    While StackBlitz is accessible on mobile devices, the user experience is not as optimized as it is on desktop browsers.

Questions & Answers

As answered by people managing StackBlitz and ListingSafe.app.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

ListingSafe.app's answer:

Independent Etsy sellers and small handmade shops — ListingSafe is a tool for individual sellers, not enterprises

How would you describe the primary audience of your product?

ListingSafe.app's answer:

Etsy sellers, mostly solo makers and small shops, who want their listings found in search without brand names in the title or tags, and who want to see what's selling in other shops before they write their own.

Why should a person choose your product over its competitors?

ListingSafe.app's answer:

eRank, Marmalead and Alura are built around keyword research. ListingSafe works on the listing itself: one scan gives a search score, a new title, 13 tags and description, and flags the trademarked words and policy problems that get listings taken down. Words like "Koozie" and "Onesie" are registered trademarks, and that's the kind of thing it catches before you publish. It also analyses any shop (what's selling and the tags behind it), writes new listings, and checks where your listing photos show up.

What makes your product unique?

ListingSafe.app's answer:

It checks and optimizes in the same scan. The SEO rewrite (a new title, 13 tags and description) goes through the trademark check, with the USPTO record when a flagged word is a registered mark, so the rewrite never brings a brand name back in. The free Chrome extension shows the real tags on any Etsy listing with trademarked words marked red, so you can see what other shops use without copying a brand name into your own tags.

    I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.
