## What it is
Themer is a theme generator that takes a set of colors and outputs themes for editors, terminals, and many other apps, plus matching desktop wallpapers. It is available as a CLI, a JavaScript/TypeScript API, and a web-based progressive web app at themer.dev.

## Use cases
- generate a consistent color theme across my editor and terminal
- create vscode and iterm themes from one color palette
- generate matching wallpapers for my color scheme
- integrate theme generation into my dotfiles
- create a custom syntax theme for vim and sublime text
- use base16 color schemes to generate app themes

## When to choose
- you want one color palette to drive themes across many editors, terminals, and apps
- you want to automate theme generation in dotfiles via CLI or API
- you want matching wallpapers generated from your theme colors

## When to avoid
- you only need a theme for a single app with its own built-in theme editor
- you need a GUI theme designer with live preview for one specific editor
- you are not comfortable with Node.js tooling for CLI/API use

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, theme, developer-tools, templating
- domain: developer-tools, text-editors
- platform: cli, cross-platform
- tags: color-schemes, editor-themes, terminal-themes, wallpapers, dotfiles, syntax-highlighting, pwa, command-line, nodejs, web
