URL shortening and link management service for creating concise, trackable links with analytics
Url-Shorten-Worker
Fast, serverless URL shortener powered by Cloudflare Workers
A lightweight, edge‑deployed URL shortener using Cloudflare Workers and KV, offering custom aliases, password protection, link deletion, and cache control—all under an MIT license.
Overview
Overview
Url-Shorten-Worker delivers a minimalist URL shortening service that runs entirely at the edge on Cloudflare Workers. By leveraging Workers KV for persistence, the service provides sub‑second redirects without managing any servers.
Capabilities
The platform supports user‑defined aliases, optional password protection, and per‑link cache‑control settings. A built‑in interface lets you delete individual entries, and the client stores recent URLs in localStorage for quick reuse. All data resides in a KV namespace bound to the worker, ensuring durability across deployments.
Deployment
To launch your own instance, create a KV namespace in the Cloudflare dashboard, bind it to the worker under the variable name LINKS, copy the provided index.js into a new Worker, and click Save and Deploy. The demo site expires links after 24 hours, so for production use you should host your own version. The project is released under the MIT license and is ready for immediate customization.
