About Supabase's Website
Supabase (supabase.com) is a developer tools website. Our AI analyzed its design, copywriting, SEO optimization, performance metrics, and user experience to generate this comprehensive website score.
With an overall score of 76/100 and a grade of B, here's what our AI found:
Detailed Breakdown
Supabase UX Score
“Your experience design is thoughtful, but the experience itself is a slow, painful marathon when it should be a sprint.”
Accessibility at 95/100 is excellent—your site is usable for everyone, which shows respect. You have proper viewport settings, favicon, and CTA buttons in place. However, the browser console errors are noise that make developers distrust you (even if it doesn't break anything visually). The Time to Interactive at 13/100 is brutal; users see your site but can't interact with it. That's UX death. Your heading structure issue (not strictly sequential) is fixable in 30 seconds. The real pain point: users wait 7+ seconds for Largest Contentful Paint. By the time your site is usable, half your traffic has left to check Stripe or Firebase.
Supabase SEO Score
“Your SEO is so perfect it's almost suspicious—perfect score means you're either a bot or actually competent.”
100/100 on Lighthouse isn't luck. You've got proper title, solid meta description, OG tags dialed in with correct dimensions, structured linking (107 internal, 86 external), and alt text on every single image (0 images without alt). Your og:image dimensions are 800x600, perfect for social cards. Heading structure reads left to right. This is genuinely excellent foundational SEO work. Don't break this—it's your golden goose.
Supabase Copy Score
“Your messaging is crisp—too bad users can't read it while waiting for JavaScript to finish its existential crisis.”
The meta description is punchy and tells users exactly what they're getting (Postgres, Auth, APIs, Realtime). Your feature-based H2 structure is scannable and clear. But here's the problem: no H1 tag. That's like showing up to a wedding without the bride. Adding a single, clear H1 about being 'The Postgres Development Platform' (which is already in your meta) would fix this SEO miss instantly. The 2,491 word count is healthy for content depth—you're not being lazy, which is refreshing.
Supabase Design Score
“Your design is clean, but your JavaScript is a hoarder's attic.”
The visual hierarchy is solid and modern—no obvious crimes against aesthetics here. However, you're displaying 185 images like you're running an art gallery, yet only 4 of them actually matter to the average visitor. The layout itself works, but your CSS is doing the limbo: how low can it go? You're carrying unused CSS like luggage you forgot you packed. Trim the fat and your design score jumps 15 points instantly.
Supabase Performance Score
“61 on Lighthouse, 7.6s LCP, 180ms FID—you're the startup equivalent of a sports car with the acceleration of a minivan.”
This is the disaster zone. Your Largest Contentful Paint is 7.6 seconds when users start rage-clicking after 3 seconds. The Lighthouse report screams: 38 external scripts, massive JavaScript bundles, unused CSS, unused JavaScript, forced reflows, and no source maps. Your main thread is busier than a barista at Starbucks on Monday morning. You're loading things that don't render anything meaningful. Start with: defer non-critical JavaScript, tree-shake your unused code, implement lazy-loading for those 185 images (you're probably loading 30 of them above the fold), and use a CDN aggressively. Performance is your enemy; treat it like one.
