This Squarespace site is rendered using serverless technology.
It is proxied through Cloudflare Worker that is pointed at this domain.
It even has a “developer” version — worker updates are deployed to a separate worker that proxies to dev.otters.life.

FEATURES

Image Optimization
Images are proxied through Cloudflare’s Image Optimization product.
Since our images are versioned, cache is automatically invalidated whenever the image changes (known as “revving”).
⬅ This image would normally be served as JPEG. It is now served in the AVIF format. This is more optimal than WebP in many cases!
JPEG Size: 149 kB
WebP Size: 81.3 kB
AVIF Size: 66.4 kB 🔥
GIFs — one of the heaviest image formats on the web — are also optimized!
This GIF is served in the WebP format ➡
GIF Size: 1.5 MB
WebP Size: 378 kB 🔥
And yes, they support animation 😱

HTTP/3 and Compression
Requests are served using HTTP/3
If it’s proxied by the worker, it automatically serves it through HTTP/3.
No more head of line blocking!
Even better, this reduces the number of domain lookups and TCP connections down to one.
All resources proxied through the worker are served using Brotli by default, including third parties.
This includes:
HTML
Scripts
Stylesheets
Fonts
Even API requests!
