Show HN: A native Rust TUI for Claude Code, because Ink got slow

Category: cli-tool

Tags: tui, rust, claude, performance, cli

Score: 6.5/10 (Innovation: 5, Technical: 7, Documentation: 8, Utility: 6)

A native Rust terminal interface that replaces Anthropic's Node.js/React Ink TUI for Claude Code, offering significantly better performance (20-50MB memory vs 200-400MB, <100ms startup vs 2-5 seconds). It's interesting because it maintains full Claude Code functionality while completely rearchitecting the frontend with Ratatui and communicating via JSON envelopes to the official Agent SDK.

Target audience: backend devs, devops
