Built lean, built fast. j4h1n0 strips away the bloat and gives you a shortener that just works.
Create short links in under a second. Firebase Firestore handles reads and writes at global scale with near-zero latency.
Name your links anything — /?u=my-brand. Real-time availability checking so you always know what's free.
No email. No password. No OAuth dance. Open the app and start shortening in 3 seconds flat. Privacy by design.
All your shortened links saved locally in your browser. Copy any past link in one click, anytime you revisit.
Every redirect automatically increments a click counter in Firestore. Know exactly how many people visited your link.
Fully responsive for mobile, tablet, and desktop. iOS, Android, any browser — your links work everywhere, always.
No tutorial needed. If you can paste a URL, you can use j4h1n0.
Drop any long URL — social posts, docs, articles, checkout pages. j4h1n0 accepts anything starting with http:// or https://.
Type a memorable alias like my-brand or promo2025. Availability is checked live as you type. Or skip it and we'll generate one.
Hit the button. Your short link appears instantly. One tap to copy it. Your link history is saved locally for later access.
A step-by-step walkthrough of every feature — from pasting a URL to tracking clicks.
Visit j4h1n0.web.app and paste any URL into the big input field. The URL must start with https:// or http://. No registration, no waiting.
Below the URL field, type your desired alias — e.g. my-portfolio. j4h1n0 checks availability in real time as you type. Green means it's yours. Red means it's taken.
Click Create Short Link. Within milliseconds, your short URL is created in Firebase and displayed on screen. If you skipped the alias, a random 3-character code is assigned.
Tap the Copy button next to your new link. The link is copied to clipboard and ready to paste anywhere — Twitter, WhatsApp, email, or wherever you need it.
Every time someone visits your short link, Firebase increments a click counter automatically. You can view the current click count directly in the "Your Links" panel accessible from the top-right button.
All links you've created in this browser are saved locally. Open the Your Links panel to see past creations, their original destinations, and one-click copy buttons.

click count only · no personal trackingThe alias field shows a red indicator and "taken" badge as soon as you stop typing. The Create button won't proceed until you pick an available alias — or clear the field to get an auto-generated code instead.
live availability check · instant feedbackCurrently, j4h1n0 does not have a delete feature in the UI — links are stored permanently. If you need a link removed for any reason, you can contact the developer directly. A delete feature may be added in a future update.
coming soon: delete featureNot currently — destination URLs are fixed at creation time. To redirect to a new URL, you'd need to create a new short link with a different alias. Editing functionality is on the development roadmap.
