Toolbx
What Toolbx is
Toolbx creates interactive Linux command-line environments for software development and host troubleshooting, allowing tools to be installed in containers rather than on the host. Separate `/usr` filesystems help keep project tools apart from the operating system. Built on Podman and OCI container technologies, Toolbx environments can access host resources such as the home directory, networking, display sockets, removable devices, the system journal, SSH agent, and D-Bus. The project regularly tests Arch Linux, Fedora, Red Hat Enterprise Linux 8.5 or later, and Ubuntu as host distributions, and can create environments for Arch, Fedora, RHEL, and Ubuntu. GNOME Builder supports building and testing inside a selected container, while Ptyxis opens containers from an IDE. Toolbx is installed by default on Fedora Silverblue and Workstation; other systems can use a toolbox or podman-toolbox package. It is free Linux software priced at $0 and requires Podman 1.6.4 or later.
Who it suits
It suits Linux developers and administrators who want container-based command-line environments for development or host troubleshooting. GNOME Builder and Ptyxis users can also connect Toolbx environments with desktop development workflows.
What it does well
- Free, open-source Linux software
- Separate `/usr` filesystems reduce host tool conflicts
- Supports Arch, Fedora, RHEL, and Ubuntu environments
- GNOME Builder and IDE integration
- Installed by default on Fedora Silverblue and Workstation
What to know first
- Makes no security promise beyond the host command line
- Host user details are propagated into containers
- SELinux label separation is disabled
- Requires Podman 1.6.4 or later

Verdict
Toolbx separates development tools from the host while retaining access to selected host resources. It fits Linux workflows that need reproducible container environments, but it is explicitly not a secure development environment.
