TL;DR. A Reddit link tapped from inside another app opens a logged out web view where joining a subreddit, voting and commenting all require signing in. A deeplink opens the Reddit app on the community or post you are pointing at, where the join button is one tap. Free, with a web fallback.

If you are building a community on Reddit and sending people there from elsewhere, this is where the funnel leaks.

What happens today

Reddit's mobile web experience pushes hard toward the app and shows a constrained view to logged out visitors. Tapped from inside Instagram or TikTok, your link lands in a webview with no Reddit session, so your visitor sees a stripped page, gets prompted to sign in, and often leaves before reaching your community at all.

Joining a subreddit, upvoting or commenting all need an account, and none of them are pleasant inside another app's browser.

What changes with a deeplink

The link opens the Reddit app directly on your subreddit or your post. Your visitor is already signed in, so joining is one tap and the content renders properly. Without the app installed, the link falls back to the web.

Setting it up

1. Copy the URL of your subreddit or the specific post.

2. Paste it into the deeplink generator on OpenUp.

3. Add a readable slug.

4. Use the link wherever you promote the community, bio, Stories, other platforms.

5. Test it from inside the social app on a real phone.

What changes for a visitor

The bottom line

Communities grow when joining is frictionless. A logged out webview is the opposite of frictionless, and it sits between your promotion and your community on every single tap.
