How do we count contributing developers?

In all cases, Snyk counts contributors per integration. When counting contributors, we only count:  

• Users who contributed at least one commit to the default branch for any of the repos during the last 90 days. 
• Contributors to the default branch of the private repos in the integration.
• We do not count contributors for public (open source) repos currently, as our pricing model is based on the number of contributing developers per private repository.
• Our count is based on the unique number of local environment Git email addresses. Alternatively, if the email cannot be retrieved for any reason, then we count the Git services user name instead. This is the same information that can be retrieved with git log.
