What it does

Four tools, one panel

Everything appears on the Etsy page you're already looking at. Nothing to set up.

Profit

Know exactly what you keep

Enter your cost and shipping and SellerLens shows your real net profit and margin % after every Etsy fee — listing, transaction, payment, and optional Offsite Ads. A dedicated “shipping charged to buyer” field keeps the math honest.

Optimize

A 0–100 listing quality score

SellerLens reads your title, photos, description and tags and scores the listing, then hands you the top improvements to make it rank and convert better.

Analyze

Snapshot any shop, export to CSV

Open a shop page and SellerLens captures a clean summary — visible listings and price stats — that you can export to CSV in one click.

Trust

Private and safe by design

SellerLens is read-only: it never clicks, edits, relists, or automates anything on Etsy, so there's no account-ban risk. It runs entirely in your browser with no server and no tracking.

🔒

✓ Runs 100% locally — no server, no account
✓ No tracking, no analytics, no data leaves your device
✓ Read-only — never edits or automates anything on Etsy
✓ Minimal permissions (only the Etsy page you're viewing)

Which marketplaces are supported?

Etsy today. The design makes it straightforward to add other marketplaces later.
