PRTG Catches Network Issues Before They Cause DowntimeReactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

Bootswatch
Themes for Bootstrap
Bootswatch is a collection of open-source themes for Bootstrap. It helps developers change the look of a Bootstrap project without rebuilding the entire design system from scratch. Each theme works as a drop-in replacement for Bootstrap’s default stylesheet, which makes adoption simple for existing sites. The project supports several installation paths, including precompiled CSS, CDN usage, npm, Sass imports, and Ruby gem integration. Developers can customize themes by editing Sass variables and theme-specific structural styles. Overall, Bootswatch is useful for teams that want polished Bootstrap styling, faster prototyping, and consistent visual options across web projects. -

Cheerio
Implementation of core jQuery designed for the server
Fast, flexible & lean implementation of core jQuery designed specifically for the server. Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API. Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient. Cheerio wraps around parse5 parser and can optionally use @FB55's forgiving htmlparser2. Cheerio can parse nearly any HTML or XML document. Cheerio parses markup and provides an API for traversing/manipulating the resulting data structure. It does not interpret the result as a web browser does. Specifically, it does not produce a visual rendering, apply CSS, load external resources, or execute JavaScript. If your use case requires any of this functionality, you should consider projects like Puppeteer or JSDom. -

Consola
Elegant Console Logger for Node.js and Browser
Fancy output with fallback for minimal environments. Consistent command-line interface (CLI) experience. Spam prevention by throttling logs. console uses std in the underlying so calling wrapStd redirects console too. The benefit of this function is that things like console.info will be correctly redirected to the corresponding type. Any instance of consola that inherits the mocked instance, will apply provided callback again. This way, mocking works for withTag scoped loggers without the need for extra effort. Choose between one of the built-in reporters or bring in your own one. By default FancyReporter is registered for modern terminals or BasicReporter will be used if running in limited environments such as CIs. A reporter (class or object) exposes log(logObj) method. To get more info about how to write your own reporter, take a look at the linked implementations. -

Fabric
Fabric is an open-source framework for augmenting humans using AI
Fabric is a command-line framework that turns a curated library of prompt “patterns” into reusable, automatable workflows for large language models. Instead of repeatedly crafting ad-hoc prompts, you pick a pattern (for research, summarization, brainstorming, code review, and more) and feed it inputs or files. The tool standardizes execution with configuration files and environment variables, enabling reproducible runs across different models and providers. Patterns can be customized with variables, chained into pipelines, and applied to entire directories, which helps scale editorial or analytical tasks. A growing catalog of community patterns serves as a knowledge base for effective prompt engineering in practical contexts. In short, Fabric makes LLM work predictable and scriptable, so teams can share methods rather than one-off prompts. -

Get Shit Done
A light-weight and powerful meta-prompting, context engineering
Get Shit Done is a high-impact, open-source meta-prompting and spec-driven development system designed to streamline building software with AI assistants like Claude Code, OpenCode, and Gemini CLI. It solves “context rot” — the degradation of AI quality as a chat session grows — by structuring your idea into precise, context-engineered steps that are researched, scoped, planned, executed, and verified with clear commands and outputs instead of ad-hoc prompts. The project emphasizes simplicity and effectiveness over bureaucratic workflows like story points, sprint ceremonies, or enterprise processes, making it especially useful for solo developers or small teams aiming to get reliable execution without overhead. GSD breaks down big goals into atomic plans, keeps AI context fresh, and automates task execution while generating standardized documentation, roadmaps, and commit histories. -

Gitrob
Scans GitHub repositories for potentially sensitive files
Gitrob is an open source reconnaissance tool designed to identify potentially sensitive files that have been committed to public GitHub repositories. It helps security professionals, researchers, and organizations detect accidental data exposure by scanning repositories associated with specific GitHub users or organizations. The tool works by cloning repositories and analyzing their commit history to search for files that match predefined signatures of sensitive data. These signatures are used to flag items such as credentials, private keys, configuration files, and other materials that may expose confidential information. By automatically inspecting repository histories, Gitrob simplifies the process of identifying security risks that might otherwise remain unnoticed in publicly accessible codebases. The results of the scan are presented through a built-in web interface that allows users to browse findings, review flagged files, and analyze potential leaks more efficiently. -

IPLD Explorer Components
React components for ipfs-webui
React components for ipfs-webui. This module was extracted from explore.ipld.io so it could be reused from the IPFS Web UI. This module is not intended to be re-used in it's current form by other projects. There is more work to do to make this a nice set of generic components. The ES5-friendly version of the src dir is generated to the dist dir and the page components are all provided as named exports so you can import them. There are peer dependencies so that the parent app can pick the versions of common deps. You'll need to add relevant deps to your project. These components use redux-bundler and your app will need to use a redux-bundler provider in order to propagate the properties and selectors. You can find a basic example of this in ./dev/devPage.jsx. -

Layui UI
An open source Web UI component library
layui is a set of open-source Web UI component library, which adopts its own classic modularization specifications and follows the development method of native HTML/CSS/JS. It is very easy to use and ready to use. Its style is simple and light, while its components are elegant and rich. Every detail from source code to usage method has been carefully crafted, which is very suitable for the rapid development of web interface. Layui is different from those front-end frameworks based on the bottom layer of MVVM, but it does not go against the road, but believes in returning to the basics. To be precise, it is more for back-end developers. You don’t need to get involved in various front-end tools. You only need to face the browser itself, and let all the elements and interactions you need come from here at your fingertips. -

MongoDB NodeJS Driver
The MongoDB Node.js driver
The MongoDB Node.js driver allows Node.js applications to connect to MongoDB and work with data. The driver features an asynchronous API which allows you to interact with MongoDB using Promises or via traditional callbacks. Whether you are new to MongoDB or you just want to brush up on the core concepts, you can check out the Fundamentals section which features material on using the Node.js driver. The connection URI is the set of instructions that the driver uses to connect to a MongoDB deployment. It instructs the driver on how it should connect to MongoDB and how it should behave while connected. The Authentication Mechanisms guide contains sample connection code using each authentication mechanism supported in the MongoDB Community Edition. The Node.js driver uses the asynchronous Javascript API to communicate with your MongoDB cluster. Asynchronous Javascript allows you to execute operations without waiting for the processing thread to become free.
