We measure and record a range of statistics related to ZAP, some of which are made public here.
The blog post: Collecting Statistics for Open Source Projects explains how this all works.
ZAP Starts
The number of News requests ZAP made per month, by version. These are a good approximation of the number of times ZAP was started. Daily/weekly builds are grouped under Daily.These figures come from the News requests that ZAP makes when it starts. Daily and weekly builds are grouped under the Daily label. The News and other ‘calls home’ that ZAP makes are detailed in the FAQ: What ‘calls home’ does ZAP make?
Direct Downloads
Direct downloads since v2.4.3. It is worth noting that downloads have reduced since the Docker images have become more popular.In April 2024 we removed the OWASP images, created a new zaproxy DockerHub org, deprecated the SSP docker images, and started collecting stats for the GHCR image.
