Switch terminal themes live. Run tstyles, arrow through 18 themes previewing each one in your current tab — Enter keeps it, Esc reverts to exactly how it looked before. The palette, the cursor color and the prompt repaint instantly on any terminal that speaks OSC; on Windows Terminal and WezTerm the font, opacity and animated background come with them. All in one command, all non-destructive.

Works on Windows Terminal, macOS Terminal.app, iTerm2, and any terminal that speaks OSC color sequences — and in zsh and bash, not just PowerShell. Runs on PowerShell 7 and Windows PowerShell 5.1. Keep your own prompt (Oh My Posh / Starship) with tstyles <name> -KeepPrompt.

Install-PSResource -Name TerminalStyles
Import-Module TerminalStyles -DisableNameChecking

On macOS and Linux this needs PowerShell first — brew install powershell, or see Requirements. On Windows it is already there.

Add the Import-Module line to your $PROFILE so it loads on every new shell tab — or run tstyles register once and it does that for you, with a confirm prompt first. It writes to the $PROFILE of each PowerShell engine it finds on your PATH — on Windows that is pwsh 7 and Windows PowerShell 5.1; on macOS and Linux, pwsh and pwsh-preview — skips one that isn't installed, and writes once where two of them share one file. The prompt names each file first. Then:

tstyles

Arrow keys preview each style live, Enter keeps it, Esc cancels.

Prefer a one-line installer, or on a shell without PSResourceGet? See the bootstrap installer.
