About Stackd
Stackd is a free LEGO collection tracking app for LEGO fans and collectors. Log every set you own, have built, or want to build — then rate each one across five criteria: build experience, complexity, display value, parts quality, and value for money. It is a free, mobile-first web app available at stackd.community — no download or app store installation required.
Stackd is a community-first platform. Ratings are first-party — collected directly from real collectors on Stackd, not aggregated from other sites. No sponsored placements, no algorithmic manipulation — just honest data from people who love the hobby.
- ▸ Catalogue every set you own, have built, or have wishlisted
- ▸ Rate sets across five independent criteria and leave a written review
- ▸ Browse community ratings to decide what to build next
- ▸ Follow other collectors and see what they've been logging
