This site started as a personal tool. I wanted a better way to understand how my npm packages were doing, not just a single weekly downloads graph, but a precise overview across everything I've authored or maintained.When I couldn't find a good alternative, I built one. The goal is simple: make it easy to see what's happening across your packages without clicking into each one. Downloads, trends, and key signals should be visible at a glance.Over time it grew into a stand-alone site with a dashboard and extra signals like package health. Authentication is handled via GitHub login through Supabase, so you can quickly get a personalized view of the packages you care about.Package health is designed as a practical summary, combining signals like security, maintenance, quality, provenance, and popularity, with guardrails to avoid "everything is fine" scores when security looks risky. It's not meant to replace deep audits, but to help you spot what deserves attention.If you maintain libraries, publish frequently, or just want a better overview of your package portfolio, I hope this becomes the place you check first.

@hybrid-compute is a flexible, modular compute orchestration framework that dispatches computational tasks to the most appropriate backend — whether that's:<ul><li>The local JS thread (for fast, simple tasks)</li><li>A dedicated Web Worker (for multi-threaded offloading)</li><li>Or a remote compute service over HTTP or WebSocket</li></ul>All you do is define tasks and call runTask(). HybridCompute takes care of the rest.

Wrapture lets you go from a Python-trained model to deployable JavaScript with a single command. It generates TypeScript bindings and a Web/Node-compatible wrapper, using WebGPU/WASM-ready ONNX runtimes.NOTE: This is an experiment trying to fulfil a need between python and js. YMMV

Interstellar is a small project I dabble with from time to time between clients. The goal is to ultimately have a 1:1 simulation of our galaxy and to be able to view information and follow all known celestial bodies, including calculating trajectories of asteroids.

This site is the web implementation of <a target="_blank" rel="noopener noreferrer" class="break-all link-break text-gray-500 hover:underline" href="https://github.com/phun-ky/moebius">@phun-ky/moebius</a>: @phun-ky/moebius (Möbius) was created to fit a need I had regarding color palette generation, and as a little challenge to myself. I was never happy with the current online palette generators, and I did not want a "set up" palette, I wanted something that was generated, ready to use, and something that I could use as inspiration on colors to choose from in my projects.

SPECCER is a zero dependency JavaScript package to highlight elements on web pages and in documentation. It's easy to use and highly customizable, making it the perfect tool for developers, designers, and content creators alike.SPECCER was originally created to make it easier to document components in a design system, but you can use it for whatever you like, whenever you need to highlight any element in your web projects.With SPECCER, you can highlight any element on a web page or in documentation with pins, markers, arrows, and more. This can be useful for a variety of purposes, such as:<ul><li>Showcasing the different parts of a component or design system</li><li>Documenting how to use a particular element or feature</li><li>Drawing attention to important information</li><li>Creating interactive tutorials or demos</li></ul>SPECCER is incredibly easy to use. Simply add the data-speccer (or other tags for other features) attribute to any element you want to highlight, and SPECCER will do the rest. You can also customize the look and feel of SPECCER to match your own branding or style guide.
