Information about some of the machines serving Perl developers around the world. To suggest updates check out the source.

What kind of information?

This page is (going to be) a collection of information about the hardware and software serving people who are using Perl.

In particular, it should contain information about the following aspects:

  • Hardware - what kind of machines are used to provide the service? (VPS-es would be included here)
  • Who maintains them? Who and how should be contacted in case the service is malfunctioning?
  • What software does the machine run to provide the service?
  • Is the source code of the service available to the public somewhere? (e.g. GitHub repository)
  • Who pays the bills? Is there a sponsor? Someone pays from her/his own pocket?

MetaCPAN, the Open Source search engine of CPAN. It has several sub-projects hosted in the CPAN-API GitHub organization. metacpan-web is the front-end written using Catalyst, and cpan-api is the back-end.

Servers and hosting, donated by Bytemark and Liquid Web. For details see the list of servers.

Everything is deployed via Puppet. Source code is in GitHub.

There are Vagrant development boxes for getting people started. See MetaCPAN developer environment,

Every site sits behind Fastly CDN

Everything is on GitHub

PerlMonks is based on a version of Everything. According to this node a different version of Everything (Everything2) is now open source, but there are some PerlMonks specific things that are not open source.

The website is hosted via three webservers in DNS rotation, with a MySQL backend. The webservers are provided by The domains are provided by TPF and managed by

Strawberry Perl is just a few static pages. GitHub repository

The Webserver:

  • DreamHost webhosting (some pricing plan with unlimited storage)
  • Adam Kennedy pays for the hosting + domain

There is also build server and CPAN smoker:

  • VPS from (Czech Republic)
  • Windows 2012 R2, 80GB HDD/SSD, 16GB RAM, 4 CPUs
  • the cost was approx. 700 USD/year
  • paid by Enlightened Perl Organisation

A couple of GitHub repos.

Perl Dancer, the web framework. The source code of its own web site is in the perldancer-website repository. is itself based on Dancer. Its source code is in the advent-calendar repository.

Both sites run on the server of David Precious. sites

Under the maintenance of Robert and Ask as listed on the (GitHub: authentication service The central site of the Perl Mongers GitHub AnnoCPAN is a service to easily annotate the documentation of CPAN modules.

Perl 6, the main Perl 6 website, consists of static pages generated from perl6/, the Perl 6 documentation site consists of static pages generated from this repository. the list of available Perl 6 modules. Static pages generated by this code. the CPAN Testers from Perl 6. This is a dynamic site. The source code is in this repository.

Perl Tutorial

Maintained by Christian Walde (Mithaldu) and Tina Müller (Tinita). Information about the system can be found in their about page.

Perl News

Maintained by Leo Lapworth (Ranguard), the shared blog site of the Perl community runs on the Professional Edition of Movable Type which is not open source. Though it might be the open source version with a few extra (proprietary) extensions.

Nevertheless the templates of the site are available here. There is also a version of Movable Type on GitHub, but it is unclear to me what is the license of that, and what is the relation of that to the one used on

The site runs on a dedicated server at Hetzner. It is an Intel i7 with four cores (plus hyper-threading), 8 GB of RAM, and software RAID. It's currently running Ubuntu.

The server is maintained by Dave Cross and Aaron Crane. They also cover the expenses.

CPAN Testers

The CPANdeps project run by David Cantrell, has its source code in GitHub. It is on a dedicated server provided for free by It has 4GB RAM, 0.5TB disk, and some species of dual-core processor. It runs Debian Linux, MySQL, Apache and perl.


The site run by David Cantrell, has its source code in GitHub cpXXXan is similar to CPANdeps and also provided for free by The hardware is identical apart from only 2GB of memory. It uses the same software.

Slaven Rezic runs on a small one-CPU VM. Actually this VM is dedicated to another service of Slaven and the matrix is just a guest there. The alternative version of the matrix (the "log.txt" view) runs on another machine setup by Barbie and sponsored by Webfusion (see the banner on that page). A possible task for the QA hackathon would be to move the regular matrix also to this machine, as it is bigger and dedicated to perl QA stuff (IIRC a physical machine with eight CPUs).

The matrix is an old-fashioned CGI running in an old-fashioned Apache server. It's also possible to run it as a PSGI application, but currently there's no pressing need to do so. The software is at GitHub.

CPAN Testers - smokers

David Cantrell: My testing is done in a Linux VM running on a dedicated server that I rent. It nominally has 8GB RAM and 4 CPUs. The underlying hardware has 32GB and 8 CPUs. Virtualisation is done with Xen. Unfortunately I no longer test on any other OSes.

