the blunt take
“A URL shortener is a weekend. Bitly-the-platform — with dynamic QR codes, branded domains, UTM tracking, link-in-bio pages, AI features, and 10 billion monthly clicks worth of infra — is a month of hard choices about what to cut.”
The core redirect table is genuinely trivial. What you're really building is the analytics pipeline, the dynamic QR engine, and the branded domain routing — and each of those is its own project.

or, you know, use one of these.
if building feels spicy
option A
YOURLS (self-host)
Open source, PHP, runs on a $5 VPS. URL shortening done. No QR codes or analytics dashboards, but it's free forever.
option B
Dub.co (open source)
Literally the open-source Bitly clone you were about to build. MIT licensed, Next.js, Prisma, full analytics. Just deploy it.
option C
Linktree free tier
If all you need is link-in-bio, skip the whole build entirely.

01
easy
Slug → redirect table
A Postgres row with a short_code and destination_url. One edge function. You'll be done before lunch.
02
easy
QR code generation
qrcode.react or a headless library. Spit out SVG. Style with CSS. Done.
03
medium
Click analytics pipeline
Log every hit: referrer, user-agent, country (from IP), timestamp. Batch inserts matter at scale. Use ClickHouse or Supabase's pg_partman.
04
medium
Dynamic QR codes (retargetable)
QR points to your redirect slug, not the final URL. You already have this if you built the redirect table right. The tricky part is making this obvious to users in the UI.
05
hard
Branded / custom domain routing
Users bring their own domain. You need wildcard DNS, per-tenant SSL via Cloudflare or cert-manager, and routing logic that maps domains to workspaces. This is the real engineering.
06
nightmare
Redirect latency at scale
10B clicks/month is ~3,800 req/sec average, with massive spikes. Bitly runs edge infra globally. You'll hit Vercel's limits or your DB connection pool before you hit their numbers. Design for this early or redesign painfully later.
