"A free collection manager and valuation database that aggregates multi-source pricing data with AI-powered EOL forecasting for LEGO investors."
Built by Nic (independent developer)
4.2 / 5.0
Overview
MyBricks.net is a comprehensive LEGO set database and personal collection manager built and maintained by a solo developer known as "Nic." Described by its creator as "probably the largest and most comprehensive database of LEGO bricks," it aggregates set data from eBay, the official LEGO store, Amazon, and Brickset into a single unified platform. Users add sets to their virtual collection and the site automatically supplies pricing data, part counts, current market valuations adjusted by condition (sealed, opened, built), investment scores, and EOL (End of Life) forecasting. The platform supports English and German and is a non-commercial passion project with no corporate sponsor.
Pros
- Genuinely comprehensive investment-focused database aggregating eBay, LEGO, and Amazon data with AI-calculated EOL scores and forecast values, giving collectors a single source of truth for investment decisions.
- Completely free with no ads or paywalls — delivers sophisticated valuation features at zero cost, making it accessible to all collectors regardless of budget.
Cons
- Solo-developer fragility — the entire platform depends on one person, making updates slow and the project vulnerable to going unmaintained without warning.
- A significant number of LEGO product lines are excluded by default (Duplo, Baby, Gear, Books, etc.), limiting usefulness for collectors outside the core investment-grade theme set.
Deep Dive
MyBricks.net occupies a specific niche: the collector who treats their LEGO sets less as building material and more as a portfolio of appreciating assets. The platform's core value proposition is removing the spreadsheet labour that serious LEGO investors otherwise maintain manually. Add a set, and MyBricks enriches it automatically with current eBay market prices, LEGO store pricing, Amazon listings, an EOL score, and a forecast value — a proprietary estimate of what the set is likely to be worth after it retires. The condition-based valuation is a particularly practical touch; a sealed box and an opened, unbuilt set fetch different prices in the secondary market, and the platform accounts for this.
The AI-driven EOL Score is the platform's most distinctive feature and its clearest differentiator from tools like BrickEconomy. Rather than just showing historical price charts, it attempts to predict which currently-available sets are worth stocking up on before discontinuation — the core question every LEGO investor wants answered. The platform explicitly excludes themes with low investment relevance (Duplo, Baby, Gear, Books) to focus its data quality where it matters most: sets with meaningful secondary market activity. The solo-developer model is both a strength (the creator is a collector building exactly what they need) and a risk (there is no team, no SLA, and no guarantee of longevity). For now, it delivers a genuinely useful free tool for investment-minded AFOLs who would otherwise rely on a combination of BrickEconomy, a personal spreadsheet, and regular eBay searches.

Editor's Review
MyBricks.net punches well above its weight for a solo-developed passion project. The combination of multi-source data aggregation and AI-calculated EOL forecasting gives it a feature set that paid platforms would struggle to match. For a collector whose primary question is "which sets should I buy sealed and hold?", MyBricks provides a surprisingly coherent answer — and it does so entirely for free.
The platform's Achilles heel is its dependence on a single developer. Feature requests move slowly, some themes are simply absent, and the social presence is minimal. But as a free, no-nonsense investment tool for the serious sealed-set collector, it deserves far more attention than its small footprint suggests.
