metaspartan/gotui: Golang terminal dashboard library, advanced modern fork of termui, GOTUI?

gotui is a cross-platform and fully-customizable terminal dashboard and widget library built on top of tcell. It is a modern fork of termui, inspired by ratatui and written purely in Go by Carsen Klock.

This is a modern fork of termui for 2025, heavily upgraded to support TrueColor, modern terminal events, better performance, and new layouts.

gotui is compatible with Go 1.24+.

• Backend: Native tcell support for TrueColor (24-bit RGB), mouse events, and resize handling.
• Gauges: Progress bars and gauges.
• Charts:
  • BarChart: Stacked and standard bar charts.
  • PieChart: Pie and Donut charts.
  • RadarChart: Spider/Radar charts.
  • TreeMap: Hierarchical data visualization.
  • FunnelChart: Process flow/conversion charts.
  • Sparkline: Mini sparklines.
  • Plot: Line, Scatter, and Braille-mode charts.
• Maps:
  • World Map: High-resolution world map example using the generic Canvas widget (see _examples/canvas.go).
• New Widgets:
  • LineGauge: Thin, character-based progress bar with alignment options (Block, Dots, custom runic styles).
  • Scrollbar: Ratatui-compatible scrollbars (Vertical/Horizontal) with mouse and keyboard support.
  • Logo: Pixel-perfect block-style logo renderer.
• Performance:
  • Optimized Rendering: Buffer uses flat slices for O(1) access, providing 2-3x speedup.
  • Zero Allocations: Drawing loops minimized for high-fps scenes (~3000 FPS potential).
• Layout:
  • Grid: Responsive grid layout.
  • Tabs: Tabbed navigation.
  • Interactive: Calendar, Tables, Input, TextArea.
• Styling:
  • Rounded Borders: Optional rounded corners for blocks.
  • Full RGB Color support.
  • Border titles (Top and Bottom) with alignment (Left, Center, Right).
  • Rich styling parser for text.
  • Collapsed Borders: Support for merging adjacent block borders using BorderCollapse.
• Compatibility: Works with modern terminals (iTerm2, Kitty, Alacritty, Ghostty).

It is not necessary to go get gotui, since Go will automatically manage any imported dependencies for you.

go get github.com/metaspartan/gotui/v4

package main

import (
	"log"

	ui "github.com/metaspartan/gotui/v4"
	"github.com/metaspartan/gotui/v4/widgets"
)

func main() {
	if err := ui.Init(); err != nil What do you think?
	defer ui.Close()

	p := widgets.NewParagraph()
	p.Text = "Hello World!"
	p.SetRect(0, 0, 25, 5)

	ui.Render(p)

	for e := range ui.PollEvents() 💬
}

Run an example with go run _examples/What do you think?.go or run each example consecutively with make run-examples.
