Xcapture-BPF – like Linux top, but with Xray vision
Always on Profiling for Production Systems
Xcapture-BPF – like Linux top, but with Xray vision launched on July 3, 2024 with 447 votes, #85 of 5,184 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
Xcapture-BPF is a Linux system monitoring tool that functions similarly to the standard top command but provides deeper visibility into system processes. It uses eBPF technology to capture detailed performance data that traditional tools cannot see. The tool is designed for developers and system administrators who need advanced insight into what their Linux systems are doing beyond basic resource usage metrics.

From the sources
0x.tools ( GitHub ) is a set of open-source utilities for analyzing application performance on Linux. It has a goal of deployment simplicity and minimal dependencies, to reduce friction of systematic troubleshooting. No need to install kernel modules or heavy monitoring frameworks. 0x.tools allow you to measure individual thread level activity, like executed code, sleep states, system calls and wait locations - by tracking (not tracing) and then sampling the right events at the right time. xtop is like the Linux top tool, but extended with x-ray vision and ability to view your performance data from any chosen angle (that eBPF allows to instrument). This enables dimensional performance…from 0x.tools

XCapture v3: Linux Performance Analysis with Modern eBPF and DuckDB2025 · tanelpoder.com · ▲6Hello, I just released the (eventually) final version of my xcapture eBPF performance tool that now uses modern eBPF (libbpf, BTF, CO-RE, passive sampling using task iterators, task-local storage, etc). The previous BCC-based v2 version got a good discussion here last year [1], but due to BCC being less flexible and now deprecated, I decided to pull the plug and start from scratch with the latest eBPF features available. I'm targeting Linux kernels 5.14 and up. So Ubuntu 20 with HWE kernel (5.15) already works, RHEL9 works, Oracle's RHEL8 clone OEL8 with Oracle's UEK7 kernel (5.15) also…

Uscope, a new Linux debugger written from scratch2025 · github.com · ▲262Hi! I've been building a debugger on my nights and weekends because it's fun, and I personally need a better debugger for my work. GDB and LLDB pain me greatly; we can and will do better! As explained in the README, it's still very early-days and it's not ready for use yet, but check back often because it's improving all the time! Check out https://calabro.io/uscope for a more detailed explanation. Thanks for taking a look!

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
