Exhibit Your Art in a Virtual Museum — Free
Your work, in a museum, tonight. Build a walkable 3D gallery in your browser and open it beside 790,000+ artworks from seven world museums — free, with no commission, and everyone who opens your link walks in together.
Your work, your rights
Upload images, 3D models, and audio. You keep every right to your work and choose the license it carries — Artheon takes a non-exclusive display license and nothing more.
Build a 3D gallery in your browser
A walkable, three-dimensional gallery you assemble right in the browser — nothing to install. Place your works, walk the room as a visitor would, and adjust until it feels like an opening.
Publish beside 790,000+ artworks
Your gallery opens inside Artheon Museum, next to a collection from seven world museums — the Met, Rijksmuseum, National Gallery of Art, Art Institute of Chicago, Belvedere, Smithsonian, and Cleveland Museum of Art — and beside the community of artists already exhibiting here.
Private drafts first
Keep a gallery in draft while you work, and share it with selected people — a mentor, a fellow artist, a friend — before you publish it to everyone.
Every gallery link is a shared room
Share one link and everyone who opens it walks the gallery with you — as avatars, with voice and chat, no account needed to visit. Invite people for an evening and greet them in the room as they arrive: a real opening night, held wherever your visitors happen to live.
Free to exhibit. No commission.
Online exhibition tools charge a monthly fee for an empty room and leave you to find the visitors. Marketplaces take 40-50% of every sale. Artheon charges neither: exhibiting is free and there is no commission, because Artheon sells nothing on your behalf. Your work stays yours to sell, license, or keep — anywhere you choose.
Human-made art only
Artheon exhibits human work. AI-generated images presented as artworks are not accepted, and every upload carries a human-made attestation. Read the AI policy or the human-made page for the full picture.
Coming from Spatial?
Spatial discontinued its Free and Pro 3D worlds on July 27, 2026, and creator spaces were deleted with them. If your gallery was one of them, you can rebuild it here: a walkable 3D space you assemble in the browser, free, with multiplayer included on every link and a public audience built in.
Rebuild your galleryFrequently asked questions
Is it really free?
Yes. Artheon is free for visitors and free for artists — uploading work, building a gallery, and publishing it cost nothing. The platform may add optional paid private or branded spaces later, but exhibiting stays free.
Who owns my work?
You do. You keep all rights and choose the license your work carries; Artheon receives only a non-exclusive license to display what you upload. The details are in the terms.
What about AI-generated art?
AI-generated images presented as artworks are not accepted. Every upload carries a human-made attestation — see the AI policy and our human-made page.
What file formats can I upload?
Images up to 100MB, GLB 3D models up to 100MB, and audio up to 20MB.
Can people visit my gallery together?
Yes. Every gallery URL is a shared multiplayer room: everyone who opens the link walks the space together as avatars, with voice and chat. Visitors don't need an account.
How do I start?
Sign in, then upload your works or head to Galleries to build a space. Arrange your works, walk the room, then publish and share your link.
