Roblox Game Passes vs Developer Products (and How DevEx Works)

Most Roblox games make money from two things: passes and developer products. They sound alike but work differently.

The difference in one line

• A pass is bought once and owned forever: VIP, a special area, a permanent power-up.
• A developer product can be bought again and again: currency, potions, revives, temporary boosts.

That's straight from Roblox's docs on passes and developer products.

What changes in your scripts

• Passes: Roblox remembers who owns them. Your script checks whether the player owns the pass when they join and turns the perk on.
• Developer products: your game has to deliver the item itself, with a server script using MarketplaceService.ProcessReceipt that grants the item, saves it, and only then confirms the purchase. Get this wrong and players pay without getting their stuff.

Roblox also offers price optimization, which tests prices for you once your game has enough sales: price optimization docs.

Turning Robux into money: DevEx

The Developer Exchange (DevEx) program swaps Earned Robux for real money. From Roblox's DevEx page:

• The standard rate is 0.0038 USD per Earned Robux, so 30,000 Robux comes out to $114.
• Some purchases from U.S. players verified as 18+ earn a higher rate.
• You need to be at least 13, have at least 30,000 Earned Robux, a verified email, and a tax form on file.

Only Earned Robux count: sales in your game, private servers, Creator Store sales and Creator Rewards. Bought or gifted Robux don't.

What to actually sell

Knowing the tools is the easy part. What to sell, when to offer it and how to price it without hurting retention is what decides how much a game earns. That's the Make Robux module in the Larpings course. See Larpings.
