Live preview · updates as you type
Your #name, painted with stars.
Every #portal you mint is born somewhere, at some moment. Preview yours below — drop a place, drop a date, watch the renderer paint the exact night sky for that spot. When you claim a #name and mint the portal, that sky becomes the portal's permanent cover art, scannable back to the live page.
Free with every #portal. Generated the moment you mint, locked to your lat/lng + creation timestamp, yours forever.
Featured moments
Tap a moment to try it.
These are real coordinates, real dates, real night skies. Click any card and the configurator above hydrates with that exact moment so you can see how the renderer feels with different times, latitudes, and styles.
How it works
Designing a star map IS designing a #portal.
The three inputs that build your star map — a name, a place, and a moment — are the same three inputs that mint a #portal on hashtag.org. Drop a portal and the star map for the moment of its minting becomes its cover for free, forever.
Pick your #name
Any single word that means something to you. We check availability live during checkout.
Drop your place
A city, a coffee shop, the cliff where you proposed. We geocode it to exact coordinates.
Lock in the moment
The second you click mint becomes the timestamp baked into your portal AND its star-map cover.
Every #portal you mint ships with a free star map.
Use the configurator above to preview what your portal's cover art will look like. Happy with it? Claim your #name and we generate it at the second you mint, deterministically tied to the lat/lng you pinned and the timestamp of creation. No one else will ever have the same sky.
Why every #portal gets one.
When you mint a #portal, we generate the exact night sky above its coordinates at the second of creation. That image becomes the portal's default cover art forever — no swap, no expiry, no extra fee.
Each star map carries a scannable QR linking back to the live portal it represents. Share the image anywhere; whoever scans it lands on your portal page on hashtag.org.
First kiss. Engagement. The day she was born. The moment you opened your business. Drop the place, drop the moment, pick a style — your portal's cover art writes itself.
