About dupes.gg
A marketplace built by an S&Box player for S&Box players.
Why this exists
For years, sharing your best builds in S&Box meant catching someone in the right server at the right time, hoping they wanted what you had, and hoping they had something worth trading back. Hours of work in a sandbox vanished the moment a server wiped or a creator stopped playing.
There was no way to actually be a creator. No way to put a price on the time you spent designing a base, tuning a vehicle, or engineering a working contraption. No way for buyers to find what they wanted without joining random servers and asking around.
What we built
dupes.gg is a real marketplace. Creators upload their .dupe files, set their own prices, and keep 90% of every sale. Buyers browse listings with screenshots, video previews, and verified ratings before spending a cent. Stripe handles the money. Steam handles the identity. We handle everything in between.
Every download is forensically watermarked, every file is validated, and every seller is a real Steam account. The goal is simple: make S&Box creators feel like the work they put in actually matters.
What we believe
- ✓Creators deserve to get paid. The 90/10 split is one of the highest in the modding community for a reason.
- ✓Quality should rise to the top. Verified-purchaser ratings keep the marketplace honest.
- ✓Builds should never disappear. Once a dupe is listed, it's available forever.
- ✓Pirates have nowhere to hide. Encrypted watermarks identify leakers within seconds.

Founder & developer
I spent thousands of hours in Garry's Mod over more than a decade. Building contraptions in sandbox, running roleplay servers, sharing dupes with friends — gmod was a huge part of my life. When S&Box started showing up as the spiritual successor, I was hooked instantly.
dupes.gg is what I wish had existed for the gmod community thirteen years ago. It's the place I want to use myself, built for the next generation of creators.
