Dependencies
A rewrite of the old legacy software "depends.exe" in C# for Windows
Dependencies is a rewrite of the legacy software Dependency Walker which was shipped along Windows SDKs, but whose development stopped around 2006. Dependencies can help Windows developers troubleshooting their dll load dependencies issues. Dependencies is currently shipped as two binaries (no installer present) : Dependencies.exe as a CLI tool and DependenciesGui.exe for its GUI counterpart (see screenshot). Just click on one of the release numbers above (preferably the latest), download and uncompress the archive and run DependenciesGui.exe. Since the binary is not signed, SmartScreen might scream at runtime. Dependencies also bundle ClrPhTester.exe, a dumpbin-like executable used to test for non-regressions. Dependencies currently does not recursively resolve child imports when parsing a new PE since it can be really memory-hungry to do so ( it can over a GB even for "simple" PEs ). -

ZAP
The OWASP ZAP core project
The OWASP Zed Attack Proxy (ZAP) is one of the world’s most popular free security tools and is actively maintained by a dedicated international team of volunteers. It can help you automatically find security vulnerabilities in your web applications while you are developing and testing your applications. It's also a great tool for experienced pentesters to use for manual security testing. ZAP is an easy to use integrated penetration testing tool for finding vulnerabilities in web applications. It is designed to be used by people with a wide range of security experience and as such is ideal for developers and functional testers who are new to penetration testing. ZAP provides automated scanners as well as a set of tools that allow you to find security vulnerabilities manually. It stands between the tester’s browser and the web application so that it can intercept and inspect messages sent between browser and web application. -

Reactotron
Desktop app for inspecting your React JS and React Native projects
Reactotron is a macOS, Windows, and Linux app for inspecting your React JS and React Native apps. View your application state, show API requests & responses, perform quick performance benchmarks, subscribe to parts of your application state, display messages similar to console.log, track global errors with source-mapped stack traces including saga stack traces! You can dispatch actions like a government-run mind control experiment, hot swap your app's state using Redux or mobx-state-tree, track your sagas, show image overlay in React Native, track your Async Storage in React Native, etc. You plug it into your app as a dev dependency so it adds nothing to your product builds. Reactotron, as an open source project, is free to use and always will be. -

PerfView
PerfView is a CPU and memory performance-analysis tool
PerfView is a free performance analysis tool that helps isolate CPU and memory-related performance issues. It is a Windows tool, but it also has some support for analyzing data collected on Linux machines. It works for a wide variety of scenarios, but has a number of special features for investigating performance issues in code written for the .NET runtime. If you are unfamiliar with PerfView, there are PerfView video tutorials. Also, Vance Morrison's blog gives an overview and getting started information. PerfView is built on a library called Microsoft.Diagnostics.Tracing.TraceEvent, which knows how to both collect and parse Event Tracing for Windows (ETW) data. Thus if there is any information that PerfView collects and processes that you would like to manipulate yourself programmatically, you would probably be interested in the TraceEvent Library Documentation. -

sysbench
Scriptable database and system performance benchmark
sysbench is a scriptable multi-threaded benchmark tool based on LuaJIT. It is most frequently used for database benchmarks, but can also be used to create arbitrarily complex workloads that do not involve a database server. extensive statistics about rate and latency is available, including latency percentiles and histograms. Low overhead even with thousands of concurrent threads. sysbench is capable of generating and tracking hundreds of millions of events per second. New benchmarks can be easily created by implementing pre-defined hooks in user-provided Lua scripts. Can be used as a general-purpose Lua interpreter as well, simply replace #!/usr/bin/lua with #!/usr/bin/sysbench in your script. Execute events for this many seconds with statistics disabled before the actual benchmark run with statistics enabled. This is useful when you want to exclude the initial period of a benchmark run from statistics. -

