About Stencil

The Web frameworks label is the first thing to put aside here. Ionic built the tool as a compiler, so developers write components in TypeScript, the work happens once at build time, and what reaches the browser is plain custom elements that run under any framework or under none, with nothing left over that behaves like a framework itself.

The compilation step is what complicates detection. A framework that ships a runtime announces itself, because the runtime is a file with a recognisable name and shape. A compiler's output is meant to look like the platform, and the more successfully it does that, the less there is to fingerprint. What we match is the loader and the component registration pattern the toolchain emits, which is present in a normal build and can be absent from a heavily customised one. The count is therefore a floor.

Presence implies a particular kind of team. Nobody reaches for a web component compiler to build a marketing page. Organisations use one when the same buttons, tables and form controls have to appear in several applications built by different groups on different frameworks, which is a design system problem rather than a website problem. So a domain running Stencil is usually the public face of a larger internal engineering effort, and the interesting entries in the list are frequently documentation portals, developer consoles and enterprise applications rather than shops.

The MIT license and the 2017 release date fill in the commercial picture. Free licensing means adoption leaves no contract trail, so the vendor cannot tell you who uses the compiler and neither can anyone else without measuring the web directly. A toolchain of that age has had time to reach production without being old enough to have accumulated many abandoned installs, so what shows up now is largely deliberate and largely current.

One caveat is worth stating plainly. The word is not unique in web tooling, and at least one storefront theme system uses the same name, so our figure counts matches for the compiler published by Ionic rather than for every product sharing the label. Anyone joining our export against another source should confirm the two are measuring the same thing before treating the numbers as comparable.

As of October 2026 we detect Stencil on 133 sites. A number that size is not a market share statistic and should not be used as one. The value of the list is as a sampling frame, a set of organisations that have committed to shipping framework independent components. That is a strong filter for anyone selling design system tooling, component testing services or developer platform products, and an equally strong one for a researcher trying to measure whether the web components idea took hold outside conference talks.
