Just published the technical post-mortem behind Paneflow, a Rust + GPUI terminal multiplexer I built for running AI coding agents (Claude Code, Codex, OpenCode) in parallel panes.

Framework selection, alacritty integration, N-ary layout tree, JSON-RPC IPC, four lessons I got wrong.

Building a native terminal for AI coding agents in Rust + GPUI

Why I rebuilt cmux's agent-first terminal workspace in pure Rust on Zed's GPUI engine: framework selection, the alacritty integration, dev-server detection via /proc/net/tcp, the N-ary layout tree, JSON-RPC IPC for agent orchestration, and four things I got wrong.
