01 / THE WORKSPACE
Your sessions.
Your project. One place.
For developers working across agent sessions: keep the conversations, context, and coordinated work together in a visual project workspace.
Chat with your agents.
See the whole project.
Work directly with individual agent sessions in chat, then arrange them on a shared canvas. Connect notes, screenshots, and project context to the work that needs them.

02 / ORCHESTRATION ACROSS HARNESSES
The right agents.
Working in the right order.
Start with your project.
Open a project workspace, connect your harnesses, and give a Leader an outcome with the context it needs.
Compose the crew.
Build a task graph with the harnesses, models, and skills suited to each assignment. Follow dependencies as the work progresses.
Review what comes back.
Inspect changed files, reported checks, and open questions. Approve and integrate when you’re ready.
EXPLORE GRAPH PATTERNS
Choose the harness, model, and skills for each assignment. Connect tasks with a plan. See the task graph ↗
FAN OUT / FAN IN
Divide the work. Unite the result.
Independent tasks run side by side, then meet at a shared review.
Select a task to read its assignment. In a scrollable graph, use the arrow keys to pan, or Home and End to move to either edge.
THE LEADER
Holds the outcome, breaks down the work, and coordinates the crew. Each Minion gets a bounded assignment.
03 / OPEN BY DESIGN
Built in the open.
Made for your work.
Run Swarmcrews locally with your own authenticated harnesses. Explore the source, shape the roadmap, and extend the workspace around how you build.
04 / START WITH A PROJECT
Bring your agents.
Build together.
Create your first project workspace.
Connect a harness, open a session, and start building.
BEFORE YOU START
Install Node.js 22+, pnpm, and Git. Sign in to one supported harness on this machine.

What exactly is Swarmcrews?+
Swarmcrews is a visual workspace for working with multiple coding agent sessions. Interact through chat and canvas, organize work by project, and orchestrate harnesses, models, and skills through task graphs.
Which agents can I use?+
Claude Code, OpenAI Codex, OpenCode, and Pi. You need at least one authenticated harness on the machine running Swarmcrews. Each ready harness exposes its own configured model catalog.
Can I combine harnesses and models?+
Yes. An orchestrated task graph can use multiple harnesses, models, and skills across its assignments. Connect the harnesses you want to use, then choose from their configured models.
Do Minions each get a separate worktree?+
Minions work in the Leader’s execution checkout. In isolated mode, the Leader has a separate Git worktree. Parallel assignments need distinct file ownership; declared overlapping write scopes are rejected.
Is it free to use?+
Swarmcrews is open source under the Apache 2.0 license. You bring your own authenticated harness and model-service account; your provider’s usage charges and terms still apply.
Is this ready for production?+
Swarmcrews is early-stage software. Expect rough edges and changing interfaces or data formats. Start with a small project, inspect the work, and use the repository’s getting-started guide to build familiarity.
