Burp Comparer Documentation

Burp Comparer is a simple tool for performing a comparison (a visual "diff") between any two items of data. Some common uses for Burp Comparer are as follows:

Loading Raw Data

You can load data into Comparer in the following ways:

Performing Comparisons

Each item of loaded data is shown in two identical lists. To perform a comparison, select a different item from each list and click one of the "Compare" buttons:

Note: The byte-level comparison is considerably more computationally intensive, and you should normally only employ this option when a word-level comparison has failed to identify the relevant differences in an informative way.

When you initiate a comparison, a new window appears showing the results of the comparison. The title bar of the window indicates the total number of differences (i.e. edits) between the two items. The two main panels show the compared items colorized to indicate each modification, deletion and addition required to transform the first item into the second.

You can view each item in text or hex form. Selecting the "Sync views" option will enable you to scroll the two panels simultaneously and so quickly identify the interesting edits in most situations.

v1.6.12

This release contains various bugfixes and minor enhancements, including:

  • In the site map table, the "Method" column previously always showed GET for requests without a body, and POST for requests with a body, even if the actual method was different. This bug has now been fixed and the table shows the correct method.
  • A bug which prevented client SSL certificates from being used when an upstream proxy is configured has been fixed.
  • A bug which caused Decoder to fail to decode hex number HTML entities containing an upper-case X has been fixed.
