sublink.works

What It Is

Sublink Worker is an open-source “next-generation subscription management hub.” It is not positioned as a proxy/VPN node provider; instead, it is a self-hosted tool that converts existing proxy subscriptions, shared links, or configuration files into client-ready configs for Sing-Box, Clash, Surge, Xray, and others. The text states that it is open-sourced under the MIT License and has already seen 7.2k+ deployments.

Core Capabilities and Proxy Perspective

In terms of proxy types, IP pool size, and country coverage, the page does not provide residential, datacenter, or mobile proxy resources, nor does it disclose any IP pool scale. This indicates that it does not sell routes or nodes, but processes subscriptions supplied by the user. On protocol support, the text says it supports all mainstream protocols and can detect them automatically, while the API output mainly focuses on Sing-Box, Clash, Surge, and Xray configurations. It does not explicitly list HTTP or SOCKS5 proxy sales capabilities. Its rule system is fairly complete, with predefined rules for ads, AI, YouTube, Google, Telegram, streaming, gaming, GitHub, and more, as well as support for custom domains, IP CIDR, protocol matching, and other rule types.

Deployment, Privacy, and Pricing

The project supports deployment on Cloudflare Workers, Node.js, Vercel, Docker, and other environments, and works with storage backends such as KV, Redis, Upstash, and Vercel KV. On privacy, the text states that subscription links are used only during conversion, are not stored or logged, and are processed within the user’s own Worker instance. The project is also open source and auditable. There is no commercial plan information; it is primarily an open-source self-hosted model, so users may need to cover the costs of cloud platforms, KV storage, or server resources themselves.

Pros and Cons

Its strengths include multi-client output, a mature rule system, and API-friendly design, making it suitable for automating subscription conversion workflows. Self-hosting also reduces reliance on third-party conversion sites. The drawbacks are that it does not provide nodes, bandwidth, concurrency, or anonymous proxy resources, so it cannot replace proxy/VPN providers or proxy pool services. In addition, self-deployment and configuring a storage backend still pose some barriers for complete beginners, and short-link or configuration-saving features require users to add their own access tokens or rate limiting.

Who It’s For and Access from China

It is suitable for individual users, developers, and operations teams who already have proxy subscriptions and want to manage Clash, Sing-Box, Surge, and Xray configurations in one place. The text does not state its accessibility from China, so it is marked as unknown. If the official site or demo instance is unstable to access, users can consider deploying it themselves on Cloudflare Worker, Vercel, or Docker, or using alternatives such as Subconverter.
