    Gobuster

    Gobuster

    Directory/File, DNS and VHost busting tool written in Go

    Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime. Provides several modes, like the classic...

    Jaeger

    Jaeger

    Monitor and troubleshoot transactions in complex distributed systems

    As on-the-ground microservice practitioners are quickly realizing, the majority of operational problems that arise when moving to a distributed architecture are ultimately grounded in two areas: networking and observability. It is simply an orders of magnitude larger problem to network and debug a set of intertwined distributed services versus a single monolithic application. Jaeger, inspired by Dapper and OpenZipkin, is a distributed tracing system released as open source by Uber Technologies. It is used for monitoring and troubleshooting microservices-based distributed systems. OpenTracing compatible data model and instrumentation libraries include Go, Java, Node, Python, C++ and C#. Jaeger uses consistent upfront sampling with individual per service/endpoint probabilities and it has multiple storage backends: Cassandra, Elasticsearch, memory.

    Xplorer, a customizable, modern file manager

    Xplorer is a modern, cross-platform file manager built from the ground up to meet contemporary file-browsing needs across Windows, macOS, and Linux.

It supports multiple tabs, allowing users to open and manage many directories simultaneously. A key strength is built-in file preview: beyond just listing files, Xplorer lets you preview many file types directly (images, text files with syntax highlighting, and even video preview for supported formats), saving the extra step of opening external viewers. ...
