Try tracking feature/bug updates in Jira and use it to track what stage of the process it's in and who is currently responsible for it.
You can also try Github, but issue tracking there doesn't have as many features as Jira.
You can also try zube.io with github issues and link all code changes in the repos to tickets with a clear process that product/design approves all changes on stage before it goes to production. If you need to enforce environment configs on production there are tools for tracking changes that depend on your infrastructure provider.
