I’ve been working on gotui, a modern fork of the unmaintained termui, rebuilt on top of tcell for TrueColor, mouse support, and proper resize handling. It keeps the simple termui-style API, but adds a bunch of new widgets (charts, gauges, world map, etc.), nicer visuals (collapsed borders, rounded corners), and input components for building real dashboards and tools. Under the hood the renderer’s been reworked for much better performance, and I’d love feedback on what’s missing for you to use it in production.

Could you build this?

Partial Forking and extending a terminal UI library with widgets is accessible, but building and debugging robust terminal emulator primitives and cross-platform resize/event loops has thorny edge cases.

What it would actually take: A full-featured TUI library requires a low-level terminal engine (like tcell) handling ANSI escape sequences, raw terminal mode, window resize signals (SIGWINCH), and TrueColor multiplexing across disparate terminal emulators. Deep knowledge of terminal escape sequences, terminal I/O, and Go concurrent rendering pipelines is necessary.
