Persistent ConPTY session manager for Windows AI coding agents
Experience persistent ConPTY sessions that keep AI coding agents running after a terminal closes or an editor reboots. MUXFleet, from MUXFleet, provides a centralized fleet interface and keyboard-driven monitoring for multiple agent CLIs. It offers real-time Windows toast notifications, lossless session reattachment from any shell, and git worktree integration for isolated agent branches. The target audience is developers running agentic CLIs who need uninterrupted, long-running agent processes on desktop Windows machines.What the tool does for AI agent workflows
MUXFleet runs CLI-based agents in persistent ConPTY sessions, so an agent process continues after you close the terminal window because a background daemon owns the session. The app is designed for command-line agent runtimes such as Claude Code, Codex, and Gemini. It assigns each agent to a managed session ID and lets you reattach with a single command, preserving the agent's live stdout and stdin streams.
How it interacts with system resources and process management
Native Windows process controls keep agents isolated from the interactive shell. The tool uses Job Objects for process management so agents survive editor restarts, and ConPTY for terminal emulation. Real-time status is delivered through Windows toasts and optional audio cues. These choices localize process ownership to the daemon instead of the user shell, which prevents session termination when a terminal window closes.
Safety, workspace isolation, and version control handling
Workspace isolation ties each agent to a separate git worktree, avoiding branch conflicts when multiple agents operate on the same project. The app supports lossless reattachment, which preserves session state rather than attempting risky in-place recovery. It requires CLI-compatible agents and operates within desktop Windows security boundaries, so standard permission models apply.
Interface and operational requirements for different users
The workflow favors keyboard-driven monitoring and command-line control, offering a fleet view optimized for quick switching and scripted attachments. Casual users may find the command set terse, while developers comfortable with shells get immediate access to multi-agent management. The tool targets desktop Windows environments and assumes agent CLIs are already installed and operated from a shell.
Clear specialist tool for developers who run long-lived agentic CLIs
MUXFleet suits developers who need persistent, centrally managed agent sessions and branch-isolated workspaces; it enforces a command-line, Windows-native workflow rather than a graphical, cross-platform one. The main trade-off is platform scope: it targets desktop Windows environments only, so teams that use other desktop platforms cannot employ this tool without a Windows host.
