Octocatalog-diff is a tool to detect and display differences in Puppet catalogs compiled from different environments. The catalogs may be obtained through any of the following means: - Compilation using a local puppet instance - Puppet master 3.x/4.x HTTP API - PuppetDB HTTP API - Precompiled JSON catalogs

octocatalog-diff filters out attributes or resources with no effect (e.g. tags) and displays only state differences between the two catalogs. It does not require a working Puppet master (or puppetserver), making it suitable for development use and use in Continuous Integration environments.
