- the Perl web framework Mojolicious. All hail the hypnotoad!
- Twitter bootstrap to look not too ugly
- some Perl modules and Mojolicious plugins
- Aglio to build the API page
- Hugo to generate this site, using Creative Theme as a basis
- the ebooks of the #Pulp collection from the french editor Walrus to refresh my brain after coding. The versions of Erco are named after the titles of those ebooks. Special thanks to Neil Jomunsi, which allowed the use of the Walrus’s orange monsters as Erco mascot.
