Terminal UIs are back—AI coding tools like OpenCode embrace terminal interfaces, k9s manages Kubernetes clusters, and btop++ monitors systems—but the development workflow remains stuck in the 1980s. Write code blind, compile, test in terminal, repeat. TUI Studio changes this by bringing Figma-style visual design to terminal applications for the first time, letting developers drag-and-drop components, preview layouts in real-time ANSI, and export to six major frameworks.
This isn’t just another dev tool. It’s a signal that the TUI ecosystem is maturing from hacker tools to professional workflows.
What TUI Studio Actually Is
TUI Studio is the first visual editor specifically for terminal user interfaces. Think Figma, but for applications that run entirely in the terminal like htop, lazygit, or k9s.
The tool provides a drag-and-drop canvas with 21+ built-in components: buttons, text inputs, tables, modals, progress bars, and more. Choose from three layout engines (Absolute, Flexbox, Grid), apply one of eight color themes (Dracula, Nord, Gruvbox), and watch your design render in real-time ANSI preview. Projects save as portable JSON files, making them version-control friendly.
Export support targets six frameworks: Ink (TypeScript), BubbleTea (Go), Blessed (JavaScript), Textual (Python), OpenTUI (TypeScript), and Tview (Go). The tech stack is modern—React 19, TypeScript 5.8, Vite 7—and the license is MIT. Installation takes minutes:
git clone https://github.com/jalonsogo/tui-studio.git
cd tui-studio
npm install
npm run dev

Why Terminal UIs Are Having a Moment
The TUI renaissance isn’t nostalgia—it’s driven by practical necessity. Cloud-native infrastructure scales, edge deployments multiply, and remote-first workflows become standard. Lightweight, secure terminal interfaces are the gateway to servers, databases, CI/CD pipelines, and even AI-assisted development environments.
OpenCode, the standout open-source AI coding tool of 2026 with 95,000+ GitHub stars, runs entirely in the terminal with a polished TUI. Charm recently released Crush, an AI coding agent that works in your terminal—a direct response to developers who “dread using Cursor’s VS Code-centric UI.” Meanwhile, k9s manages Kubernetes, lazygit simplifies Git workflows, and btop++ monitors systems. These aren’t niche tools anymore. They’re mainstream developer infrastructure.
Yet the tooling to BUILD TUIs hasn’t caught up. Until now, developers sketched layouts on paper, wrote positioning code manually, and iterated through painful compile-test cycles. TUI Studio fills a gap that’s existed for decades.
The Code-First Problem TUI Studio Solves
Traditional TUI development requires writing layout code without visual preview. With frameworks like Ratatui, BubbleTea, or Textual, you specify component positions, styles, and layouts in code, then run the application to see results. Adjust a padding value? Recompile and rerun. Misalign a table? Back to the editor.
One developer described the pain: “With low-level TUI libraries like Ncurses, every state change and update to the UI, down to the exact row and column, must be handled manually.” Another titled their blog post “I Made a TUI in C… and regretted it.” Unicode rendering issues compound the frustration—emojis and certain symbols occupy one or two character cells, and terminals disagree on how to render them, breaking table alignment and causing visual artifacts.
TUI Studio collapses minutes-long iteration cycles into seconds. Drag a component, adjust spacing, switch themes, and see the result instantly in ANSI preview. Consequently, this isn’t just faster—it makes TUI development accessible to developers who’d otherwise skip building terminal tools entirely. Prototyping a dashboard layout? Five minutes in TUI Studio beats an hour writing Flexbox logic blind.
How TUI Studio Fits the Ecosystem
TUI Studio doesn’t replace frameworks like Ratatui, BubbleTea, or Textual—it complements them. Use TUI Studio for visual prototyping, layout iteration, and design communication. Use frameworks for business logic, state management, and production code.
The optimal workflow is hybrid: design layouts visually in TUI Studio, export the code skeleton (when the feature launches), then add logic in your framework of choice. This mirrors how frontend developers use Figma to design, then implement in React or Vue.
Framework choice still matters for production apps. Ratatui (Rust) uses 30-40% less memory and has a 15% lower CPU footprint than BubbleTea (Go), making it ideal for high-performance dashboards and log monitors. BubbleTea’s Elm-style architecture provides cleaner patterns for most applications, and version 2 offers 30% faster rendering. Textual (Python) is a full framework with OOP-style lifecycle management and rich widget libraries, perfect for Python-first teams.
TUI Studio abstracts these differences during design. Choose your framework later based on performance needs and language preference.
What This Means for TUI Development
TUI Studio signals a maturation point for the terminal UI ecosystem. For decades, TUI development has been the domain of systems programmers and CLI hackers willing to wrangle Ncurses. Visual design tools lower the barrier to entry, making TUI development accessible to the same developers building web UIs.
This matters because terminal interfaces are becoming mission-critical infrastructure. AI tools, cloud management, DevOps workflows—these increasingly live in the terminal. As adoption grows, tooling must professionalize. Moreover, TUI Studio is the first step. Expect design systems for terminals, component libraries, and collaborative design workflows to follow.
One telling detail: TUI Studio’s creator noted that “most code was written by Claude.” AI-assisted development is making TUI tooling easier to build, which accelerates ecosystem growth. The feedback loop is reinforcing: better tools drive adoption, which drives better tools.
If you’re building CLI tools, internal dashboards, or DevOps utilities, TUI Studio is worth exploring. Even in alpha, it solves a real problem: prototyping terminal layouts without writing code blind. When export functionality lands, it’ll become essential.
