Which Substack links can LinkStack open?

LinkStack supports Posts on Substack publication domains, Profiles and Notes on substack.com, and Post shares on open.substack.com and on.substack.com. Paste the original public URL and LinkStack keeps that page available as the fallback.

What happens if Substack is not installed?

The visitor can continue to the original Substack web page. The public LinkStack URL still works, so you do not need a separate desktop or fallback link.

Does the same deep link work on desktop?

Yes. Desktop visitors continue to the original Substack page while supported mobile devices can try the app-first path.

What happens after the tap

01
Recognize the destination
LinkStack recognizes the supported Substack URL and keeps the original page intact.
02
Try the app-first route
On a supported mobile device, the click can move into Substack instead of stopping at mobile web.
03
Keep the fallback ready
If the app handoff is unavailable—or the visitor is on desktop—the original Substack page is still there.

Where Substack deep links help

New posts

Share your latest post from a bio, newsletter, or message with a route into Substack.

Reader conversations

Link to a specific Note so readers can pick up the conversation in Substack.

Profile sharing

Send readers to your Substack handle or profile without substituting a publication homepage.

Sharing this link inside a social app?

TikTok, Instagram, Facebook, and Threads can trap clicks in built-in browsers. LinkStack can show a recovery step before normal routing, app handoff, attribution, and analytics continue.
