Sync Your Diamond Dynasty Collection to DiamondOps — Chrome Extension

If you play Diamond Dynasty, you have cards. Hundreds of them. Probably over a thousand. And unless you're the kind of person who maintains a spreadsheet (respect), you have no idea what most of them are worth, which ones you should sell, or which buried gems are sitting in your binder collecting dust.

That's what the DiamondOps Chrome Extension fixes. One click, and your entire Diamond Dynasty inventory is synced to DiamondOps.

The Problem

Diamond Dynasty doesn't give you good tools for managing a large collection. You can scroll through your binder card by card, but there's no way to see your total portfolio value, find cards that have spiked in price, or identify which cards you should sell before a market crash. Manually tracking 1,000+ cards is impossible. Nobody is doing that.

The Solution

The DiamondOps Chrome Extension reads your card inventory directly from mlb26.theshow.com — the official MLB The Show companion site — and pushes it to your DiamondOps account. No manual entry. No spreadsheets. No screenshots.

How It Works

1. Install the extension from the Chrome Web Store
2. Go to mlb26.theshow.com and make sure you're logged into your MLB The Show account
3. Click the DiamondOps extension icon and hit Sync
4. Your full card inventory is pushed to your DiamondOps account within seconds

That's it. Four steps. Run it whenever you want an updated snapshot of your collection — after a pack opening, after making trades, whenever.

What It Unlocks

Once your inventory is in DiamondOps, the platform can do things that are impossible without it:

• Portfolio tracking — see the total value of your collection over time, broken down by series, overall rating, and position. Know exactly what your binder is worth.
• Buried gems discovery — DiamondOps finds cards in your collection that have increased in value since you acquired them. Cards you forgot about that are now worth selling.
• Inventory-based lineup optimizer — build lineups from cards you actually own, not just cards on the market. The optimizer knows what's in your binder.
• Sell analysis — identify cards that are at their peak value and likely to drop, so you can sell before the market moves.

Chrome Only (For Now)

The extension is available on Chrome only. It works in any Chromium-based browser (Chrome, Edge, Brave, Arc), but not Safari or Firefox. Safari and Firefox support may come in the future, but Chrome is the priority right now because that's where the majority of users are.

Privacy

The extension does not scrape anything automatically. It only runs when you click the Sync button — you control when it activates. No background processes, no scheduled scraping, no automated requests to The Show's servers.

Your inventory data is pushed directly to your DiamondOps account and stays there. It's not shared, sold, or used for anything other than powering your personal DiamondOps features. Read the full Privacy Policy for details.

Free During Early Access

The Chrome Extension is free for all users during DiamondOps Early Access. After EA ends, inventory sync will require a Pro subscription ($39.99/year) or higher. If you want to lock in founder pricing, sign up during Early Access at diamondops.gg.
