Salesforce Workbench
Workbench in Salesforce Workbench is a powerful, web-based suite of tools designed for administrators and developers to interact with Salesforce.com organizations via the Force.com APIs. Workbench provides robust support for Force.com partner, Bulk, Rest, Streaming, Metadata and Apex API's that allows users to Describe, Query, Manipulate and Migrate both data and metadata in Salesforce. It works on a simple web-browser with a simple user interface. It provides many advanced features for testing and troubleshooting the Force.com API's like customizable SOAP headers, debug logs for API traffic, backward compatibility testing with previous API versions and Single-Sign-on integration with Salesforce applications. Main point to note here is that " Workbench is not an official Salesforce product and its free to use on web ". Even if you raise a case with Salesforce on any Workbench issues, then Salesforce support would not be provided to you at any cost....
