a lot of the top websites are almost identical so I'm wondering if they also just work the same. I'm either looking for someone do it from scratch or fix the existing code/find a solution.

Example websites are:
https://iqsaved.com/
https://snapinsta.app/
https://fastdl.app/en
https://toolzu.com/downloader/instagram/video/
