ListingSafe — Protect Your Etsy Shop from Trademark Violations
How often each product is chosen within a category, 0–100% relative to the other.


As answered by people managing StackGo and ListingSafe.app.
ListingSafe.app's answer:
ListingSafe checks trademarks against the live USPTO database instead of a static keyword list, so results reflect actual current registrations. It also goes beyond detection: it suggests safer rewrites for risky wording and can generate an appeal letter if a listing has already been taken down.
ListingSafe.app's answer:
Most Etsy tools (eRank, Marmalead, Alura) focus on SEO and keyword research. ListingSafe solves a different problem: avoiding trademark and policy takedowns. If you sell personalized or fan-adjacent items and worry about words like "Koozie" or "Onesie" being trademarked, that's exactly what ListingSafe checks for.
ListingSafe.app's answer:
Etsy sellers — mostly solo makers and small handmade shops who sell personalized or custom items and want to make sure their titles, tags, and descriptions won't trigger a trademark complaint or policy violation.
ListingSafe.app's answer:
It started after seeing how many Etsy sellers get blindsided by trademark takedowns — often for words they had no idea were trademarked. Reinstating a suspended listing is stressful and slow, so ListingSafe was built to catch those problems before publishing instead of after.
ListingSafe.app's answer:
ListingSafe runs on Spring Boot with PostgreSQL, hosted on Railway. Scanning is powered by Google Gemini combined with a curated trademark/policy rules library and live USPTO API lookups. Billing is handled by Paddle, and the browser extension is built on Chrome Manifest V3.
ListingSafe.app's answer:
Independent Etsy sellers and small handmade shops — ListingSafe is a tool for individual sellers, not enterprises
