DiamondOps Platform

DiamondOps

The Diamond Dynasty Intelligence Suite

DiamondOps combines lineup building, market intelligence, and collection management into one platform — available as an iOS companion app and a full-featured website at diamondops.gg. Your synced Diamond Dynasty collection, live market data, and Pro entitlements all live here — everything stays current without you doing anything twice.

Node.js TypeScript MongoDB Express

DiamondOps Chrome Extension Chrome Only · Chrome Web Store →

The sync bridge between your browser and your iPhone apps. Install it once in Google Chrome, run it on the Diamond Dynasty website, and your full card inventory is pushed to the backend — no manual entry, no spreadsheets. Not compatible with Safari, Firefox, or other browsers at this time — additional browser support may come in the future.

  • Required for DiamondOps Pro — inventory sync, ranked lineup builder, Portfolio View & Buried Gems
  • One-click sync keeps your collection snapshot up to date
  • No automated account access — you run it, you control it

Launch Timeline

Now Early Access — diamondops.gg is live with lineup tools, market data, and collection tracking. Free for all users — Pro features included.
Coming Soon DiamondOps iOS companion app on the App Store — full mobile experience for lineup building, flipping, and Diamond Radar on the go

Beta Testing Program

Applications Open
Window closes when seats fill — may reopen in the future

Help shape current and future RetroGhostLabs apps before they hit the App Store.
Applying does not guarantee a spot. Seats are limited and testers are hand-selected. If you're chosen, we'll reach out with next steps.

Very Limited Spots Available

What You Get

  • Free 1-year Pro subscription — awarded after your app has shipped publicly and your feedback has been submitted. One year per app beta tested.
  • Early access to future apps — beta testers get first look at everything coming from RetroGhostLabs
  • Direct line to the dev — your feedback goes straight to the person building the app
  • Priority consideration for future closed betas

What We Need from You

  • Genuine, constructive feedback — bugs, UX friction, missing features, anything that felt off
  • Install updates when new builds drop via TestFlight
  • Submit feedback within the testing window (typically 2–3 weeks per build)
  • Pro reward requires written feedback — no feedback, no Pro unlock

Device Requirements

  • iPhone or iPad — both are supported
  • iOS / iPadOS 17.0 or later required
  • Apple ID — required for TestFlight and Sign in with Apple
  • TestFlight app — free from the App Store; this is how Apple distributes all betas
  • Stable internet connection for market data and inventory sync

TestFlight — How It Works

  • You apply via email — we send you a TestFlight invite link
  • Open the link on your device, accept the invite in the TestFlight app
  • By accepting, you agree to Apple's TestFlight Beta Software License Agreement
  • Beta builds expire after 90 days per Apple's TestFlight policy — active builds are updated before expiry
  • You may receive multiple builds throughout the testing period as we push fixes and new features

About Your Beta Data & Email Communications

  • Data you generate during the beta — collection syncs, market interactions, lineup saves, app usage patterns — is used to test, debug, and improve the app prior to public release.
  • This data is handled in accordance with our Privacy Policy. No data is sold or shared with third parties.
  • Beta data may not persist to the public release version. We'll give advance notice before any reset, but treat this as a testing environment — not permanent storage.
  • By applying, you agree to receive emails from RetroGhostLabs about beta program updates, new app testing opportunities, and program-related announcements. We won't spam you — emails are sent only when there's something relevant to test or share.
  • You can opt out at any time. Every email we send includes an unsubscribe link. Opting out removes you from future beta communications but does not affect any active TestFlight access you already have.
Beta Disclosure & Terms Summary These apps are pre-release software. They may contain bugs, incomplete features, and behavior that changes between builds. Submitting an application does not guarantee selection — testers are hand-picked and not all applicants will receive access. If selected, you will be contacted via the email address you applied with. Participation in the beta program does not guarantee that all tested features will ship in the final version. RetroGhostLabs reserves the right to revoke beta access at any time and to open or close the application window without notice. The free Pro subscription reward is granted at RetroGhostLabs' discretion upon verification of submitted feedback after the app ships publicly — it is not guaranteed and is contingent on genuine participation. Beta testers agree not to publicly share screenshots, video, or details of unreleased features without prior written permission. By submitting an application you consent to receiving email communications from RetroGhostLabs related to the beta program and future testing opportunities; you may opt out at any time via the unsubscribe link included in every email. DiamondOps is an independent product and is not affiliated with, endorsed by, or connected to Sony Interactive Entertainment or Major League Baseball. MLB The Show is a registered trademark of Sony Interactive Entertainment LLC.

Apply for Beta Access

Not all applicants will be selected. If chosen, we'll contact you with everything you need to get started on TestFlight.

The Chrome extension is a sync plugin only — it is not a website. It requires Google Chrome to run on the MLB The Show site.

Your email address is never exposed publicly. Applications are processed privately by RetroGhostLabs.

Applications Are Currently Closed

All available beta seats have been filled for this round. We may open applications again in the future — keep an eye on this page or follow us on YouTube for updates.

If you previously applied and haven't heard back, we'll be in touch before the TestFlight window opens.
