Depot screenshot

Depot is your object-store dashboard — a file browser that lets QA, developers, and analysts verify uploads without touching credentials. Grid and list views, in-drawer image preview, signed URLs with 1-hour expiry, and per-environment permissions (download/rename/delete toggles). Breadcrumb navigation, type-specific icons, and rich metadata make it feel like a desktop file explorer.