Slaven Rezic: I maintain four regular smokers (two FreeBSD + two Linux, with several perl versions ranging from 5.8.9 to 5.21.10), all running in VMs. Three of them are located on my personal workstation and one is running on a server of another Berlin perl monger. Typically the machines are running 24/7 except when I am on vacation. In these periods the "specialties" of my smokers (that is: provide first reports very quickly after PAUSE upload, and provide reports for a rather rare platform, FreeBSD) have to be done by other people (in this case, by Andreas Koenig and Chris Williams).

The smokers are based on and CPAN::Reporter, but I don't use CPAN::Reporter::Smoker. Instead I have a couple of wrapper scripts (cpan_smoke_modules_wrapper3, cpan_smoke_modules) which may be found on GitHub. There's no real documentation for these, primarily because I doubt that my workflow is appealing to other people.

CPANTS - A CPAN Testing Service

(Unrelated to CPAN Testers above!) check various kwalitee metrics about CPAN modules. The service is maintained by Kenichi Ishigaki (charsbar). The source code of the web-site is in GitHub.

Most Perl conferences (YAPCs, Workshops etc) run on Act - A Conference Toolkit. Its source code is in the Act repository. The server is run by the The French Perl Mongueurs: Sébastien Aperghis-Tramoni (maddingue), Philippe Bruhat (BooK), and Éric Cholet.

In case the service is not available you can ask for help on the #act channel on Specifically you might want to ping maddingue there.

YAPC::EU and are the home page(s) of the YAPC::Europe Foundation. They are also used as the domain for the YAPC::EU events while the actual sites of the events are hosted on the central ACT server.

Philippe Bruhat (BooK): The /$year/ URLs are pointing either to the corresponding Act website, or a static archive of the site. The static data is stored here: (the only missing site is the one for Belfast 2004, but I have it on my todo-list to grab the data from and eventually add it there).

Every URL actually points to Act. The webserver has a complex config canonicalizing URLs back and forth. Some of it handled by Act. For example, and will redirect to

The source code is in GitHub

The actual website is generated by a 15 years old script running ttree.

YAPC and Perl Workshops the domain for YAPC::NA. The actual sites are based on ACT and are hosted on the central ACT server. Is a nice-looking, but outdated site linking to other YAPCs and Perl Workshops. redirects to the ACT instance used to manage YAPC::Russia events. NLPW - Dutch Perl Workshop. DC-Baltimore Perl Workshop. Swiss Perl Workshop. QA Hackathon.


Daisuke Maki (lestrrat): hosts (or at least redirects to) all of the past YAPC::Asia Tokyo's that have been held, dating back to 2006. Up to 2009. The system behind was ACT, so the actual site lived with other YAPCs that it hosts.

Since 2010, YAPC::Asia Tokyo's site's static content has been built using MovableType, and the dynamic content including user registration, payment (only for 2010 and 2011), talk submission and listing have been built using either bare PSGI servers that does the minimum job or a simple Mojolicious based application. Payments are handled by Peatix, Inc since 2012 -- until then we used to use a handmade QR-code solution. There's absolutely no fancy engineering behind them because we did not intend to put resources in the engineering side of the conference.

A single nginx server handles all the frontend marshaling.

In 2015, all the infrastructure has been moved to a Docker based architecture just for the heck of it, but in hindsight this was unnecessary, except for the fact that the yours truly learned a lot about how to use Docker :)

The infrastructure is hosted under Sakura VPS.

Japan Perl Association

Daisuke Maki (lestrrat): the site of Japan Perl Association, doesn't have much content in it, so it's built with a simple Mojolicious application and nginx, running on a VPS at CPI ( Most of what we do under the domain is actual shuffling documents and so forth, so we use Google Apps to to handle this.


Mojolicious, the web framework. The source code of its own web site is in the Mojolicious repository.


Perl Maven The site (along with a few smaller sites of Gabor Szabo) is hosted on Linode instance with 4Gb memory 4 CPUs. It is based on Dancer 2 its source code is available on GitHub. The content is also available on GitHub runs on Baildor, a partially implemented Perl Dancer clone in Perl 6. Its source code is available on GitHub. It is hosted on Linode instance with 2Gb memory 2 CPUs, along with a few other sites of Gabor Szabo.

Perl Weekly is the curated weekly newsletter about Perl. It is hosted on a Linode instance along with a few other domains. Source code is in GitHub
