Seeker
Accurately Locate Smartphones using Social Engineering
Seeker is an open source project that demonstrates how to obtain precise location information from devices using social engineering and web-based techniques. The tool sets up a phishing page that asks for location permissions, allowing GPS and other device data to be shared if the user consents. It can capture latitude, longitude, accuracy, altitude, direction, and even speed, with results displayed in a terminal. The project supports both manual deployment and tunneling services like Ngrok for external access. While primarily intended as an educational resource on security awareness, it highlights the risks of exposing geolocation data online. Its simplicity and effectiveness have made it a popular project in cybersecurity learning circles. -

Point Cloud Library
A standalone, large scale, open project for 2D/3D image processing
The Point Cloud Library (PCL) is a standalone, large scale, open project for 2D/3D image and point cloud processing. PCL is released under the terms of the BSD license, and thus free for commercial and research use. Whether you’ve just discovered PCL or you’re a long time veteran, this page contains links to a set of resources that will help consolidate your knowledge on PCL and 3D processing. An additional Wiki resource for developers is available too. To simplify both usage and development, we split PCL into a series of modular libraries. PCL is cross-platform, and has been successfully compiled and deployed on Linux, MacOS, Windows, and Android. To simplify development, PCL is split into a series of smaller code libraries, that can be compiled separately. This modularity is important for distributing PCL on platforms with reduced computational or size constraints. -

Look4Sat
Open-source satellite tracker and pass predictor for Android
Track satellite passes with ease. Thanks to the huge database provided by Celestrak and SatNOGS you have access to more than 5000 active satellites orbiting Earth. You can search the entire DB by satellite name or by NORAD catnum. Satellite positions and passes are calculated relative to your location. To get reliable info make sure to set the observation position using GPS or QTH Locator in the Settings menu. The application is built using Kotlin, Coroutines, Architecture Components and Jetpack Navigation. It is now and always will be completely ad-free and open-source. -

OpenBot
OpenBot leverages smartphones as brains for low-cost robots
OpenBot leverages smartphones as brains for low-cost robots. We have designed a small electric vehicle that costs about $50 and serves as a robot body. Our software stack for Android smartphones supports advanced robotics workloads such as person following and real-time autonomous navigation. Current robots are either expensive or make significant compromises on sensory richness, computational power, and communication capabilities. We propose to leverage smartphones to equip robots with extensive sensor suites, powerful computational abilities, state-of-the-art communication channels, and access to a thriving software ecosystem. We design a small electric vehicle that costs $50 and serves as a robot body for standard Android smartphones. We develop a software stack that allows smartphones to use this body for mobile operation and demonstrate that the system is sufficiently powerful to support advanced robotics workloads such as person following and real-time autonomous navigation. -

Translate Shell
Command-line translator using Google Translate, Bing Translator, etc.
Translate Shell (formerly Google Translate CLI) is a command-line translator powered by Google Translate (default), Bing Translator, Yandex.Translate, and Apertium. It gives you easy access to one of these translation engines in your terminal. By default, translations with detailed explanations are shown. You can also translate the text briefly (only the most relevant translation will be shown). Translate Shell can also be used like an interactive shell; input the text to be translated line by line. Translate Shell is known to work on many POSIX-compliant systems. You may use Translate Shell from any Unix shell of your choice (bash, zsh, ksh, tcsh, fish, etc.); however, the wrapper script requires either bash or zsh installed. It is a must to have corresponding fonts for the language(s) / script(s) you wish to display in your terminal. -

J2ObjC
A Java to iOS Objective-C translation tool and runtime
J2ObjC is an open-source command-line tool from Google that translates Java source code to Objective-C for the iOS (iPhone/iPad) platform. This tool enables Java source to be part of an iOS application's build, as no editing of the generated files is necessary. The goal is to write an app's non-UI code (such as application logic and data models) in Java, which is then shared by web apps (using GWT), Android apps, and iOS apps. J2ObjC supports most Java language and runtime features required by client-side application developers, including exceptions, inner and anonymous classes, generic types, threads and reflection. JUnit test translation and execution is also supported. J2ObjC cannot convert Android binary applications. Developers must have source code for their Android app, which they either own or are licensed to use. -

Mapbox GL JS
Interactive, thoroughly customizable maps in the browser
Mapbox GL JS is a JavaScript library that uses WebGL to render interactive maps from vector tiles and Mapbox styles. It is part of the Mapbox GL ecosystem, which includes Mapbox Mobile, a compatible renderer written in C++ with bindings for desktop and mobile platforms. Mapbox GL JS is part of the cross-platform Mapbox GL ecosystem, which also includes compatible native SDKs for applications on Android, iOS, macOS, Qt, and React Native. Mapbox provides building blocks to add location features like maps, search, and navigation into any experience you create. To get started with GL JS or any of our other building blocks, sign up for a Mapbox account. In addition to GL JS, this repository contains code, issues, and test fixtures that are common to both GL JS and the native SDKs. Mapbox GL JS v2 enables 3D mapping with elevated terrain, customizable skies and atmospheric lighting, a new camera, and performance enhancements. -

Th3inspector
Best Tool For Information Gathering
Th3Inspector is a Perl- and shell-based, all-in-one information-gathering toolkit built to quickly enumerate public and semi-public data about targets (domains, IPs, phone numbers, mail servers, etc.). It exposes a single command-line entrypoint (Th3inspector.pl) with many switches for common reconnaissance tasks — examples include website info, whois, MX lookup, geo-IP, subdomain discovery, CMS detection, port scanning, and Cloudflare real-IP resolution — so a user can chain many checks from one script. The project provides simple install wrappers for Linux, Android/Termux and even instructions for Windows (Perl + CPAN modules), and includes helper scripts to update or install dependencies automatically. The repository is actively packaged as versioned releases in the README (current noted version 1.9) and is distributed under an MIT license. -
