BrickPulse - Sync your LEGO inventory across BrickLink, BrickOwl & eBay

Hey Product Hunt 👋 I'm Cody, the solo maker behind Brick Pulse. I sell LEGO across BrickLink, BrickOwl, and eBay, and the worst part of the job was never sourcing or packing — it was keeping inventory straight across three marketplaces. Sell a minifig on eBay, then scramble to pull it from BrickLink before someone else buys it. I got tired of overselling and the spreadsheet gymnastics, so I built the tool I wanted. Brick Pulse treats BrickLink as your master inventory and automatically pushes stock and price changes out to BrickOwl and eBay. List once, sell everywhere, stop double-selling parts you no longer have. There's a free Collector tier, and the Seller tier is a flat $15/month — no per-listing fees, no card required for the 7-day trial. It's still just me building this, so I'd love your honest feedback, especially from anyone who's wrangled multi-channel selling in any niche. Happy to answer anything below. 🧱
