A CDN isn't one cache. It's hundreds of independent ones, and most of them are cold. Cloudflare alone runs 300+ data centers, and each keeps its own cache. A page cached in Frankfurt is still ice cold in Tokyo, so the first visitor per region pays the full origin round trip. In our measurement of...

Questions & Answers

As answered by people managing Stackra.app and warmup.rocks.

What makes your product unique?

Stackra.app's answer

Most website audit tools hand you a Lighthouse report and walk away. Stackra is different in three ways. It knows your platform: Stackra detects whether your site runs on WordPress, Shopify, Wix, Squarespace, or Webflow and limits every recommendation to changes you can actually make on your specific setup. It reviews your site the way a consultant would: a CMO review checks messaging, trust signals, and CTAs; an SEO and GEO review covers traditional search and AI search visibility in ChatGPT and Perplexity; a CTO review covers Core Web Vitals, performance, and security. Then it tells you what to fix first: everything compiles into a Growth Readiness Score (0-100) and a prioritized action plan, not an exhaustive issue dump.

warmup.rocks's answer:

Most cache warmers run from one server, so they only warm the one CDN edge location that server happens to hit. CDNs like Cloudflare cache per data center, 300+ of them, and a HIT in Frankfurt says nothing about Singapore.

warmup.rocks is different:

  • Warms from 42 countries on 6 continents, so the cache gets filled where your visitors actually are
  • Verifies every response (cf-cache-status, x-cache) instead of just firing requests and hoping
  • Shows hit ratio per edge location, so you see whether warming actually works
  • Nothing to install: no plugin, no script tag, no DNS change

Why should a person choose your product over its competitors?

Stackra.app's answer

Stackra is the only free website grader that covers platform-aware recommendations, AI search visibility (GEO), and three expert perspectives in one report. SEOptimer starts at $19/month with no free plan. Sitechecker starts at $49/month, trial only. HubSpot's Grader checks your homepage and gives you four scores. Stackra crawls up to 20 pages, detects your platform, and delivers three AI expert reviews with a ranked action plan. Free to start, no credit card required.

warmup.rocks's answer:

Three reasons:

  • Geography. Competitors warm from a single region. We warm from 42 countries, which is the whole point of a CDN cache.
  • Verification. We read the cache status header of every single response and report the actual hit ratio per location, so you see whether warming works instead of taking it on faith.
  • Deploy integration. A deploy hook or our GitHub Action re-warms the cache right after you ship, which is exactly when it's coldest.

Plans start at $15/month with a 7-day free trial.

How would you describe the primary audience of your product?

Stackra.app's answer

Small business owners, solo founders, and early-stage teams who want a clear diagnostic and action plan without agency costs or ongoing subscriptions. Typically owners and operators without an in-house marketing or technical team who want to know why their site isn't converting and what to do about it.

warmup.rocks's answer:

Developers, agencies and store owners who run sites behind a CDN (Cloudflare, Fastly, CloudFront, Akamai, bunny.net) and serve visitors in more than one region. Typical cases:

  • WordPress/WooCommerce sites where preload plugins stop at the server cache
  • Shopify and Magento stores with a long product tail that never stays warm on its own
  • Anyone whose deploys purge the edge cache and leave the first visitor per location with a slow load

What's the story behind your product?

Stackra.app's answer

Stackra came from a simple frustration: the best website analysis tools are built for SEO agencies running dozens of audits a month, not the business owner who wants to understand their own site. We built Stackra to give small businesses the same quality of analysis that larger companies pay consultants thousands of dollars for, free.

warmup.rocks's answer:

I run a web agency in Switzerland, and for years I believed our sites were fast because we put them behind Cloudflare and saw HIT in the headers. Then I measured from other continents: pages that loaded in milliseconds from Zurich took multiple seconds from Tokyo or São Paulo, because each edge location keeps its own cache and most of them were cold.

I built a warmer for our own client sites first, then measured 408,000 CDN requests and found a miss is 3.5× slower than a hit at the median. That data convinced me this should be a product.

Which are the primary technologies used for building your product?

Stackra.app's answer

Typescript, React, Node.js, PostgreSQL, Playwright for headless browser crawls, and OpenAI for the AI persona reviews.

warmup.rocks's answer:

  • Node.js + TypeScript with Hono as the web framework
  • SQLite for storage
  • Astro for the public site, vanilla JavaScript for the dashboard
  • Warming requests go through dedicated datacenter proxies in 42 countries

The whole thing runs on a plain VPS behind Cloudflare, which keeps it fast and cheap without a pile of infrastructure.

Who are some of the biggest customers of your product?

Stackra.app's answer

Stackra is a free tool built for SMB owners, so our users span local service businesses, e-commerce stores, professional services firms, and early-stage SaaS startups. We built it for the owner-operator, not the enterprise.

warmup.rocks's answer:

  • this:matters GmbH (the Swiss web agency behind the product, running client sites through it)
