Open Duet

Build a team of AI coworkers and choose where they run.

Open Duet is an open-source workspace for creating named AI agents, giving them jobs and workspaces, and bringing them together to complete tasks. Keep useful context between conversations, run routines, and review actions before they make changes. Use the desktop app, run your own server, or visit the separate hosted service.

Open Duet does not include an AI model or model subscription. You choose the engine and provider account used for your work.

Status: Open Duet is in active development. Desktop releases, self-hosting,

agent computers, and newer team features are still evolving. Review

known limitations before relying on them for important work.

What you can do

• Create agents and teams. Give agents a name, role, engine, workspace,

memory, and approval settings. A lead can delegate work to specialists or coordinate agents in shared rooms. Team leads can use Claude or Codex. See teams and delegated work.

• Keep useful context. Agents can save notes, recall relevant notes and

conversations, and search their history. You can review and edit what they remember. See memory.

• Run work on a schedule. Create routines for scheduled, webhook, or manual

runs. Review each result and answer requests for approval; a routine never approves an action by itself. See routines.

• Choose how much freedom agents have. Use Ask first, Accept edits, Approve

for me (Claude, Codex, and Cursor), or Plan only. Review tool activity and approval decisions in the app.

• Connect tools and apps. Connect services such as GitHub, Gmail, and Google

Calendar through your own Composio key, then grant access to selected Claude or Codex agents. Changes wait for your approval. Add individual tools from the MCP Marketplace. See connected apps.

• See what needs your attention. The Today view gathers approvals,

questions, routine outcomes, engine failures, and due tasks. It can show read-only Gmail and calendar items. See everyday features.

• Plan and follow work. Use a task board and calendar to assign work,

schedule one-time runs, and review conversations and attempts. See tasks and calendar.

• Reuse instructions. Save skills and start agents from templates. Skills

are instructions you choose for a message. See skills and templates.

• Use it from your phone. Pair the phone app with your own server to chat,

stop an answer, allow or deny a tool call, or create and edit agents and rooms. See the phone app guide.

• Work with files and history. Search conversations, attach text and

images, import audio for transcription with your consent and credentials, browse or download workspace files, and export your history.

Ways to run Open Duet

| | Desktop app | Self-hosted server | Hosted web app | Development checkout | |---|---|---|---|---| | Best for | A personal workspace on your computer | Keeping your agents and routines available on a server you control | Using the separately operated Suparagent service | Contributing or changing Open Duet | | Where workspace data lives | Your computer | Your server | An account-specific hosted workspace | Your development machine or configured database | | Start here | Quick start | Self-hosting guide | suparagent.ai | Development setup | | Main requirements | Node.js 22+, uv, and an engine | Linux server, HTTPS, Docker or Node.js and uv, and an engine | An account and an AI provider account | Node.js, uv, and Docker if you use PostgreSQL | | Status | Experimental | Experimental; single owner | Separate hosted product | — |

The hosted service is separate from the open-source desktop and self-hosted core. Hosted account, workspace, and billing data are handled by Suparagent; see the hosted service's Privacy Policy and Terms.

Hosted plans

The hosted preview lets you use your own Boat key for sandbox compute. Paid plans use compute operated by Suparagent, so you do not need to supply a Boat key. In both cases, you bring your AI provider account and pay that provider for model usage.

| Plan | Monthly Suparagent price | Included running compute | Machine disk capacity | |---|---:|---:|---:| | Free preview | $0 | Billed to your Boat account | Small profile | | Starter | $15 | 100 hours per billing period | 51 GB | | Standard | $49 | 300 hours per billing period | 51 GB | | Pro | $99 | 720 hours per billing period | 111 GB |

Paid-plan compute hours count while the sandbox is running, including idle time. At the limit, it stops until the next billing period or a plan change; compute overages are not charged. The disk value is the selected machine's capacity, not a separate storage quota. A stopped sandbox's disk is subject to the provider's retention period, so export important files before a paid plan ends. Paid checkout is enabled for hosted accounts; see the Suparagent pricing page for current plans.

Engines, data, and costs

Connect an engine you already use: Claude Code or Codex CLI, Gemini CLI, Google Gemini through Antigravity, Cursor, another command-line agent using the Agent Client Protocol (ACP), OpenRouter, or an OpenAI-compatible API such as Ollama or LM Studio. Available tools vary by engine; image input and agent computers, for example, are not supported by every engine. See engine setup and capabilities.

For desktop and self-hosted use, conversations, agent notes, routines, and settings are stored in that instance's local data folder or server database. Workspace files stay in the folders you assign to agents. API keys saved through Open Duet are encrypted there; command-line sign-ins remain with the engine installed on that machine.

When an agent answers, the selected engine receives the prompt and the context needed for that turn. This can include text you attach, relevant notes, and workspace content the engine reads. If the engine is a hosted service, that information is handled under that provider's terms. You bring the provider account, CLI sign-in, or API key; model usage may cost money.

Quick start

The desktop app runs from a source checkout. It needs Node.js 22 or newer, uv, and at least one engine available on the same computer. For a CLI engine, install it and sign in before opening Open Duet. You can also configure an API-based engine in Settings → Engines. Docker is only needed for the optional isolated agent computers.

git clone https://github.com/Anil-matcha/open-duet.git
cd open-duet/desktop
npm run app

On first launch, choose an engine, workspace, and approval mode. Then:

1. Open Settings → Engines and confirm an engine is ready. 2. Create an agent with a name, a clear job, and a workspace. 3. Start a chat. Choose Ask first to pause for approval before actions that need it. 4. Add teammates or create a routine when you want to split up or repeat work.

See the Releases page for current desktop installers and the changelog for changes. Installers are experimental and unsigned. The assisted update flow offers a SHA-256-verified installer for you to open; it does not install updates automatically. The release-to-release update path has not been verified end to end.

Example: prepare a weekly project briefing

Create a lead agent and specialists, such as a researcher and an editor. Give them the same project workspace, and set the lead's engine to Claude or Codex. Ask the lead to prepare a briefing from the notes and reports in that folder.

The lead can split the request into smaller tasks and hand them to the specialists. Their work runs in separate conversations, then returns to the lead to assemble. Follow along in chat and approve actions when the settings require it. Once the process works well, make it a weekly routine and review each run in the app.

Scheduling tasks

Routines run prompts on local agents on a schedule, by webhook, or on demand. They run in the backend, so the backend must stay running. The original Telegram bot and Boat sandbox task flow are optional and separate from the agent workspace. See backend scheduling details and environment settings.

Known limitations

• Open Duet is early and changing. The self-hosted server is experimental and

intended for one owner with paired devices, not a multi-user organization.

• Team delegation is new; lead agents need to use Claude or Codex.
• The phone app has been tried on an Android emulator and an Android phone, not

on iOS. It has no push notifications or store release.

• Docker computers, browser tools, and the macOS native desktop preview are

experimental and opt-in.

• Desktop installers are unsigned and have limited platform verification. See

desktop setup details.

• Connected apps are reached through Composio and tested against a fake

Composio service, not yet the real service. Only Claude and Codex agents can use them, and changes wait for your approval.

• The MCP Marketplace, hosted cloud computers, quiet routine results, and

audio transcription have not had live-service or packaged-app qualification.
