PatchMon
Linux Patch Monitoring Automation Platform
PatchMon is a centralized patch monitoring and management platform aimed at simplifying how administrators observe and manage package updates across diverse Linux server environments. It centralizes patch status information from many hosts into a single dashboard where users can view inventories of outdated packages, track repositories per host, and organize machines into logical groups for easier oversight. Agents installed on each server make outbound-only connections to the PatchMon server, improving security by avoiding open inbound ports, while the server side provides role-based access control, user management, and a REST API for integrations. PatchMon also supports a customizable dashboard, detailed per-host metrics, and one-line installers for quick self-hosted deployment, making it suitable for both small clusters and larger fleets. -

Pendulum Editor
A simple markdown editor for static files (Hugo, Nexo, Jekyll
A simple editor for markdown/txt files. Supports saving changes into git repositories hosted anywhere (git add, git commit). Docker images and built binaries are provided. Written by @TitPetric and licensed under the permissive WTFPL. As you write or scroll either the text area or the preview pane, the scroll positions are synchronized based on percentage. In the case of images in the text, accuracy can be quite off, but it's possible to improve this behavior in the future. Most of the development is basically related to the preview of whatever it is you're editing. The editor itself doesn't care about anything other than the contents of the text file you're opening and trying to save. -

Playback
Video player built using electron and node.js
playback is another project by the same author, aimed at simplifying media playback of streaming sources in JavaScript/Node.js contexts. The goal of Playback is to act as a thin wrapper or abstraction layer that eases the task of launching and controlling a media player from code or CLI, perhaps integrating with torrent-based streaming (e.g. from peerflix) or other streaming sources. The library provides programmatic controls over launching playback, passing custom options or arguments, and managing process lifecycle — making it useful for scripts, automation, or tooling where you need to play media without manually wiring up system calls. Playback can be especially handy when building applications that need to fetch media dynamically (from network, torrent, or remote URL) and immediately play it, without requiring the user to manually download, open, and configure a media player themselves. -

Playwright CLI
CLI for common Playwright actions
Playwright CLI is the official command-line interface for Playwright, a powerful cross-browser automation and end-to-end testing framework that lets developers write and run tests reliably across Chromium, WebKit, and Firefox. The CLI provides an easy entry point for creating new test projects, running test suites, generating test traces, and debugging issues directly from the terminal. Developers can scaffold test files, record browser interactions as code, and run tests in headless or headed modes without needing a complex setup, dramatically reducing the barrier to writing robust UI tests. Playwright-CLI includes utilities for running tests in parallel across multiple devices, capturing screenshots and videos on failures, and outputting detailed reports that help diagnose flaky behavior or regressions. It also integrates with CI/CD pipelines, making it simple to automate testing as part of build and deployment workflows. -

Pokétwo ∆ Autocatcher
The most legit & advanced Poketwo autocatcher
Pokétwo Autocatcher is an automation-oriented tool built around the Pokétwo Discord game ecosystem. It is presented as a lightweight program for catching Pokémon, leveling, market actions, mass trading, spawn tracking, and related Pokétwo workflows. The project emphasizes one-click setup, configuration commands, custom filters, adjustable delays, notifications, and support for both desktop and mobile usage. It also includes systems for rare spawn alerts, catch logging, level queues, market sniping, and market flipping. Because it automates activity in a Discord-based game and references selfbot-style usage, it should be treated as a terms-of-service-risk tool rather than a normal bot framework. It is best described as a specialized game automation project for users who understand the platform and account risks involved. -

Polymer
A Web Component library
Polymer is a lightweight Web Components library that lets you create encapsulated Web Components that work just like standard HTML elements. These elements can be used in building web applications and are reusable. Polymer can be particularly useful when building UI components. Instead of having to constantly rebuild components such as a specific navigation bar or button in different frameworks and for different projects, simply define this component once with Polymer, and you can use it again and again in your future projects. Because Polymer is built on top of the web standards-based Web Components APIs, custom HTML elements made from it are built totally from the platform up and are interoperable across frameworks. Polymer also works across all major browsers. -

Prerender SPA Plugin
Prerenders static HTML in a single-page application
Flexible, framework-agnostic static site generation for sites and SPAs built with webpack. This is the stable 3.x version of prerender-spa-plugin based on puppeteer. If you're looking for the (now-deprecated) 2.x version, based on PhantomJS, take a look at the v2 branch. The goal of this plugin is to provide a simple prerendering solution that is easily extensible and usable for any site or single-page-app built with webpack. Plugins for other task runners and build systems are planned. Framework-specific examples can be found in the examples/ directory. Most usages of prerender-spa-plugin v2.x should be compatible with v3.x. The exception being advanced configuration options that controlled PhantomJS. These have been replaced by pluggable renderers with their own specific configuration options. -

Public Sans
A strong, neutral, principles-driven, open source typeface for text
A strong, neutral typeface for interfaces, text, and headings. Public Sans is a fork of the SIL Open Licensed face Libre Franklin. Public Sans has many similarities with its parent, but differs enough in its particulars that its effect is distinct. Adjusted vertical metrics. Public Sans is about 2% shorter than Libre Franklin, and has slightly looser default line spacing. Tailed lowercase l. The lowercase l character has a hooked tail for disambiguation. (There is also an optional untailed l.) Regularized stroke weight. Public Sans provides a more regular letterform from the conventional Franklin shape for a cleaner, more consistent letterform, especially at small sizes. Non-rounded vertices. Conventional angled vertices result in a sharper, stronger form. Narrower characters. Public Sans is narrower, especially in rounded characters like lowercase e to help with reading flow, especially in longer texts. Looser letterspacing. Public Sans has relatively loose letterspacing for reading. -

Pwnagotchi
Deep Reinforcement learning instrumenting bettercap for WiFi pwning
Pwnagotchi is an A2C-based “AI” powered by bettercap and running on a Raspberry Pi Zero W that learns from its surrounding WiFi environment in order to maximize the crackable WPA key material it captures (either through passive sniffing or by performing deauthentication and association attacks). This material is collected on disk as PCAP files containing any form of handshake supported by hashcat, including full and half WPA handshakes as well as PMKIDs. Instead of merely playing Super Mario or Atari games like most reinforcement learning based “AI” (yawn), Pwnagotchi tunes its own parameters over time to get better at pwning WiFi things in the real world environments you expose it to. To give hackers an excuse to learn about reinforcement learning and WiFi networking, and have a reason to get out for more walks. -
