Terminal Theme Studio is a free, browser-based terminal color theme generator. Build a 16-color ANSI palette once, preview it live, and export it to 28 formats — including Kitty, WezTerm, Alacritty, Ghostty, Windows Terminal, iTerm2, Konsole, Contour, foot, Rio, Hyper, Tabby, Warp, and shells such as Bash, Zsh, Fish, and Nushell.
The app runs entirely in your browser with no account and no server-side processing. Enable JavaScript to create and export your terminal theme.
