The Quiver · Centaur's toolbox
A growing set of genuinely useful tools for anyone starting a website, a shop or a side business — free to use, no sign-up. A Quiver membership adds saving, history and CSV export across the lot — and it's included free with Standard hosting and up.
A word or two about your idea, in — clean, brandable domain ideas out, sorted by style. Each one links straight to a live availability & price check.
Company-name ideas — evocative, descriptive, or with your own name on the door — each with a one-click jump to a matching domain.
One take-home figure in — see what to list at, and what you keep, on Amazon, eBay and Etsy side by side, at once.
Add up your costs, choose a margin or markup, and get the price to charge — with profit per unit and break-even. The starting point before marketplace fees.
Wix, Squarespace and Shopify vs your own site — the real yearly cost at your sales volume, and the part nobody mentions: whether you can ever take your shop with you.
Enter what you want to keep per unit; it solves for the list price — referral fees, FBA, the minimum fee, closing fees and the UK Digital Services Fee. Amazon UK or US.
Final value fee, per-order fee, the UK regulatory fee and VAT — UK (private or business) or US. Tells you what to list at to hit your target.
The whole stack — listing fee, 6.5% transaction fee, processing, the regulatory fee, optional Offsite Ads and VAT. UK, US or EU.
Fill in your details, add line items, download a clean professional PDF — VAT, logo and your own branding. Nothing leaves your browser.
A clear, GDPR- and CCPA-aware privacy policy and terms of service, built from what your site actually does. Copy, download or print.
Turn a logo or a letter into a crisp favicon in every size a browser, phone and app asks for — plus the HTML to paste in.
Point it at any site and see the certificate (issuer, expiry, validity) and whether it's online and quick to respond.
Check any domain's MX, SPF, DKIM and DMARC records in seconds — and see, in plain English, why your emails might be landing in spam.
Build a clean, commented .htaccess for Apache/LiteSpeed — force HTTPS, fix www, add 301 redirects, error pages, caching and security headers.
Your own domain, mailboxes and hosting — UK-billed, plainly priced, SSL on every site, set up the same day.
