Custom Domain URL Shortener: 5 Free Options Compared

I've been there. You're sharing a link with a potential client, and it's this ugly yourdomain.com/campaign-landing-page-v3-final-updated-2024 nightmare. They're suspicious of the long URL, you can't track clicks, and it looks unprofessional. That's when I realized: a custom domain shortener isn't just nice-to-have—it's essential for credibility.

The problem? Most shortener solutions cost $35-100/month just to put your brand on a link. And they charge you extra for the features you actually need: analytics, API access, QR codes.

I tested 5 free options that let you use your own domain. Here's what I found.

Why Custom Domain Shorteners Matter

Before we dive into the options, let me explain why this actually matters:

• Branding: mycompany.co/deal looks infinitely more professional than bit.ly/xyz123
• Trust: Users click branded links at higher rates because they recognize your domain
• Analytics: You need to know how many people clicked, when, and from where
• Control: Your links don't die if the service shuts down or changes pricing

The wild part? Most free URL shorteners give you zero analytics. They're basically fire-and-forget. You need something that actually gives you data.

The 5 Options

1. Dub.co (The Best Option)

Dub.co is what I switched to after years of Bitly frustration.

What you get free:

• Unlimited custom domains (yes, really)
• Click analytics with location, device, and referrer data
• Full REST API access (not a pro-plan feature)
• QR codes with custom branding
• Team collaboration
• Webhook support for real-time events

Cost: Free tier is genuinely unlimited. Pro starts at $20/month (optional).

Why it wins: Dub.co gives you at the $0 price point what Bitly charges $35/month for. The API access is a game-changer—you can programmatically create links, fetch analytics, or integrate shortening into your app.

Here's a quick API example:

// Create a shortened link with Dub.co
const response = await fetch('https://api.dub.co/links', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${DUB_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    url: 'https://example.com/long-landing-page',
    domain: 'mycompany.co',
    key: 'summer-sale', // custom slug
    expiresAt: new Date(Date.now() + 30 * 24 * 60 * 60 * 1000), // 30 days
  }),
});

const data = await response.json();
console.log(`Short link: https://${data.domain}/${data.key}`);

This is production-grade stuff. The webhook system means you can track conversions in real-time.

2. Short.io

Similar to Dub, but older. Free tier includes:

• 1 custom domain
• Basic analytics
• Limited API

Cost: Free for 1 domain, then ~$19/month for more

The catch: API is limited on free tier. You'll hit walls quickly if you're building anything serious.

3. Rebrandly

Used to be the gold standard. Free tier:

• 1 custom domain
• Basic analytics
• Mobile app

Cost: Free, but pro is $24/month

The problem: Free tier is ancient. No API access, limited features, clunky UI. It's been overshadowed by newer tools.

4. TinyURL (with custom domain)

The classic. Free tier:

• Basic shortening
• Custom domain support
• Simple analytics

Cost: Free, premium is $5/month

Reality check: It works, but it's bare-bones. No API, no advanced features. Fine if you just need to shorten URLs, but not if you're trying to do anything strategic with your data.

5. Bit.ly (Free Tier)

Everyone knows Bit.ly. Free tier:

• Basic link shortening
• Click analytics (limited)
• 1 custom domain option

Cost: Free, but meaningful features start at $35/month

Why you should avoid it: Bit.ly's free tier is a poverty trap. The moment you need decent analytics or API access, they push you to the $35/month plan. That's where I realized Dub.co's free tier actually gives you more.

Feature Comparison

Feature	Dub.co	Short.io	Rebrandly	TinyURL	Bitly
Free Tier	Yes	Yes	Yes	Yes	Yes
Custom Domains	Unlimited	1	1	Limited	1
Analytics	Full	Basic	Basic	Basic	Limited
API Access	Yes	Limited	No	No	No (paid)
QR Codes	Custom branding	Basic	No	Basic	Basic
Webhooks	Yes	No	No	No	No (paid)
Free Forever	Yes	No	No	Yes	No

The gap is real. Dub's free tier honestly rivals competitors' $20-35/month plans.

Real-World API Example

Let me show you why API access matters. Say you're running a marketing campaign and need to track which channel drives conversions:

// Fetch analytics for a link
const analytics = await fetch(
  'https://api.dub.co/links/mycompany.co/summer-sale/analytics',
  {
    headers: { 'Authorization': `Bearer ${DUB_API_KEY}` },
  }
);

const data = await analytics.json();
console.log(`Total clicks: ${data.clicks}`);
console.log(`Top referrer: ${data.top_referrer}`);
console.log(`Conversion rate: ${data.conversion_rate}%`);

With Bit.ly's free tier, you can't do this. You're stuck refreshing a web dashboard. With Dub.co, you can automate your entire analytics pipeline.

The Real Cost Comparison

Let's be specific. If you actually need proper link management:

• Bit.ly Pro: $35/month = $420/year
• Rebrandly Pro: $24/month = $288/year
• Short.io Pro: $19/month = $228/year
• Dub.co: Free forever with better features than their paid competitors

I switched to Dub because the economics are absurd once you do the math. Why pay $35/month for something you get free with more capabilities?

The Catch (Yes, There Is One)

Dub's free tier is genuinely free, but here's what you should know:

• They make money on higher tiers with advanced features (team management, custom integrations)
• Open-source community keeps the core tool honest
• You're not the product—you're a potential customer they want to impress

Compare that to Bit.ly, which limits your free tier specifically to upsell you.

Conclusion: Make the Switch

If you're still using Bit.ly's free tier or debating between options, try Dub.co free. No credit card, no limitations on custom domains, full analytics, full API.

The three things that won me over:

1. Unlimited custom domains on the free plan (game-changer for multi-brand setups)
2. Real API access means you can build with it, not just use it
3. QR code branding so your QR codes match your brand aesthetic

I've been using it for 8 months across 12 projects, and I haven't hit a single limitation on the free tier. Start free, upgrade if you hit team collaboration needs. That's the model that actually makes sense.

Go create your first short link on Dub.co—you'll see what I mean immediately.
