Microsoft 365 add-ins are invisible infrastructure. They power critical workflows in finance, compliance, and collaboration — but there's no central place to look up what an add-in does, how it performs, or whether it's compatible with your environment.
That's what the Vediram Add-in Catalog changes.
What's in the catalog?
Every add-in we discover gets an identity card with:
- Identity: ProgId, publisher, type (COM, VSTO, XLL, or Web)
- Versions: Each unique build tracked by SHA-256 file hash
- Performance: Baseline load times aggregated from anonymous telemetry
- Compatibility: Success rates across Office and OS combinations
How does data get in?
Two sources feed the catalog:
- Deck Free — Our free Windows tray app sends anonymous telemetry (opt-out available). No user identity, no IP logging. Just add-in name, version, and boot performance.
- Deck Pro — Tenant-scoped telemetry also contributes to the catalog as a side effect.
