Credits and licences

Our own code
The tools and page layouts are written for this site, except the two libraries listed below. The pages make no requests to other servers: everything, including the libraries, is served from this site and runs in your browser.
Third-party material
Each library’s full licence text ships with it in the site’s source. Facts on the tool pages are taken from the public documentation linked in each page’s Sources line (man pages, Apache HTTP Server, nginx, Docker, Kubernetes, systemd and Quartz documentation, the YAML specification and IETF RFCs).
| Name | Used for | Licence |
|---|---|---|
| yaml 2.9.1 (Eemeli Aro) | Parses and writes YAML in the YAML validator, YAML formatter, docker run to Compose converter, Docker Compose example generator and Kubernetes CronJob generator. Runs in your browser; included unmodified. | ISC |
| bcryptjs 3.0.3 | Computes bcrypt password hashes in the htpasswd generator, in your browser. One line changed so it builds for the browser (it uses the browser's own random numbers); see assets/js/vendor/bcryptjs/README.md. | BSD-3-Clause |
Licence texts
The minified scripts the pages load do not keep the libraries’ comment headers, so the full notices are reproduced here.
