We built these because we needed them ourselves. Every tool runs entirely in your browser — nothing is uploaded, nothing is stored, there is no sign-up and no limit on how often you use them. If one of them saves you an hour, that is the point.
What the tools cover
- Marketplace Title Generator — checks a product title against the character limits and banned words of Amazon, Allegro, eBay, Etsy, Cdiscount and OTTO before you list.
- Amazon Listing Checker — measures bullets, description and backend search terms in bytes, and flags duplicates and words that get listings suppressed.
- Google Snippet Preview — shows how a title and meta description render in search results, measured in pixels rather than characters.
- Marketplace Margin Calculator — works out what is left after commission, VAT, shipping, advertising and returns, channel by channel.
- Product Image Checker — checks a folder of photos against the size, background and file-weight rules of nine sales channels.
- EAN Generator — creates structurally valid EAN-13, EAN-8, ISBN and IMEI numbers for testing imports, PIM set-ups and label templates.
- Amazon.de Compliance Checklist — the registrations a foreign seller needs before listing in Germany: WEEE, LUCID packaging, GPSR and VAT.
Who they are for
Shopify and marketplace sellers who list across several channels and keep running into the same rejections: titles cut off, listings suppressed, images refused, and margins that looked fine until the commission statement arrived. Each tool answers one of those problems in about a minute, for one product at a time.
When a tool is not enough
If a tool shows the same problem on every product you test, it is a data problem worth fixing once, at the source. Running the same checks across a whole catalogue with scripts and validated upload files is what we do in listing production, and the store and channel audit shows where the gaps cost the most.
