The agent fleet manager is now its own product category.

Three repos in this week's data exist purely to run many coding agents at once: superset-sh/superset at 12,526 stars ("run an army of Claude Code, Codex etc."), agent-of-empires at 2,854 stars with both a TUI and a mobile-accessible web UI, and ruvnet/ruflo at 65,384 stars as an "agent meta-harness" for multi-player swarms. None of them write code. They supervise the things that do. agent-of-empires supports seven harnesses (Claude Code, OpenCode, Mistral Vibe, Codex CLI, Gemini CLI, Pi.dev, Copilot CLI, Factory Droid), which tells you fleet managers are being built provider-agnostic by default now. A supervision layer with its own UX conventions (fleet view, mobile check-in, per-agent status) is what it looks like when the bottleneck moves from generation quality to orchestration and attention management. The mobile access detail is the one I find most telling: the emerging use case is supervising long-running agent work while away from the desk.
