Frequently asked questions
How do I make colored terminal output with ANSI codes?
Use the Builder to pick foreground and background colors (named, 256-color or truecolor) and styles like bold, dim, italic, underline, blink and strikethrough, then copy the escape code, shell command or Python snippet.
How do I decode an existing ANSI escape sequence?
Paste it into the Decompose tab to split it into its component parts.
Can I preview the result?
Yes, a terminal-style preview shows your styled text live.
