2.0.0 with basic TUI (terminal/console user interface)

• New terminal interface: An optional terminal version lets you browse devices, search, view system information, and inspect device properties without opening a graphical window. It used FINAL CUT, a C++ library for creating terminal-based applications (TUI) with text-based widgets.
• Export your device tree: Save the device list as a text file or a web page with expandable branches, making it easier to share your hardware setup.
• Clearer device organization: All Devices now groups related hardware entries into expandable branches, with clearer names for network interfaces, sound cards, and graphics functions. Firmware-controlled devices are also grouped beneath their recorded parents.
• More reliable connection trees: Devices stay beneath their hardware ancestors even when intermediate entries are missing. UEFI firmware variables have their own clearly labeled group.
• Open the most useful details first: Device properties automatically open the first relevant tab, such as USB for a USB hub. UEFI firmware variables open directly to their hex dump. Your tab choice is preserved when reloading properties.
• Keep your place after searching: Clearing the search keeps the device you selected in the results selected and brings it into view.

Full Changelog: v1.4.1...v2.0.0

Hotfix 1.4.1

The previous version was bugged, this release fixes broken (not totally - it just took half a minute) RAM tabs switching.

Version 1.4.0 changelog:

• Richer processor information: View core groups, maximum frequencies, performance and efficiency cores where reported, SMT/Hyper-Threading status, and how caches are shared. A dedicated Copy button copies the supported instruction sets and CPU features.
• Wi-Fi connection details: The Network tab now shows the connected network name, operating mode, channels, channel widths, signal strength, transmit power, link rates, and security information. Availability depends on your driver, network service, and permissions; some details require administrator access.
• Bluetooth information: Inspect controller identity, version, address, capabilities, radio blocking, and supported services. See devices currently known to the system and their connection, pairing, trust, and blocking status. This is a read-only snapshot, not a complete pairing history.
• Audio devices information: Find out the PulseAudio server version, audio codec, audio profiles, ports, playback and recording sinks.
• Clearer drive health reports: ATA SMART attributes now have more readable names, durations, and units. Read/write totals can use smartmontools when installed and permitted, with clearer warnings when values are uncertain or access is restricted.
• Optional GPU PCIe link test: Run a short graphics workload to observe whether a selected GPU's PCIe speed or lane width increases under load. The test is offered when usable link readings are available; it is not a graphics performance benchmark.
• Easier-to-read RAM information: Firmware-reported memory devices now have individual chip tabs, making long reports easier to browse.
• Improved information tables: Resize columns manually and read full tables using the page's scrollbars, without separate scrollbars inside each table.
• Volume details on demand: Open a selected storage volume's details with a button or by double-clicking its row.
• More useful device names: Many previously generic system devices now have recognizable names, including firmware-controlled functions and the PC speaker. Device and storage lists also sort numbered names naturally, so item 2 comes before item 10.
• Display improvements: Monitor information now includes an estimated pixel density (PPI). Display outputs are matched more reliably on X11 when connector names differ, and unresponsive display queries have time limits.
• More convenient copying: Copy the current System Information tab or the entire report to the clipboard.

1.3.0 semi-complete

Full Changelog: v1.2.0...v1.3.0

• Full SMART report for devices (the previous version only showed a couple of attributes)
• Reorganized the System Information Dialog
• Add support for Resizable BAR status
• Shows a mostly useless progress bar on start-up (it's near impossible to estimate how long it will take to enumerate the resources)

1.2.0 even more information

Full Changelog: v1.1.0...v1.2.0

Adds a lot more information:

• Ethernet adaptors link speed, duplex, autonegotiation and modes
• PCIe devices current link speed/width, reported device maximum speed/width, and connection type when running as root
• Web cameras codecs, resolutions and refresh rates
• Monitor vendor, model, product code, serial number and dimensions in centimeters.

1.1.0 with more information

Full Changelog: v1.0.0...v1.1.0

• Now showing network interfaces IP addresses/netmasks/MAC addresses and fake/reassigned MAC addresses
• Shows Display Outputs configuration including resolution, refresh rate, bit depth, rotation, mirroring, scaling (where available) both under X11 and Wayland
• Shows USB devices advanced properties including voltage, USB standard revision and connection speed
• Multiple UI fixes and bugs fixed in line with Windows Device Manager

Version 1.0.0

Full Changelog: v0.9-beta...v1.0.0

Refer to README for the features.

The AppImage was built on Ubuntu 24.04 and it only supports Linux distros released after it.

0.9 BETA

The first public release.

Intended for no one obviously.

Working fine here on my Fedora 44.
