The short answer
Superset is one workspace for Claude Code, Codex and any other coding agent, the pick for a mixed toolchain. Conductor runs several Claude Code agents side by side, each in its own workspace, the pick for parallel work on one repo. T3 Code is the open source control plane. Ship Studio plugs the agent, the repo and the hosting into one window. Berd is the playful desktop app for building with agents.
A terminal tab per agent stops working at three agents. The board has five desktop apps that give coding agents a desk, and they differ on one question each.
Which one runs agents in parallel?
Conductor. It runs several Claude Code agents side by side, each in its own workspace, so three branches move at once and the diffs stay apart. Superset covers parallel work too, and its difference is the mix: Claude Code, Codex and any other coding agent in one workspace, which matters when the team runs more than one vendor.
Which one is open source?
T3 Code. It is an open source control plane for coding agents, and it is the pick for a team that wants to read the code it hands its codebase to. Berd is open source as well, and it is the odd one on the shelf: a weird, playful desktop app for building with AI agents, where less chatting and more building is the whole position.
Which one gets to production?
Ship Studio. It plugs the agent, the repo and the hosting into one window, so the loop from prompt to deployed preview stays inside one app. For a solo maker shipping a side project, that loop is the product.
Which one for a designer?
Berd, then Ship Studio. Berd was built inside itself and it shows, the interface reads as a tool made by people who care what a tool looks like. Ship Studio reads as the deploy button a designer wanted.
The honest caveat
All five are young and all five move weekly. Pick the one whose difference matches the problem today, and expect to look again in a quarter. The wider agent shelf is AI on the board, the browser that lends an agent your session is in AI tools that earn a second week, and the components for the interfaces they produce are in UI components for AI interfaces.
One workspace for Claude Code, Codex and any other agent
The mixed toolchain desk. When the team runs two vendors, this is the one that keeps them in one window.
Pros
- Vendor agnostic
- Parallel work
- Free tier
Cons
- Young, features move weekly
- Team features are paid
Several Claude Code agents side by side, each in its own workspace
The parallel desk for one repo. Three branches at once, diffs kept apart.
Pros
- Isolation per agent
- Built for Claude Code
- Free tier
Cons
- Claude Code first, other agents second
The open source control plane
For the team that reads the code it hands its codebase to. Free.
Pros
- Free and open source
- Speaks to more than one agent
- Readable
Cons
- Less polish than the paid desks
- You maintain the setup
Agent, repo and hosting in one window
The prompt to preview loop for a solo maker. The deploy button a designer wanted.
Pros
- Hosting plugged in
- One window
- Free tier
Cons
- Hosting choice is theirs to support
- Parallel agents are secondary
The playful open source desktop app, built inside itself
Less chatting, more building. The interface reads as made by people who care what a tool looks like.
Pros
- Free and open source
- A point of view
- Built in itself
Cons
- Weird on purpose, which is a taste
- Small team
Questions
Do I still need the terminal?
Yes, for the first run and for anything the desk lacks a button for. Each of these apps wraps the agent's own CLI, so the terminal remains the fallback and the place to read logs. The desk earns its place on the second and third agent, when tabs stop scaling.
Which one is free?
T3 Code and Berd are free and open source. Superset, Conductor and Ship Studio are freemium, with the free tier covering a single workspace or a limited number of agents and the paid tier opening parallel runs and team features. The agents themselves bill separately through their own vendors.
Can I run Codex and Claude Code in the same desk?
Superset is built for exactly that, one workspace for Claude Code, Codex and any other coding agent. Conductor is Claude Code first. T3 Code sits between them as a control plane that speaks to more than one agent, and it is the one to read the code of before deciding.
