mktbox: free marketing tools

Free marketing tools for the page you're on. No account, no paywall, nothing to upgrade. Click the mktbox icon on any page to: • Make a QR code for the page. Download it as a PNG, or open it in the full QR generator to add your logo, colors and a frame. It never expires. • Build a tagged UTM link. Pick where you're sharing it (LinkedIn, Instagram, newsletter, Google Ads…), name the campaign and copy. Turn the tagged link into a QR code in one click. • Check the page before you share it: see how its link preview looks on LinkedIn, X and WhatsApp, run a speed audit, score the page title, or run a vibe code audit on apps built with Lovable, Base44 or Bolt (SEO, security and speed). Right-click for more: • Selected text: score it as a headline, or find keyword ideas for it. • A link: check its preview or make a QR code for it. • An image: resize it for every social size at once, or turn it into a subtle animated GIF. Made by mktbox.xyz, a set of free, open source marketing tools for marketers, founders and creators. Privacy: the extension only sees a page when you open it or use the right-click menu there. Nothing is stored or sent unless you click to open a tool. Full policy: https://mktbox.xyz/privacy
