The software is implemented as pyramid web app based on the clld toolkit.


To get WALS Online running locally, you need python 2.7 and have to run your system's equivalent to the following bash commands:

virtualenv --no-site-packages wals
cd wals/
. bin/activate
curl -O
python clld-wals3-d23d403/
cd wals3/
pip install -r requirements.txt
python develop
python wals3/scripts/ sqlite.ini
pserve sqlite.ini

Then you should be able to access the application by visiting http://localhost:6543 in your browser. Note that you still need an internet connection for the application to download external resources like the map tiles or javascript libraries.
