Everything you need to master your collection

Built for LEGO enthusiasts who take their collection seriously.

📷
AI Brick Recognition

Point your camera at any brick and StudStack identifies it instantly using Brickognize AI.

📦
Smart Inventory

Organize every brick by storage location. A simple location code like 01.02.03 tells you exactly where to look — configurable to your setup.

🧱
Set Builder

Load any LEGO set by number and track your building progress. See exactly which parts you have, which are missing, and where to find them.

🔗
BrickLink Integration

Look up part details and colors directly on BrickLink. Export missing pieces as a Wanted List XML — ready to order in one click.

🌈
Color & Quantity Tracking

Track exactly which colors and how many of each brick you own. Color availability shows up directly in the set builder — no guessing what you have.

🔒
Two-Factor Authentication

Protect your collection with TOTP two-factor authentication — free for every account. Works with Google Authenticator, Authy, and any standard authenticator app.

Bulk Add

Scan or type a whole batch of bricks and assign them all to one storage location at once. Cataloguing a new set or sorting a tray takes minutes, not hours.
