A random back-half like /a9Kf2Q tells a reader nothing. A custom slug turns the same link into /spring-sale: readable, on-brand, and easy to trust. You type the ending you want in the create form, Flyn checks that it is available and not a reserved word, and you get a clean link that looks intentional. Custom slugs are free on every plan, including Free, with no cap on how many you can name. This page covers the back-half of the link; using your own domain instead of flyn.to is a separate feature (branded short links) that pairs perfectly with a custom slug.
How to Create a Custom Short Link
Watch on YouTubeTranscript
A random short link tells people nothing. flyn.co/our-song tells them what it's about. Step one. Click Create Link in the sidebar, then paste the link you want to share into Destination URL.
Step two. In the Short Link row, type a name for your link in the box after flyn.co. Use plain letters, numbers, hyphens and underscores. The line underneath shows how your link will look.
Step three. Click Create Link. That's when Flyn checks the name, so let me show you what it catches. Each name exists only once on flyn.co, across every account, and our-wedding is already taken. So pick another. Spaces aren't allowed either, so our song with a space is caught too. Some common words, like pricing or events, are reserved as well. Use a hyphen, and click Create Link again.
And there it is: flyn.co/our-song. Copy it, or scan the QR code underneath to test it. To print it, download the code from the link's details. One tip: the name is case-sensitive. Our-song with a capital O would be a different link, so keep your names lowercase.
Can you rename it later? Yes, under Custom Slug in the link's details. But the old link, and any QR code you've printed, stop working at once, and someone else can claim the old name. So pick your name before you share it. To send people somewhere new, change the Destination URL instead.
Naming your links is free on every plan. The Free plan gives you 25 links a month. Pro, at $12 a month, or $9 a month billed annually, removes that limit and lets you use your own domain instead of flyn.co. The written steps are linked in the description.
How it works
Up and running in minutes
Type the ending you want
When you create a link, enter your desired slug in the custom slug field, like spring-sale or 2025-menu. Use lowercase letters, numbers, and hyphens for the cleanest result.
Flyn checks it instantly
Flyn confirms the slug is available and not a reserved word before you save. If it is taken, you will know right away and can pick another, so you never publish a broken or duplicate link.
Share your named link
You get a short link ending in exactly what you chose, ready to paste, print, or say out loud. The destination stays editable, so you can repoint the same slug later without reprinting anything.
Why it matters
What you get
Memorable and on-brand
A slug like /spring-sale reads like a headline, not a serial number. Your links match your campaign names and look like they belong to you.
More trust, more clicks
People click links they can read. A clear, descriptive slug signals where the link goes, which lifts confidence and click-through versus a random string.
Easy to say and to print
Custom slugs are short enough to read aloud on a podcast, put on a flyer, or dictate over the phone. No spelling out random characters.
Pairs with a custom domain
Add your own domain (a separate feature) and your slug becomes part of a fully branded URL, so the whole link, front and back, is yours.
Editable destination, stable slug
Every Flyn link is editable. Keep the same named slug live and change where it points anytime, even after it is printed or shared.
Clean by default
Availability and reserved-word checks stop duplicate or conflicting slugs before they go live, and every click is bot-filtered so your analytics stay honest.

Frequently asked questions
What exactly is a custom slug?
It is the back-half of your short link: the part after the slash, like the spring-sale in flyn.to/spring-sale. Instead of a random string, you choose a word or phrase that describes the link.
Is this really free?
Yes. Custom slugs are included on every plan, including Free, with no separate charge and no limit on how many links you can name.
How is this different from a branded short link?
A custom slug is the back-half of the link. A branded short link uses your own domain in place of flyn.to. They are separate features that work great together: your domain plus your slug gives you a fully branded URL.
What characters can I use in a slug?
Use lowercase letters, numbers, and hyphens for the cleanest, most shareable result. Flyn checks each slug against reserved words and existing links so you never publish a conflict.
What happens if my slug is already taken?
Flyn tells you the moment you enter it, before you save, so you can pick a different ending. Each slug on a given domain has to be unique.
Can I change where a custom slug points after I share it?
Yes. Every Flyn link is editable, so you can keep the same slug live and repoint it to a new destination anytime, which is handy for reused campaign links or printed materials.
