How CodeShellManager compares

Last reviewed: October 2026. This space moves fast. If something here is out of date, please open an issue and we'll correct it.

This compares CodeShellManager (CSM) with tools for running several AI coding agents at once on Windows. Competitor details come from each tool's own documentation and from published reviews (linked under Sources), not from hands-on benchmarking. A ? means we couldn't confirm it either way.

Popular tools without a Windows build (Conductor, Superset, cmux) are left out.

The tools

Tool What it is Windows Licence
CodeShellManager WPF terminal host for many real CLI agent sessions, with search, groups and sleep Native MIT
Claude Code Desktop Anthropic's official app: chat-style UI for Claude, with panes, diffs and previews Native Proprietary
Nimbalyst Desktop workspace with Claude Code and Codex sessions on a kanban board, plus editors Native MIT
Orca Sends one prompt to several agents, each in its own git worktree, and compares results Native MIT
Herdr Rust terminal multiplexer that tracks whether each agent is working, blocked or idle Beta Apache-2.0
Claude Squad Go terminal UI on top of tmux and git worktrees WSL only AGPL-3.0
GridVibe Python grid of agent, SSH and WSL panes, with offline voice input Native (needs Python) ?

Where CodeShellManager stands out

  1. It runs the real CLI, so you lose nothing. Chat-style apps wrap the agent in their own UI, and features fall off at the edges. For example, Claude Code Desktop's docs note that plugins aren't available in WSL sessions and that its terminal pane is local-only. CSM runs claude exactly as Windows Terminal would, through your PowerShell 7 profile, so hooks, plugins, the status line and profile functions all work. It's agent-neutral too: Copilot CLI, Codex, Gemini, aider or a plain pwsh run the same way.

  2. Full-text search over everything any session printed. All terminal output is indexed to SQLite FTS5. With many agents running, the question that matters is "which session printed that error, URL or decision?". CSM answers it even for closed sessions, and can relaunch a closed session from the search result.

  3. Built for large fleets. Up to 18 panes on screen, groups with bulk actions, sleep and wake, restart-all, and staggered Claude launches that avoid corrupting Claude's shared config file. CSM is tuned and measured at 50+ sessions, and sleep keeps dozens of projects one click away without dozens of live processes.

  4. A native Windows app. Built on ConPTY, Windows' own pseudo-terminal API, with no Electron, Python, daemon, tmux or WSL prerequisite. Installs from winget or Chocolatey and needs no account.

  5. Run commands that don't touch the agent. F5 runs tests or a build in a separate background process with its output in a drawer, then pastes that output to the agent in one click.

  6. Smaller touches. Programs in a session can push their colour, git branch and title to CSM via OSC 9001, so SSH tools can report state. Each project has a searchable notepad. Ctrl+Shift+T reopens a closed session. Windows Terminal profiles import with their fonts and colour schemes.

Where it lags

  • No "agent is working" state. CSM knows when a session is waiting for you, but not when it's busy. Herdr tracks working, blocked, done and idle for about 25 agents: #154.
  • No diff or review view yet: #148.
  • Closing the window ends the sessions. Close-to-tray with live status is planned: #149.
  • Worktrees are one click, not automatic. CSM creates, lists, jumps between, prunes and removes worktrees from the git menu, but Orca, Claude Code Desktop and Nimbalyst make one worktree per task the default.
  • No mobile or remote companion.
  • Windows-only, by design.
