Three kinds of tool, and where Portia sits.
Workspaces and multiplexers (Conductor, Superset, Claude Squad, Vibe Kanban) give each task its own worktree and a place to watch it. The person is the orchestrator: you choose what to start, review each branch and merge each one. They run many agents; they run nothing in a particular order.
Hosted agents (Devin, Codex, Copilot's coding agent, Cursor's cloud agents) take one issue into a sandbox on the vendor's machines and return one PR. Nothing of yours runs; nothing spans issues.
Orchestrators (Bernstein, Portia) decide the order, run gates, and land the work. Bernstein decomposes a goal and merges to main through a queue. Portia takes an epic from your tracker, lands the shared code first, writes the acceptance specs before any feature work, gates every child on its rebased head, and leaves one PR for a person to merge.
Each page below has the same sixteen rows, a section on what the other tool does better, and its sources. Facts were last checked in October 2026; these tools change monthly, so where a price or a plan matters, check the vendor.
- Portia vs Claude Code on its ownthe agent Portia drives
Claude Code already has worktrees and subagents. Portia adds the plan, the tests-first spine, the gates and the single PR for an epic.
- Portia vs ConductorMac app, one workspace per task
Conductor gives each task a workspace with its own worktree, terminal, diff and PR, and lets you run Claude Code, Codex, Cursor and OpenCode side by side. You plan, review and merge each one.
- Portia vs Supersetdesktop workspace for any CLI agent
Superset runs any CLI agent in parallel worktrees on machines you own, with diff review, PRs, a browser and remote access. It is a desk to run agents from; the plan and the merge are yours.
- Portia vs Claude Squadterminal multiplexer for agent sessions
Claude Squad keeps several agent sessions apart with a tmux session and a worktree each, behind one TUI. It is the lightest tool in this list, and it does nothing else on purpose.
- Portia vs Vibe Kanbankanban board for coding agents
Vibe Kanban is an open-source board where each card runs an agent in its own worktree and merges back with one click. The company behind it closed in April 2026; the project continues in the community.
- Portia vs Bernsteindeterministic orchestrator
Bernstein is the closest in spirit: a goal decomposed into tasks, a worktree each, lint, type and test gates, and a merge queue. It merges to main itself; Portia leaves that to you, and keeps the plan in your tracker.
- Portia vs GitHub Copilot coding agenthosted, one issue to one PR
Assign an issue to Copilot and it returns a PR from an Actions environment. GitHub's own guidance says it suits low-to-medium complexity tasks in well-tested codebases, one at a time.
- Portia vs Devinhosted AI software engineer
Devin takes tickets from Linear, Jira, GitHub or Slack into a cloud sandbox and returns a PR. MultiDevin fans one task across up to ten workers. It is hosted end to end and billed in compute units.
- Portia vs OpenAI Codexhosted cloud agent, many tasks in parallel
Codex runs each task in its own cloud environment, many at once, and proposes a PR for each. It needs nothing of yours to run; Portia runs on your machine and lands one feature as one PR.
- Portia vs Cursor cloud agentshosted agents from the Cursor editor
Cursor's cloud agents each run in their own VM and come back with a PR, screenshots and video. They start from the editor, the web, Slack, Linear or a phone. Portia is the planned, gated, one-PR counterpart on your own machine.
