Verdict

Dribbble is delivered through Amazon CloudFront and serves content with remarkably efficient network requests—just 2 requests totaling 676 KB. Its greatest strength is the lean architecture that achieves solid 73-point performance while keeping carbon emissions minimal at 0.277 grams per session. Adding Content-Security-Policy and Permissions-Policy headers would immediately strengthen the B-grade security posture and close the most critical compliance gaps.

Questions

How do I find out what a website is built with?

Paste the address into Sniff. It fetches the page once and looks for the fingerprints that frameworks, CMSs, hosting providers, CDNs and analytics tools leave in the HTML, response headers, loaded files and cookies, then lists everything it recognises.

Is Sniff free?

Yes. Sniff is free, needs no sign-up and stores nothing about you. Reports for popular sites are cached for a week so they load instantly.

How is the carbon footprint calculated?

Sniff weighs every file the page loads and applies the Sustainable Web Design model: about 0.81 kWh per gigabyte transferred at the global average grid intensity of 494 g CO2e per kWh, then grades the result from A+ to F.

What does the security grade mean?

It checks six HTTP security headers (HSTS, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy and Permissions-Policy), whether the site uses HTTPS with a valid certificate, and whether it reveals server versions.

Can I compare two websites?

Yes. Choose Compare two, enter both addresses and Sniff shows them head to head on speed, security, carbon, page weight and tech stack, with a winner.

What technologies can Sniff detect?

About 110, including Next.js, React, Vue, Angular, Svelte, WordPress, Shopify, Webflow, Wix, Tailwind, Bootstrap, Cloudflare, Vercel, Netlify, AWS, Google Analytics, Stripe, Razorpay, Intercom and many more.
