Updated

A bio link is set once and clicked for months. Followers tap it long after you've forgotten where it points, so it's the link most likely to end up on a page that's moved, sold out or gone.

Day one

short link
yoursite.com/guide

The link and the page both work.

Page moved

short link
404 Not Found

The link still redirects, to a page that's gone.

Shortener closed

short link
yoursite.com/guide

The page is fine, but nothing sends visitors to it.

One link, three stages
  • The page changes after you post. A launch ends, a product sells out, a sign-up form closes.
  • Nobody checks. A bio link doesn't show an error to you, only to the follower who taps it.
  • Old posts keep sending people. "Link in bio" in a post from last spring still points at today's link.
  • It's checked every 30 minutes. ndle checks the page behind every short link, and flags it on your Monitoring page when it returns a 404, times out or fails its certificate check.
  • You see who taps it. Clicks by day, country, device, referrer and UTM campaign, on the free plan.
  • It can be yours. The free plan includes one custom domain, so your bio can read go.yourbrand.com.
  • No ad page. A tap goes straight to your page.
  • A QR code comes with it, for posters, packaging and business cards that point to the same place.

Instagram lets you add up to five links to your bio, though only the first shows on your profile; the rest sit behind it (TechCrunch). In March 2026 Meta also began testing clickable links in post captions for Meta Verified subscribers (Engadget).

Every one of those links can be an ndle link. Tag each with utm_source=instagram and utm_medium=social using the free UTM builder, and Instagram traffic is easy to spot in ndle and in Google Analytics.

What ndle isn't

ndle isn't a link-in-bio page builder. It doesn't make a page of buttons like Linktree does. It makes the links themselves: short, counted, and checked. Use ndle links directly in your bio, or on whatever bio page you already have.

Questions

Can I use ndle links in my Instagram bio?
Yes. An ndle link works anywhere a web link does: your bio, your other bio links, stories and posts.
Is ndle a Linktree alternative?
Not exactly. ndle doesn't make a page of buttons. It makes short links you can put in your bio or on the bio page you already use, and it checks each one every 30 minutes.
How do I see which clicks came from Instagram?
ndle breaks clicks down by referrer and UTM campaign. Tag the link with utm_source=instagram to make Instagram traffic easy to pick out.
Is ndle free?
Yes. The free plan has 100 active links, 1 custom domain and unlimited QR codes, and every link is checked every 30 minutes. No card needed.
