11 Best Free and Open Source Linux Debuggers

Last Updated on May 25, 2022

Debugging is the process of finding and reducing the number of bugs in computer software and electronic hardware. When a program crashes, the debugger shows the position in the original code. A good debugger plays an essential role in software development.

Debugging can be more difficult when various subsystems are tightly coupled, as changes in one may cause bugs to appear in another.

This article examines three different types of debuggers: source-level debuggers, memory debuggers and bug tracking software.

A memory debugger is a programming tool for finding memory leaks and buffer overflows. These are due to bugs related to the allocation and deallocation of dynamic memory. Programs written in languages that have garbage collection, such as managed code, might also need memory debuggers.

Bug tracking software helps quality assurance and programmers keep track of reported software bugs in their work.

Here’s our recommendations. They are all free and open source goodness.
