We just published a new release of our free FuseIT SFDC Explorer. This is purely a developers tool and one we use internally in preference to those offered by others. As well as a range of bug fixes some of the new features are:
- Enables sOject metadata to be viewed
- Extrapolate the server URL from the SessionId using the hive/pod Id
- Upgraded to work with Salesforce Partner API Version 27 (Spring '13)
If you need to get a good look inside Salesforce or have previously uploaded the FuseIT SFDC Explorer, you need the latest release. See more about it here.
