Sync Cloud Drive Files to Fast.io for Direct Downloads
Fast.io can automatically sync cloud drive files to its own cloud, using CloudFlare and Akamai for CDN acceleration while providing direct download links. Similar to programs like Oneindex, Fast.io supports multiple cloud drives and requires no self-setup; users can simply register to start using it.

Registering for Fast.io
Fast.io currently supports Google Drive, Box, Dropbox, OneDrive, MediaFile, and GitHub. The registration address is:
- Registration URL: https://go.fast.io/signup/
Using Fast.io
Create a subdomain in the Fast.io backend and select the storage you wish to connect. For example, I created a subdomain https://xiaoz.imfast.io/ and connected it to my OneDrive.

This will generate a folder named Fast.io/xiaoz.imfast.io in your OneDrive. Simply copy or upload your files to this directory, and they will automatically sync to Fast.io's cloud storage.

By visiting the subdomain provided by Fast.io, such as https://xiaoz.imfast.io/, you can view the files inside your OneDrive, as shown below.

The links provided by Fast.io support direct downloads, which is very convenient. Additionally, Fast.io uses CloudFlare and Akamai for CDN acceleration. Using a single-threaded browser download, I achieved speeds of 1.5Mb/s, which is quite good.

Limitations
The free version of Fast.io supports up to 5 sites, with a maximum single file size limit of 500MB and 100GB of monthly traffic. The paid version also supports password protection and larger single files. The pricing plans are shown below.

Summary
Compared to direct link programs like Oneindex, Fast.io supports a wider range of cloud drives and requires no self-setup. However, the free version is limited by single file size and monthly traffic. Ultimately, choose the option that best suits your needs.
Using Fast.io makes it easy to provide direct download links for cloud drives and can even rescue cloud drives that are blocked in certain regions. Fast.io also supports custom domains, so interested users are encouraged to register and explore further.
