`pwndbg` (/paʊnˈdiˌbʌɡ/) is a GDB plug-in that makes debugging with GDB suck less, with a focus on features needed by low-level software developers, hardware hackers, reverse-engineers and exploit developers.
It has a boatload of features, see [FEATURES.md](FEATURES.md) and [CHEATSHEET](https://drive.google.com/file/d/16t9MV8KTFXK7oX_CzXhmDdaVnjT8IYM4/view?usp=drive_link) (feel free to print it!).
## Why?
Vanilla GDB is terrible to use for reverse engineering and exploit development. Typing `x/g30x $esp` is not fun, and does not confer much information. The year is 2024 and GDB still lacks a real hexdump command! GDB's syntax is arcane and difficult to approach. Windbg users are completely lost when they occasionally need to bump into GDB.
## What?
Pwndbg is a Python module which is loaded directly into GDB, and provides a suite of utilities and crutches to hack around all of the cruft that is GDB and smooth out the rough edges.
Many other projects from the past (e.g., [gdbinit][gdbinit], [PEDA][PEDA]) and present (e.g. [GEF][GEF]) exist to fill some these gaps. Each provides an excellent experience and great features -- but they're difficult to extend (some are unmaintained, and all are a single [100KB][gdbinit2], [200KB][peda.py], or [363KB][gef.py] file (respectively)).
Pwndbg exists not only to replace all of its predecessors, but also to have a clean implementation that runs quickly and is resilient against all the weird corner cases that come up. It also comes batteries-included, so all of its features are available if you run `setup.sh`.

[PEDA]: https://github.com/longld/peda

## How?
For a portable version with no external dependencies, scroll down for the [Portable Installation](#portable-installation) section.
Installation from source is straightforward:
```shell
git clone https://github.com/pwndbg/pwndbg
cd pwndbg
./setup.sh
```
Or install via the Nix package manager (you can use Nix on any distribution):
```shell
nix shell github:pwndbg/pwndbg
pwndbg ./your-binary
```
Pwndbg is supported on Ubuntu 22.04, and 24.04 with GDB 12.1 and later. We do not test on any older versions of Ubuntu, so `pwndbg` may not work on these versions.
- For Ubuntu 20.04 use the [2024.08.29 release](https://github.com/pwndbg/pwndbg/releases/tag/2024.08.29)
- For Ubuntu 18.04 use the [2023.07.17: ubuntu18.04-final release](https://github.com/pwndbg/pwndbg/releases/tag/2023.07.17)
We may accept pull requests fixing issues in older versions on a case by case basis, please discuss this with us on [Discord](https://discord.gg/x47DssnGwm) first. You can also always checkout an older version of `pwndbg` from around the time the Ubuntu version you're interested in was still supported by Canonical, or you can attempt to build a newer version of GDB from source.
Other Linux distributions are also supported via `setup.sh`, including:
* Debian-based OSes (via apt-get)
* Fedora and Red Hat (via dnf)
* Clear (via swiped)
* OpenSUSE LEAP (via zypper)
* Arch and Manjaro (via community AUR packages)
* Void (via xbps)
* Gentoo (via emerge)
If you use any Linux distribution other than Ubuntu, we recommend using the [latest available GDB](https://www.gnu.org/software/gdb/download/) built from source. You can build it as:
```
cd
mkdir build && cd build
sudo apt install libgmp-dev libmpfr-dev libreadline-dev texinfo # required by build
../configure --disable-nls --disable-werror --with-system-readline --with-python=`which python3` --with-system-gdbinit=/etc/gdb/gdbinit --enable-targets=all
make -j7
```
## Portable Installation:
The portable version includes all necessary dependencies and should work without the need to install additional packages.
### Download the Portable Version:
Download the portable version from the [Pwndbg releases page](https://github.com/pwndbg/pwndbg/releases) by selecting the desired version.
Choose the appropriate version for your system architecture (x86_64, armv7l, aarch64, riscv64).
### Installation on RPM-based Systems (CentOS/Alma/Rocky/RHEL):
```shell
dnf install ./pwndbg-2024.08.29.x86_64.rpm
# pwndbg
```
### Installation on DEB-based Systems (Debian/Ubuntu/Kali):
```shell
apt install ./pwndbg_2024.08.29_amd64.deb
# pwndbg
```
### Installation on Alpine:
```shell
apk add --allow-untrusted ./pwndbg_2024.08.29_x86_64.apk
# pwndbg
```
### Installation on Arch Linux:
```shell
pacman -U ./pwndbg-2024.08.29-1-x86_64.pkg.tar.zst
# pwndbg
```
### Generic Linux Installation:
```shell
tar -v -xf ./pwndbg_2024.08.29_amd64.tar.xz
# ./pwndbg/bin/pwndbg
```
