What it does

Despite the massive rise of AI/LLM coding agents & execution harnesses and cloud VM administration over SSH, terminal UI innovation has largely stagnated since the 1970s. Most CLI tools still rely on blocking single-threaded I/O, [curses]-era APIs, and fragile platform hacks - or rely on the heavy, fragile workaround of layering web stacks like [Node.js], [React], and [ink] onto the console. This introduces unreasonable memory bloat, high latency, broken keyboard shortcuts, and unpredictable instability that breaks down during long-horizon agentic workflows and sub-process orchestration.
