Project mention: A list of SaaS, PaaS and IaaS offerings that have free tiers of interest to devops and infradev | dev.to | 2024-02-05Pencil - Open source design tool using Electron.
Mockoon - Used as a logging server instead of using print in the console.
Use Squib so you can separate design and content. You don't want to get halfway through making your cards when you decide to change things about your layout and then have to make the exact same change to a bunch of cards.
Project mention: Phonk - JavaScript scripting for Android devices | news.ycombinator.com | 2024-03-28
Project mention: Show HN: Lua Carousel, create little programs on desktop or mobile devices | news.ycombinator.com | 2023-11-24Well, there is Cardstock, which is a Hypercard-like in progress written in Python (and which uses Python as its language rather than a Hypertalk-like). It seems a bit more modern in that it isn't going for the 1980s Mac aesthetic.
ILua (https://github.com/guysv/ilua). “ILua is a feature-packed, portable console and Jupyter kernel for the Lua language.”
