We turn flat photos
into rooms you can
walk through.

Galerra is a 3D virtual gallery platform for visual artists, photographers, illustrators and small institutions. Upload your work, pick a room template, share a link — visitors walk through your gallery in their browser, click each piece for details, and inquire about buying directly from you.

No 3D modelling, no downloads, no headset required. Everything runs in a normal browser on phone or desktop.

Why this exists

The standard way artists show work online is a grid of thumbnails on a website nobody visits. Galleries cost money, take time, and reach only the few people who walk by. Galerra exists because there's a third option: give every artist a real exhibition space — at the cost of a coffee per month — that anyone in the world can step into.

Built solo

Galerra is built and maintained by Michalis Apostolis, a solo developer based in Greece. That means every feature, fix and design choice goes through one person. It also means feedback gets listened to — there's no committee.

How we make money

Free: 1 gallery with 5 works, buyer inquiries — forever free. More works: €10 to unlock one gallery, paid once and never expiring — up to 50 works on it, with AI curation, full visitor analytics and no Galerra branding. Membership: €6.99 a month keeps up to 10 galleries open while you're subscribed. Educator plan: paid classrooms hold up to 150 students.

We don't sell your data, run ads, or take a cut of any sales you make through inquiries. Gallery unlocks, the monthly membership and education plans are the entire business.
