CacheBoost automatically pre-loads your pages before visitors arrive: better page rendering, better TTFB for your users and search engine crawlers (SEO/GEO).
Without warming, the first visitor after a cache flush pays the full generation cost — sometimes 5× slower than cached pages. That means bad UX, lost conversions, and lower SEO rankings.
Cold pages generate fully on each request. Your server works hard, your visitor waits.
Core Web Vitals (LCP, TTFB) degrade when search engine crawlers hit an empty cache.
Every 100ms of latency can cost up to 1% in conversions. Cold caches add seconds.
Verify ownership of your domain in one click with a simple file upload or meta tag.

See how SEO and AI crawlers (Googlebot, GPTBot, ClaudeBot, PerplexityBot…) hit your cache, with hit/miss rates over time from Cloudflare or WordPress.
CacheBoost warms over 1 million URLs per day and sustains a 98% cache hit ratio, cutting typical time-to-first-byte (TTFB) from 800–2000ms on a cold cache to under 200ms warm — across 4 always-on warming regions.
Cache warming is the practice of proactively requesting a site's pages right after a cache flush — before real visitors or crawlers arrive — so every subsequent request is served from a warm cache instead of triggering a slow, uncached rebuild.
A cold cache is the state of a page whose cached copy is missing or has just expired. The next request can't be served from cache, so the origin server has to rebuild the page from scratch, making it markedly slower than a cached response.
Cache hit ratio is the percentage of requests served directly from cache instead of the origin server. A ratio above 90% is considered healthy; below 70% usually signals a configuration issue or an unwarmed cache.
TTFB is the time between a browser sending an HTTP request and receiving the first byte of the server's response. It measures raw server responsiveness and is the foundation Google's LCP (Largest Contentful Paint) metric is built on.
CacheBoost works with any CDN that serves content via HTTP — Cloudflare, Fastly, BunnyCDN, KeyCDN, and more. If your CDN caches HTTP responses, CacheBoost can warm it.
Absolutely. CacheBoost works with any caching layer — not just CDNs. If your site uses Varnish, Redis, a file cache, a database cache, or any HTTP-based caching system, CacheBoost can warm it. As long as your pages are served faster on the second request, CacheBoost is useful.
Warming requests are sent at a controlled rate to avoid overloading your origin server. You can configure the concurrency and request rate per job.
CacheBoost provides a webhook URL you add to your CI/CD pipeline (GitHub Actions, GitLab CI, etc.). One line of config is all it takes — warming starts automatically as soon as your deploy finishes.
No problem. CacheBoost handles multi-level sitemaps, sitemap index files, and Google Shopping feeds natively, with no limit on the number of URLs per job. Every page gets warmed, regardless of the size of your site.
CacheBoost only sends HTTP requests to your public URLs — the same requests any visitor would make. No credentials, no private data is ever accessed.
