ohmyzsh
🙃 A delightful community-driven (with 2,500+ contributors) framework for managing your zsh configuration. Includes 300+ optional plugins (rails, git, macOS, hub, docker, homebrew, node, php, python, etc), 140+ themes to spice up your morning, and an auto-update tool that makes it easy to keep up with the latest updates from the community.

Project mention: Show HN: Gova – The declarative GUI framework for Go | news.ycombinator.com | 2026-04-23
The code looks nice, but when I read GUI, I want to see screenshots of GUIs.
Apparently a major dependency is "Fyne", which does show some screenshots on their page:

iTerm2-Color-Schemes
Over 450 terminal color schemes/themes for iTerm/iTerm2. Includes ports to Terminal, Konsole, PuTTY, Xresources, XRDB, Remmina, Termite, XFCE, Tilda, FreeBSD VT, Terminator, Kitty, MobaXterm, LXTerminal, Microsoft's Windows Terminal, Visual Studio, Alacritty, Ghostty, and many more
I made the "Aardvark Blue" a while back[1] to solve some of the problems that most color schemes have. The goal of this theme is that:
- colors are fairly natural
- background and black are distinct
- grays are naturally ordered avoiding full black
- light and dark colors are distinct from each other
- all colors look good on background, black, dark gray, gray, white
We use this for all the screenshots on https://ratatui.rs and https://github.com/ratatui/ratatui
It's available from the usual places https://iterm2colorschemes.com/, https://windowsterminalthemes.dev/?theme=Aardvark%20Blue, built in to ghostty, extension for vscode etc.

Theme choice matters because developers stare at the theme for hours. Dark and light themes can both work well if contrast, saturation, and ambient lighting are handled carefully. I have found Catppuccin pleasant because it is not too loud and can be tuned across tools.

Project mention: Vanilla JavaScript Support for Tailwind Plus – Tailwind CSS | news.ycombinator.com | 2025-07-25
I agree, take a look at Bootswatch: https://bootswatch.com
I find it very nice that you can re-theme or brand your app with virtually no code or class changes.

There's so many plugin systems for zsh. From comments it seems like Pretzo is the main one suggested.
But there's a huge list of different offerings. Looking at https://github.com/sindresorhus/pure?tab=readme-ov-file#inte... , there's also for example zim, zplug, zinit, zi. It's be so great to have see some deeper investigations or comparisons: is Pretzo really the best choice? Aside from seeming popularity, why?
At least found this neat gist with a cheat sheet for different zsh plugin systems (and how very many there are!)
