Sculptor, from Imbue, is a desktop app for running coding agents in parallel, and its README calls it an experimental research preview. If you want something similar that also runs on Windows, with a task board and line-by-line review, Friday is a free, MIT-licensed desktop app. Facts about Sculptor are from Imbue’s own pages and its GitHub README, read on 4 November 2026.
Why would you look for a Sculptor alternative?
Your work shouldn’t own your day, and you shouldn’t have to wait for your platform to be supported. Sculptor’s launch post says Mac (Intel) and Windows support is on the way, and its README lists downloads for Apple Silicon Mac and Linux. If you are on Windows or an Intel Mac, that is the most common reason to look elsewhere.
The other reason is its stage. Its README says it is under active development and should be treated as an experimental research preview, so expect change. That is an honest description, not a criticism, and a research preview can be a good thing to try.
How does Friday compare with Sculptor?
| Friday | Sculptor (from Imbue’s pages and its README) | |
|---|---|---|
| What it is | A free desktop app that runs your coding agents side by side on your own computer | A desktop app for running coding agents in parallel; an experimental research preview |
| Isolation | Each agent can work in its own git worktree | Its launch post says every agent runs in its own container; its docs also describe worktrees and an experimental container backend |
| Agents | Claude Code, Codex, Cursor and 13 more by name, plus any ACP agent | Claude Code, the Pi agentic harness and Codex (with an OpenAI API key), and any terminal-based agent |
| Agents working together | Agents message each other, and when one hits its usage limit the task moves to another with a record of what the first did and changed | We did not find this in its README |
| Planning | A task board that agents take tasks from | Saved session history with plans, chats, tool calls and diffs; the README describes no board |
| Platforms | macOS, Windows and Linux | Apple Silicon Mac, Linux and Linux ARM64; Intel Mac and Windows are described as on the way |
| Licence and price | MIT; free, no account; anonymous usage counts you can turn off | MIT; we did not find a price on the pages we read. Its README says it does not have bandwidth for large outside contributions |

Check its GitHub page for what has changed since 4 November 2026. At that date its latest release was v0.49.0, from 21 October, and its repository had a few hundred stars.
Where is Sculptor stronger?
Its launch post argues that a container for each agent keeps agents out of your local environment, and says worktrees share it. That is a real difference: with a container an agent does not need your machine’s dependencies installed the same way.
Its README also describes a Pairing Mode that syncs an agent’s container changes into your local repository both ways, a merge flow that flags conflicts and can hand them back to the agent, suggestions in beta, and a saved history of each session. If those are what you need, they are worth checking Friday for before you switch.
When is Friday the better pick?
If you are on Windows or an Intel Mac, want a free MIT app with no account, want many coding tools in one place, or want agents to message each other and hand a task on when one hits its usage limit. Friday runs on your own computer, and its agents stop if it sleeps.

What is Friday?
Friday is a free, open-source (MIT) harness for coding agents that work as a team. It runs on your own computer with no account: the desktop app for macOS, Windows and Linux, or one command with Node.js 22 and Git.
- Claude Code, Codex, Cursor and 13 more coding tools (16 by name, plus any ACP agent) run side by side on their own plans and sign-ins.
- One agent splits a job into a task board, the others pick up tasks, and every finished task is checked before it counts as done.
- Agents message each other as they work, and each can work in its own copy of the repository.
- When a tool runs out of usage mid-task, the task moves to the agent best placed to finish it.
- Review each run’s changes line by line, with git built in.
- No account; anonymous usage counts you can turn off; it listens on 127.0.0.1 only.
