A link in an Instagram or TikTok bio opens inside the app's own browser — signed out, no subscribe button, no autoplay. 301.so hands the tap back to the operating system, so a YouTube link opens in YouTube.

The tap starts inside Instagram's built-in browser.
A webview never honours a universal link on direct navigation. That case gets one tap; every other case redirects straight through.

The real app. The subscribe button works, because the session is there.
iOS gets the app's own URL scheme. Android gets an intent:// with a browser fallback baked in, so a missing app degrades silently instead of erroring. Anything the recipes don't recognise is a plain redirect — never a worse link than the one you started with.
One slug per channel and you stop guessing which bio does the work. Every click records those dimensions off the response path, so measurement never costs the redirect a millisecond. Daily totals per link are kept for good; the dimensions roll on a three-month window.
There is no dashboard you have to click through. A link is one POST, and the slug, the redirect status and the UTM parameters appended to the destination are all yours to set.
