agent-tui runs terminal programs on a PTY and exposes the rendered screen as text or an outline with stable refs. Agents can drive live TUIs, including other AI agents, by snapshotting, pressing keys, and waiting for screen state.
Stop Making TUIs
Our field has a weird relationship with terminal and command line interfaces. The time has come to re-evaluate it.
cmux - The terminal built for multitasking
Free and open source macOS terminal for AI coding agents. Works with Claude Code, Codex, OpenCode, Gemini CLI, Kiro, Aider, and any CLI tool.

Recent agentic systems (Claude Code, Codex, RLM, etc.) push context out of the prompt and into the environment (e.g., as files). This helps them maintain long-term knowledge about their goals and functionality.🚨 While this is a good idea, we show a surprising result: systems… pic.twitter.com/XHFVaDcr4l— Joshua Gu (@astrogu_) May 20, 2026

I Hated Every Coding Agent, So I Built My Own — Mario Zechner (Pi)
The Emacsification of Software
We’re all reading a ton of Markdown. It’s been the lingua franca of software development since long before LLMs. But now agents have led us into a cursed renaissance of TUI tooling, and the reading experience has become intolerable. I’m certain that at least 14% of the agita about AI code is driven by exhaustion over incessantly scrolling terminal Markdown.
Generative UI: The AI agent is the front end
In a new model for user interfaces, agents paint the screen with interactive UI components on demand. Let’s take a look.
We built the GUI for AI - agentic workflows now have a canvas
