Data and experiments

Nimbus

Nimbus is Firefox's cross-platform experimentation tool.

You can learn more about Nimbus at https://experimenter.info.

Jetstream analyzes Nimbus experiments. Results appear in Experimenter.

Nimbus experiments are represented in telemetry the same way Normandy experiments are.

Normandy

Normandy is an experimentation platform for Firefox desktop.

Jetstream also analyzes Normandy experiments, although the results do not appear in the experiment console.

Normandy experiments are represented in telemetry the same way Nimbus experiments are.

Heartbeat

Heartbeat is a survey mechanism controlled with Normandy.

Monitoring

We publish aggregate datasets for experiment monitoring to BigQuery.

Experiment-specific telemetry

Sometimes experiments deploy custom telemetry that is not well-documented elsewhere. We maintain a list of these datasets.
