About Polymer

Web Components were a standard before they were a working feature. Custom elements, shadow DOM and HTML templates were agreed on paper while browsers shipped them at different speeds and with different bugs, and for several years the only practical way to build with them was to bring your own implementation.

Polymer was Google's answer to that gap, released in 2013 under a BSD license and written in JavaScript. The library supplied polyfills and a thin layer of sugar so teams could write components against the standard before the platform was ready for them, and much of what it proved in practice fed back into the standards themselves.

Browsers then caught up, the vendor moved its effort to a lighter successor, and new projects stopped starting here. What remains is the more interesting object. As of October 2026 we detect the library on 38 sites, and a count for a framework nobody chooses any more is not a popularity measure at all. Instead it is an inventory, an estimate of how much production code was written against a superseded approach and is still being served to real visitors every day.

Inventories of that sort have buyers. Agencies pitching rebuilds want to know which companies are still carrying one. Security teams care because an unmaintained front-end dependency is a dependency nobody is patching. Framework maintainers and hiring researchers care about the decay curve itself, since the rate at which an obsolete library leaves the web is one of the few honest measures of how long a front-end decision really lasts.

Two limits apply. Detection depends on the library announcing itself through recognizable globals, element registrations or asset paths, and a build step that bundles and minifies everything into a single file can hide it completely, so the true figure is higher than the one we publish. We also record no version for this entry, which is a genuine loss, because the migration distance from an early release to a modern component stack is nothing like the distance from a later one, and a buyer sizing that work would want to know which they are looking at.

A per-domain lookup tells you that one site is still on it. The downloadable list tells you how much of the stock is left, who owns it, what else those sites run, and how the total moves from one release of the dataset to the next, which is the only way to watch a technology actually die rather than assume it already has.

Frequently asked questions

How many websites use Polymer?

webatla detects Polymer on 38 websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using Polymer?

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 Polymer?

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

What else is in the Polymer technology data?

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

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

Both. Every site running Polymer 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 Polymer?

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 Polymer 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.
