About RackCache

RackCache is not something a visitor can see. What a crawler can see is the header it leaves behind on the way out.

Introduced in 2008 and published under the MIT license, RackCache is a Ruby middleware that puts HTTP caching inside the application instead of in front of it. The middleware implements the parts of the specification that make caching safe, including expiration, validation, conditional requests and handling of ETag and Last-Modified. Rails and Sinatra apps are the usual hosts.

Presence tells you three things at once. The application is Ruby and Rack-based, which narrows the backend to a small family of frameworks. Somebody on the team thought about caching, which is not universal. And caching was solved in the application layer rather than by putting Varnish, nginx or a CDN in front of it, which is a real architectural preference and often a sign of a self-managed deployment rather than a platform-managed one.

The detection is inferential and the count is conservative. We recognize the middleware from the diagnostic header it can add to responses, and that header can be switched off, stripped by a proxy, or hidden behind a CDN that answers before the origin ever does. As of September 2026 the technology is visible on 13,858 sites, a figure best read as the subset that talks about itself rather than as the installed base.

For a researcher the value is population-level. A list of Ruby applications that cache at the middleware layer is a starting point for sizing the Rack ecosystem, for finding self-managed deployments that a hosting or CDN vendor could serve better, and for studying how much of the Ruby web still runs its own caching rather than renting it. Each domain in the file carries the rest of its detected stack alongside, so the column works best as a filter rather than as an answer on its own.

Frequently asked questions

How many websites use RackCache?

webatla detects RackCache on 14K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using RackCache?

Yes, as structured JSONL. Grab a free sample first.

What's included for each site, and how fresh is it?

Domain, DNS, RDAP/WHOIS, the full technology stack, IP & country, PageRank and Harmonic, re-detected and re-exported daily.

How do I find the websites using RackCache?

Buy the technology dataset, then download the complete list of domains we detect using RackCache, re-exported every day.

What else is in the RackCache technology data?

Each row places RackCache next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.

Can I download just the sites using RackCache, or the whole database?

Both. Every site running RackCache comes in the Technologies dataset, one downloadable file. Or buy All data for the entire database: technologies plus identity, ranking, DNS and RDAP/WHOIS for every domain, combined in one file. Daily fresh export.

How do I download the list of websites using RackCache?

Three steps: (1) grab the free 10,000-row sample to inspect the schema, (2) buy the Technologies dataset, (3) download the full list of every domain we detect running RackCache as a JSON Lines file. It is re-exported daily, so you can re-download the freshest list any time inside your access window. Each row carries the domain plus DNS, WHOIS, IP, hosting country and rank.
