CF-Workers-SUB

CF-Workers-SUB is a JavaScript tool that runs on Cloudflare's serverless platform (either Workers or Pages). It takes multiple proxy server configurations and subscription links that you provide, and combines them into a single subscription URL that proxy clients like Clash or V2Ray can import. Instead of managing several separate subscription links, you maintain one private URL that always returns your current merged node list.

The tool accepts individual proxy node links in formats like VLESS and VMess, as well as links to external subscription lists from other services. All of these are merged and served from a URL that only you know, reducing the risk of your subscription address being discovered or shared without permission. The README notes that when aggregating a very large number of nodes, Clash clients may time out during the conversion step, so users are advised to trim the node count if this happens.

A notable feature is automatic format conversion. Different proxy clients expect different subscription formats, and CF-Workers-SUB calls an external conversion service to translate the merged output into whichever format a client requests. This lets a single subscription URL work across multiple different proxy applications.

Deployment can be done through Cloudflare Pages by forking the repository and connecting it to the Cloudflare Pages dashboard, or through a Cloudflare Worker by pasting the worker script directly into the Cloudflare editor. Both require a free Cloudflare account. Node links and subscription URLs are stored and managed through a Cloudflare KV namespace, edited via a simple web interface served by the worker itself.
