    Axe

    Axe

    Logger-agnostic wrapper that normalizes logs regardless of arg style

    Logger-agnostic wrapper that normalizes logs regardless of arg style. Great for large dev teams, old/new projects, and works w/Pino, Bunyan, Winston, console, and more. It is lightweight, performant, highly-configurable, and automatically adds OS, CPU, and Git information to your logs. Hooks, dot-notation remap, omit, and pick of metadata. Axe was built to provide consistency among development teams when it comes to logging. You not only have to worry about your development team using the same approach to writing logs and debugging applications, but you also have to consider that open-source maintainers implement logging differently in their packages. No matter how your team or underlying package style arguments when invoked with logger methods, Axe will clean it up and normalize it for you. This is especially helpful as you can see outliers much more easily in your logging dashboards, and pinpoint where in your application you need to do a better job of logging at.

    Hacklock

    Hacklock

    Hack Android Pattern From Termux With This Tool

    Hacklock is a Bash-based Termux project designed to imitate an Android pattern-lock interface and capture the pattern entered into it. The repository describes the workflow as phishing rather than as direct exploitation of Android's lock-screen security. It claims to work from both rooted and non-rooted Android devices because the collection mechanism is delivered through a web-style lure rather than a device privilege escalation. The project includes support for exposing the imitation page through tunneling services and displaying the captured pattern in a numbered representation. Its interface also includes update, information, and exit functions. The tool is suitable only for controlled awareness testing or research with explicit authorization because using it to obtain another person's unlock pattern would be credential theft.

    MCP Toolbox for Databases

    MCP Toolbox for Databases

    Open source MCP server that exposes database tools for AI agents

    GenAI Toolbox, also known as MCP Toolbox for Databases, is an open source server designed to simplify how generative AI applications interact with databases. It provides a central service that exposes database operations as reusable tools that can be consumed by AI agents and developer workflows. It handles common infrastructure concerns such as authentication, connection pooling, and performance optimization so developers do not have to implement them individually in each application. By defining tools and data sources through configuration files, developers can standardize how AI systems access and operate on database resources. GenAI Toolbox is designed to integrate with agent frameworks and development environments so that AI assistants can execute database-related tasks with proper context and security. It also supports observability through built-in metrics and tracing capabilities, allowing developers to monitor how tools are used and debug interactions.

    Mocha

    Mocha

    A feature-rich JavaScript test framework running on Node.js

    Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. Mocha tests run serially, allowing for flexible and accurate reporting, while mapping uncaught exceptions to the correct test cases. Hosted on GitHub. Mocha runs in the browser. Every release of Mocha will have new builds of ./mocha.js and ./mocha.css for use in the browser. Mocha is the most-depended-upon module on npm and Mocha is an independent open-source project, maintained exclusively by volunteers. Given Mocha’s use of function expressions to define suites and test cases, it’s straightforward to generate your tests dynamically. No special syntax is required — plain ol’ JavaScript can be used to achieve functionality similar to “parameterized” tests, which you may have seen in other frameworks.

    Open Source Text to CAD Harness

    Open Source Text to CAD Harness

    An open source harness for generating CAD models

    Open Source Text to CAD Harness is an open-source framework that enables the generation of parametric 3D CAD models using natural language prompts interpreted by AI coding agents. It acts as a harness that converts text descriptions into source-controlled CAD scripts, which are then compiled into geometric models using tools like OpenCascade and build123d. The system emphasizes reproducibility by storing CAD logic as editable code rather than opaque binary files, allowing iterative refinement through agent-driven workflows. It includes a local visualization interface called CAD Explorer for inspecting generated geometry and supports multiple export formats for engineering and manufacturing use. The project also integrates modular “skills” for robotics, motion planning, and manufacturing validation, making it highly extensible. Designed to run locally without backend dependencies, it provides a flexible environment for experimentation and production workflows.

    SQLite compiled to JavaScript

    SQLite compiled to JavaScript

    A javascript library to run SQLite on the web

    sql.js is a javascript SQL database. It allows you to create a relational database and query it entirely in the browser. You can try it in this online demo. It uses a virtual database file stored in memory, and thus doesn't persist the changes made to the database. However, it allows you to import any existing sqlite file, and to export the created database as a JavaScript typed array. sql.js uses emscripten to compile SQLite to webassembly (or to javascript code for compatibility with older browsers). It includes contributed math and string extension functions. sql.js can be used like any traditional JavaScript library. If you are building a native application in JavaScript (using Electron for instance), or are working in node.js, you will likely prefer to use a native binding of SQLite to JavaScript. A native binding will not only be faster because it will run native code, but it will also be able to work on database files directly instead of having to load the entire database.
