Find the code your fuzzing tests never reach.

What it does

Identifies code missed by fuzzing and guides improvements to harnesses, seed inputs, and dictionaries.

When to use it

Use to establish a fuzzing baseline, investigate stalled or unreachable paths, verify harness changes, compare fuzzers, or identify needed seeds and dictionary entries.

How to use it

Give it a project and its fuzzing corpus; it generates coverage reports and identifies missed paths and possible improvements.
