Conductor vs Roost

Where they differ

• Different bottleneck entirely. Conductor assumes you can already reach your machine and your terminals, and that your problem is that five agents editing one checkout is chaos. Roost assumes you can already run agents fine, and that your problem is that the machine is in another room, or another city, or that you are holding a phone.

• One Mac versus a fleet. Conductor is a native macOS app; its scope is the machine it is installed on. Roost is a coordinator with N workers across macOS and Linux, the coordinator itself also a worker, each enrolled with a one-shot command from roost add-machine --platform … and dialling outbound only. The sidebar groups every live session by machine with per-machine CPU, memory, disk, and network tiles, so “run this on the box with free RAM” is a normal thing to do.

• Owning the agent and the git workflow versus owning neither. Conductor launches the agent, gives it a workspace, watches the run, and drives the diff-review-merge loop. Roost never spawns, supervises, or owns an agent, and it has no concept of a branch, a diff, or a merge. The CLI is an ordinary command in a shell, so anything runs, including Claude Code — but nothing about your git workflow is automated for you.

• No client story off the machine. Conductor, Sculptor, and Vibe Kanban all assume you are sitting in front of the computer. Roost’s client is a browser, so the same full application runs on a phone — touch selection, a latching-Ctrl key row, a swipeable deck of terminal cards, a soft keyboard that offsets content instead of reflowing the terminal — and on a tablet with the desktop layout, panes, and shortcuts intact. It installs as a PWA.

• Structured review versus the raw terminal. Conductor’s surface is a diff and a set of checks: a genuinely better way to decide whether an agent’s work is good. Roost’s surface is the authoritative cell grid — rebuilt at one agreed width on resize so history never re-reflows, every frame stamped with a monotonic seq so a reconnecting viewer gets one authoritative full frame, scrollback fetched on demand, and mouse tracking forwarded only when the running program asked for it.

• They compose. Neither tool substitutes for the other’s answer, and using both is coherent: Conductor-style worktree isolation inside a Roost session works, because a Roost session is just a PTY.

What you give up either way

• Choosing Roost costs you: git worktree isolation per agent, diff review, checks, and merge or pull-request flows — Roost offers nothing comparable. Its only code surface is an in-app file viewer reachable by Cmd/Ctrl-clicking an inferred path or #PR link, with #L42 anchors.
• Choosing Conductor costs you: Linux hosts, more than one machine, any client that is not that Mac, a mobile surface of any kind, voice dictation, and any CLI outside the ones it drives.

Use Conductor instead if…

Your bottleneck is git isolation and diff review for parallel agents on one machine, not reaching machines or terminals. If the pain you actually feel is agents stepping on each other’s changes with no good way to read what they did before merging, Conductor is aimed straight at it. Pick Sculptor instead if you want container-level rather than worktree-level isolation.

What Conductor is

Conductor is a macOS app for running parallel coding agents — Claude Code, Codex, and Cursor — each in its own isolated git workspace, so two runs cannot collide. The product is the git workflow around parallel agents: see at a glance what every agent is working on, then review its diff, run checks, merge, and open pull requests. Three others belong in the same category:

• Sculptor (imbue) takes the isolation idea further and gives each agent its own Docker container rather than a worktree.
• Vibe Kanban paired a CLI with a web board over worktree-isolated agents; its sunset was announced after Bloop shut down in April 2026, so it is listed for completeness rather than as a live option.
• emdash is a newer entrant in the same shape.
