A glanceable watchlist of collectible-brick set indices and benchmarks (S&P 500, Gold, Bitcoin) in your toolbar or side panel. CBX puts a clean, glanceable watchlist of collectible-brick set indices right in your browser — no tab, no clutter. Click the toolbar icon for a compact dropdown, or dock it to the side panel to keep it visible while you browse. WHAT YOU GET • Your chosen indices and benchmarks in one small list — level, change, and a mini trend line for each. • A quick range switch: 1W / 1M / 1Q / 1Y. • Traditional benchmarks side by side: S&P 500, Gold, and Bitcoin. • One click opens the full factsheet on the CBX site. • Pick exactly what you track — flagship indices, theme indices, minifigure indices, or benchmarks. PRIVACY • No account, no sign-in, no tracking. • Your only saved setting (which rows you picked) stays on your device. • The extension reads one public, read-only data endpoint to show current levels.
