Factor is a concatenative programming language. Factor is innovative, expressive, fast, and has a full-featured library. Factor applications are portable and the Factor implementation runs on all common platforms. Factor can deploy stand-alone applications on all platforms. Full source code is available under the BSD license.

Binaries are built by the build farm. If you intend to track Factor development or contribute to Factor itself, you should build from source instead. Software archaeologists might be interested in historical Factor releases.
Factor is under intense development by a core team of developers working on the language implementation full-time, as well as a number of contributors. The Factor web server and framework powers factorcode.org and concatenative.org.
