Sublink Worker is an open-source subscription management and conversion tool designed for individual users. It brings multiple proxy subscription formats into one workflow, automatically recognizing common inputs and generating configurations for Sing-Box, Clash, Surge, and Xray. Users can paste a subscription link or supported configuration, convert it, and copy the resulting output for their preferred client.

The project focuses on straightforward setup and flexible deployment. It can run on Cloudflare Workers, Node.js, Vercel, or Docker, with storage integrations for KV, Redis, Upstash, and Vercel KV. Its configuration storage can manage basic settings and short links, with a default 30-day expiration that can be extended. Sublink Worker also offers preset rule sets, customizable rules, a web interface, and a REST API, supported by documentation covering installation, runtime and storage options, configuration, and troubleshooting. The software is distributed under the MIT License, allowing its code to be inspected. According to the project, subscription links are used during conversion but are not stored or logged, and processing takes place within the user’s Worker instance.
