Why use Spirit Fish?

Deployments, JS rendering, and content delivery without the hassle.

Crawlable SEO & Metatags

No need to lock in to a specific technology or spend tons of time to make sure your site is SEO-friendly.

No Code Changes Required

No need to refactor your code to make your website crawlable. Quickly make changes in our dashboard.

Quick Cache Invalidation & API

Invalidate your cache in the dashboard, or via our API, so that crawlers always get your site's most up-to-date information.

CDN Backed Static Asset Hosting

When someone accesses your domain, we'll pull the assets from your hosting URL, render, and cache the output on the fly!

Uses Inline Critical CSS

Your users won't see a flash of unstyled content in the time it takes to load your first CSS file.

Supports XHR Caching

Optionally capture your in-page requests at the time of render to avoid your end users making double requests for unchanged resources.
