So You've used Kodi a fair bit and generally you sticked with the standard Kodi addons setup for watching TV like Incursion/Gaia/Neptune Rising/Placenta/etc. If you digged further you probably saw this RealDebrid and Premiumize mentioned alot and how those debrid services offer better quality streams.
What those services do?
They're an aggregator service that makes you have access to multiple file lockers with one account otherwise you'd have to purchase an account for each file locker. The file lockers fight against them but for the last years those 2 services are constantly winning the battles. One of the best services they offer is the access to cached torrents through add-ons like Gaia add-on which are faster and better than cyber locker links.
You probably landed to a website like Rapigator, Openload, etc and they have files that are hosted on them. If you want to download that file for free you usually have to wait an hour for it to download and even then there is usually a limit on how many GBs you can download in a day. Well if you paid for the premium version these restrictions are removed.
How they do it?
These two sites basically pay for passwords in bulk to file sharing sites like Openload/Rapidgator, etc. to bypass the wait times, file restrictions, and speed restrictions. You then pay a monthly fee to access Real Debrid or Premiumize and they do the heavy lifting for you in terms of the bypassing.
Download fast is important because usually the free tier on file hoster sites is slower than the amount of bandwidth required to watch a SD show without buffering.
It has the effect of buying you a password to many file sharing sites for a fraction of the cost.
What are their main uses?
- Allow you to bypass these restrictions when you go to download any type of file at these sites;
- Allow you to paste a torrent magnet link and convert it to a direct download; and
- Allow you to bypass file sharing site restrictions as mentioned above, but for videos specifically.
- Allows you to get max video download or streaming speed through Kodi addons without a wait time or entering a captcha.