Zerocopy
Zerocopy makes zero-cost memory manipulation effortless
Zerocopy is a Rust library designed to make zero-cost memory manipulation both safe and effortless. It allows developers to reinterpret or convert raw byte sequences into structured types—and vice versa—without writing unsafe code directly. The crate provides safe abstractions for transmuting data while preserving Rust’s strict safety guarantees, removing the need for manual memory manipulation. Zerocopy introduces a suite of conversion traits such as TryFromBytes, FromBytes, IntoBytes, and FromZeros for defining how types can be safely constructed from or written to byte sequences. It also includes marker traits like KnownLayout, Immutable, and Unaligned to define type characteristics used in conversions. Complementing these traits are conversion macros that perform compile-time checks to ensure size and alignment safety, providing zero runtime overhead for unconditional casts. -

pipx
Install and run Python applications in isolated environments
pipx is a tool to help you install and run end-user applications written in Python. It's roughly similar to macOS's brew, JavaScript's npx, and Linux's apt. It's closely related to pip. In fact, it uses pip, but is focused on installing and managing Python packages that can be run from the command line directly as applications. pip is a general-purpose package installer for both libraries and apps with no environment isolation. pipx is made specifically for application installation, as it adds isolation yet still makes the apps available in your shell: pipx creates an isolated environment for each application and its associated packages. pipx does not ship with pip, but installing it is often an important part of bootstrapping your system. By default, pipx uses the same package index as pip, PyPI. pipx can also install from all other sources pip can, such as a local directory, wheel, git url, etc. -

Ethr
Ethr is a comprehensive network measurement tool for TCP, UDP & ICMP
Ethr is a cross-platform network performance measurement tool written in golang. The goal of this project is to provide a native tool for comprehensive network performance measurements of bandwidth, connections/s, packets/s, latency, loss & jitter, across multiple protocols such as TCP, UDP, HTTP, HTTPS, and across multiple platforms such as Windows, Linux and other Unix systems. Ethr takes inspiration from existing open-source network performance tools and builds upon those ideas. For Bandwidth measurement, it is similar to iPerf3, for TCP & UDP traffic. iPerf3 has many more options for doing such as throttled testing, richer feature set, while Ethr has support for multiple threads, which allows it to scale to 1024 or even higher number of connections, multiple clients communication to a single server etc. For latency measurements, it is similar to latte on Windows or sockperf on Linux. -

Karate
Test automation made simple
Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Assertions and HTML reports are built-in, and you can run tests in parallel for speed. There’s also a cross-platform stand-alone executable for teams not comfortable with Java. You don’t have to compile code. Just write tests in a simple, readable syntax, carefully designed for HTTP, JSON, GraphQL and XML. And you can mix API and UI test-automation within the same test script. A Java API also exists for those who prefer to programmatically integrate Karate’s rich automation and data-assertion capabilities. It is worth pointing out that JSON is a ‘first class citizen’ of the syntax such that you can express payload and expected data without having to use double-quotes and without having to enclose JSON field names in quotes. -

LazyLoad
LazyLoad is a lightweight, flexible script that speeds up your website
LazyLoad is a fast, lightweight and flexible script that speeds up your web application by loading images only as they enter the viewport. LazyLoad supports responsive images. LazyLoad is a lightweight (2.4 kB) and flexible script that speeds up your web application by deferring the loading of your below-the-fold images, animated SVGs, videos and iframes to when they will enter the viewport. It’s written in plain “vanilla” JavaScript, it leverages the IntersectionObserver API, it supports responsive images, it optimizes your website for slower connections, and can enable native lazy loading. To display content images on your pages, always use the img tag. This would benefit the SEO and the accessibility of your website. To understand if your images are content or background, ask yourself: “would my website user like to see those images when printing out the page?”. If the answer is “yes”, then your images are content images and you should avoid using background images to display them. -

"Slow CPU" Emulator
Slows down any given Windows process (written in C#)
"Slow CPU" Emulator is useful for slowing down games, testing how applications deal with lag, and/or reducing the overall CPU usage of a specified process. Simply tell the emulator the update interval and speed percentage, and witness your application slowing down to the specified speed live! The code is written in C# for Windows and is extremely robust, flexible and stable, and has been tested very thoroughly. I apologise in advance for the code not being very readable, sometimes spaghetti code is more optimised code. ;) If you encounter any issues, do not hesitate to tell me. :) License: MS-PL Do whatever you want with the code. Credit would be nice, but definitely not required. I am not responsible for any undesired or unintended effects that may (most probably won't) come up as a result of using the application. -
