A webserver for hosting scoring services. For more information, see the ORES documentation on MediaWiki.


ORES is based on Python 3. Use pip to install ORES:

pip install ores (or pip3 install ores if your distribution defaults to Python 2)

If you're running with the default Redis configuration, you'll need to install a few more optional libraries,

pip install ores[redis]

Then you can easily run a test server by:

ores applications.wsgi

Use the -h argument to view its usage.

ores applications.wsgi -h

Visit these pages to see if your installation works,

Running ores using docker composer

As an easy way to run ores for development, download and install docker-compose and then do:

docker-compose build && docker-compose up

ores will be accessible through localhost:8080

Running tests

For a native installation, make sure you installed dependencies for testing:

pip install -r test-requirements.txt

then run:

py.test .

For docker installation, run:

docker-compose exec ores-worker py.test /ores


ORES provides several utilities:

  • precached: Starts a daemon that requests scores for revisions as they happen
  • score_revisions: Scores a set of revisions using an ORES API
  • stress_test: Scores a large set of revisions at a configurable rate
  • test_api: Runs a series of tests against a live ORES API

In order to run any of them, run it through ./utility wrapper:

./utility test_api -h

For docker installations run it through one of containers:

docker-compose exec ores-worker /ores/utility test_api -h
