Deep Dive: Switching from Bitly to Sink

Trade-offs, installation & data architecture

The Catch vs Bitly

What you trade away

Sink is elegant on Cloudflare, but it lacks Bitly's mature QR campaign management, team permissions, branded-link governance, integrations, and vendor support.

Installation

How to deploy Sink

Fork the repository and deploy a Cloudflare Worker with D1 and KV bindings; Analytics Engine, R2 and Workers AI are optional

Day-2 Operations & Setup

What it takes to run

A non-expert must create and wire several Cloudflare resources, copy binding IDs, set a stable site token and understand build-time versus runtime secrets.

Data Ownership

Where your data lives

The user's Cloudflare account holds links in D1, redirect cache in Workers KV, visit events in Analytics Engine and optional JSON snapshots or social images in R2; the public demo uses the maintainer's Cloudflare account.

Build vs Fork Verdict: YES (the core loop fits in a weekend)

Why fork Sink instead of vibe-coding a Bitly clone?

A slug, a lookup, a 302, and a row in a table. Cloudflare Workers plus KV and D1 does the whole job on the free tier, and QR codes are one library call. The only thing you are really buying is that bit.ly resolves links created in 2012 and will presumably still resolve them in 2032, which is an institutional promise rather than a technical one. If the links are going in a magazine ad or on packaging, that promise is worth something. If they are going in this week's newsletter, it is worth nothing, and Growth is 420 USD a year.
