Three Independent Projects Now Ship Multi-Harness Agent Control Surfaces — AionUi at 31,747 Stars, t3code at 17,477, agent-of-empires at 3,022
A distinct category has formed around one job: watching and steering many concurrent coding agents from a single pane. AionUi (31,747 stars, TypeScript) markets itself as a 24/7 'Cowork' app spanning OpenClaw, Hermes, Claude Code, Codex, OpenCode and 20+ more CLI agents; agent-of-empires (3,022 stars, Rust) offers TUI and web control with explicit mobile access across Claude Code, OpenCode, Mistral Vibe, Codex CLI, Gemini CLI, Pi.dev, Copilot CLI and Factory Droid; t3code covers five harnesses from phone and desktop. None of the three has locked in a dominant abstraction yet, and all three independently converged on harness-agnostic adapters rather than betting on one vendor.
