RuleSnapper: Know When Marketplace Rules Change

Marketplace platforms quietly update their catalog rules, and sellers don't always find out until something gets removed.

I had a six-month-old listing taken down for violating a rule change I never knew existed. When I went looking for when the change happened and what had changed, I couldn't find anything. Rule updates rarely get announced unless there's a PR story attached. That leaves individual sellers and buyers trying to keep up with enforcement tools they can't see.

So I built something about it.

RuleSnapper tracks changes to marketplace catalog rules, starting with Vinted across all 26 country markets. It snapshots the rules regularly, records the differences, and lets you browse exactly what was added or removed over time.

• Browse the full change history, no account needed
• Subscribe to email or RSS notifications for the markets you care about (free account required)
• Each change comes with an AI analysis explaining what it means for sellers
• Currently tracking: Vinted × 26 countries

It's a side project, still early days, but if you sell on Vinted it might save you a surprise.

I've already found it useful myself and it's ready for others. Give it a whirl, I'd love to hear from you.
