Licences

Read from composer.lock and package-lock.json when this page was served. Those files last changed on 29 July 2026.

Two different things are listed on this page, and mixing them up is the usual mistake. The first is the monitoring engine we publish, which you are free to take. The second is the set of libraries the hosted service runs on, which we did not write and whose authors are owed a mention.

1. The UptimeEZ engine, MIT licensed

The engine that runs the checks is published under the MIT licence at github.com/coeurduweb/uptimeez. You may use it, modify it, redistribute it and sell it, commercially included, on one condition: the notice below travels with it.

The engine itself has no third party code in it. There is no composer.json in its repository and no vendor directory: nothing to install, nothing to audit, nobody else to credit. That was a design constraint rather than an accident, because the engine has to run on the shared hosting the sites it watches already live on. It is also the reason this section is four paragraphs long and the next one is two hundred names.

2. What the hosted service runs on

The site you are reading, the customer accounts, the billing and the back office are a Laravel application. It is not the engine, it is not MIT, and it is not published. It does stand on 202 third party libraries: 192 PHP packages that run on the server, and 10 JavaScript packages whose code is sent to your browser. Build tools and test tools are deliberately left out, because their code never reaches you.

No package under a network copyleft licence, checked against both lock files as this page was served. That family is the one that matters for a hosted service: it would require publishing the source of the whole application, and this page would say so rather than let anyone find out later.

3. Every package, by licence

The full list, folded so it does not bury the rest of the page. Each name links to its public record, where the licence we state can be checked against the one its author declares.

6 of the packages below are named by their library only, without the publisher segment of their identifier, because we do not print another product name on our own pages. Nothing is left out of the counts above: they are still counted, still classed under their licence, still shown with their version, and their link is a search on that name rather than a package page. Their full identifiers are in composer.lock inside the deployed build, next to each licence text in the vendor directory, which is where a licence requires the notice to travel.

4. Fonts, icons and the rest

The typeface is Poppins, by Indian Type Foundry and Jonny Pinhorn, under the SIL Open Font License 1.1. It is served from our own server rather than from Google Fonts, which is a privacy decision before it is a speed one: a monitoring tool that needs a third party to render its own pages argues against itself. The licence text travels with the files at openfontlicense.org. The logo, the brand name UptimeEZ, the copy and the screenshots on this site are ours and are not covered by any of the licences above.

5. If we got one wrong

This page states what each author declares in their own package metadata, which is the best source available and not an audit. If you are the author of something listed here and the attribution is wrong, write to support@uptimeez.com and it gets fixed at the source, in the file the page reads, rather than patched on the page.
