## What is CacheBoost?

CacheBoost is a distributed cache warming platform. It pre-warms CDN and reverse-proxy caches by simulating real HTTP traffic — ensuring end users always hit cached content instead of a cold origin.

CacheBoost automatically crawls your pages before visitors arrive: better page rendering, better TTFB for users and search engine crawlers (SEO/GEO).

**Key stats:** 5M+ URLs warmed per day — 4× average speed improvement — available in 4 regions.

## The problem: cold caches

Without warming, the first visitor after a cache flush pays the full generation cost — sometimes 5× slower than cached pages.

- **Slow first byte** — Cold pages are generated on each request. Your server works hard, your visitor waits.
- **SEO impact** — Core Web Vitals (LCP, TTFB) degrade when crawlers hit an empty cache.
- **Lost conversions** — Every 100ms of latency costs up to 1% in conversions. Cold caches add seconds.

## How it works

1. **Add your site** — Verify domain ownership with a file upload or meta tag.
2. **Configure a boost** — Point CacheBoost at your sitemap, choose regions, user-agents, and a schedule.
3. **Stay warm** — CacheBoost crawls and pre-loads your pages automatically, on your schedule.

## Key features

- **Sitemap-based crawling** — Automatically discovers and warms all URLs from standard or nested XML sitemaps.
- **Multi-region warming** — Warm from France, USA, Germany, UK — reduce TTFB for visitors worldwide.
- **User-agent variations** — Simulate desktop, mobile, bots, and AI crawlers — fills every cache variant.
- **Flexible scheduling** — Run on a cron schedule. Choose interval, time of day, or trigger after deployments.
- **Email reports** — Get a summary after each warming run: URLs hit, errors, and performance data.
- **CMS compatible** — Works with WordPress, WooCommerce, Magento, PrestaShop, Shopify, Drupal, Symfony, Laravel, TYPO3, Joomla, and custom stacks.

## Frequently asked questions

**What is cache warming?**
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.

**What is a cold cache?**
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.

**What is cache hit ratio?**
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.

**What is TTFB (Time to First Byte)?**
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.

**Does CacheBoost work with my CDN?**
Yes. CacheBoost works with any CDN that serves content via HTTP — Cloudflare, Fastly, BunnyCDN, KeyCDN, and more.

**Does it work without a CDN?**
Absolutely. CacheBoost works with any caching layer — Varnish, Redis, file cache, database cache, or any HTTP-based caching system.

**Will warming requests affect server load?**
Warming requests are sent at a controlled rate. You can configure concurrency and request rate per job.

**How does the post-deploy trigger work?**
CacheBoost provides a webhook URL you add to your CI/CD pipeline (GitHub Actions, GitLab CI, etc.). Warming starts automatically when your deploy finishes.

**What if my site has thousands of URLs?**
No limit. CacheBoost handles multi-level sitemaps, sitemap index files, and Google Shopping feeds natively.

**Is my data safe?**
CacheBoost only sends HTTP requests to your public URLs — the same requests any visitor would make. No credentials or private data is ever accessed.

**Can I cancel anytime?**
Yes. No commitment, no cancellation fee. Cancel at any time from your dashboard.
