Why is my Squarespace site slow?

Three usual suspects: unoptimized hero images, render-blocking fonts, and custom code injecting layout shifts. We audit and tune what's tunable, but Squarespace's framework baseline caps how fast a site can get.

How do I migrate off Squarespace?

Site export gives you a WordPress-format XML of basic pages and posts only. Media, custom CSS, and Gallery/Album pages must be redone manually. We rebuild on Next.js + Sanity or Webflow depending on whether you want code or no-code going forward.

Should I enable Developer Mode?

Only if you're committing to staying. Developer Mode locks you out of template updates, prevents template switching, and deletes all customizations if you disable it. Most teams who turn it on regret it.

Security issues we find in Squarespace apps

Patterns documented in primary-source research. Most of these ship to production by default.

Custom Code Injection breaks Core Web Vitals

Per multiple SEO-agency writeups, custom code is the #1 cause of CLS/LCP failures. A single syntax error or specificity conflict breaks layout site-wide.

Heavy hero images and unoptimized assets

Squarespace serves originals without aggressive resizing for mobile breakpoints.

Render-blocking fonts

Default font loading strategy causes FOUT/FOIT on first paint.

Developer Mode lock-in

Once enabled, you can't switch templates, you don't receive template updates, and disabling Developer Mode deletes all customizations.

No backend execution

No server-side code at all. Any 'logic' lives in client JS, including any kind of validation. All bypassable.

API rate limits cripple integrations

40 req/hour quoted in agency writeups. Real-time inventory sync impossible.

Site export is XML only

No images, no Gallery pages, no Album pages, no e-commerce data, no custom CSS.
