Submit Your Game

Publish your browser game on MossGap and reach players worldwide.

MossGap is an open arcade for browser games. Developers can submit their own game and get it featured on the platform. It's free - you only need a registered account.

What you need to prepare

A cover image URL: a horizontal image (1200x630 recommended) hosted on your own server.

A game URL: a public https page that runs your game directly in the browser.

Iframe-ready: your page must work when embedded in an iframe. Do not block framing with X-Frame-Options or CSP frame-ancestors, and make sure it adapts to any width and height.

A category: pick the category that best matches your game.

Please note

File uploads are not supported. You cannot upload a ZIP or game assets - you just provide the two URLs above and host the game yourself.

Moss SDK coming soon

A Moss SDK is on the way, with leaderboards, achievements, saves and analytics. For now iframe embedding is all you need, and games submitted today can opt into the SDK later.
