description	Daytona cloud server and Den sandbox setup. Use when the user says Daytona server, cloud server, Den server, marketplace server, worker proxy, cloud auth, org policies, or connect Electron to a Daytona server.

Daytona Cloud Server

Use this skill when the user needs the hosted/server side of OpenWork running in Daytona. This is separate from the Electron desktop sandbox.

What This Covers

• Den Web on port 3005.
• Den API on port 8788.
• Worker proxy on port 8789.
• MySQL inside the server sandbox.
• Public Daytona preview URLs for Electron to consume.
• Marketplace, org policy, cloud auth, and server-managed extension flows.

Start Server Sandbox

From the repo root:

bash .devcontainer/test-server-on-daytona.sh [branch-or-commit]

The helper creates a separate server sandbox, starts MySQL, Den API, Den Web, and worker proxy, waits for health checks, then prints URLs.

If dependencies or the base image changed, refresh the server snapshot:

bash .devcontainer/create-daytona-openwork-server-snapshot.sh

Connect Electron To Server

For end-to-end desktop validation, use the daytona-electron-den skill. This section only covers wiring the Electron sandbox to the printed server URLs.

Start a second Daytona sandbox for Electron and point it at the server URLs:

bash .devcontainer/test-on-daytona.sh [branch-or-commit] \
  --den-base-url <DEN_WEB_URL> \
  --den-api-base-url <DEN_API_URL>

For flows that must require cloud sign-in, add --require-signin.

Validate Server Health

Use the public URLs printed by the helper:

curl -sf <DEN_WEB_URL>/api/den/health
curl -sf <DEN_API_URL>/health

Inspect logs if health checks fail:

daytona exec "$SERVER_SANDBOX" -- 'tail -120 /tmp/den-api.log'
daytona exec "$SERVER_SANDBOX" -- 'tail -120 /tmp/den-web.log'
daytona exec "$SERVER_SANDBOX" -- 'tail -120 /tmp/den-worker-proxy.log'
daytona exec "$SERVER_SANDBOX" -- 'tail -120 /tmp/den-db-push.log'

When To Use Two Sandboxes

Use two sandboxes when testing cloud behavior end-to-end: server sandbox for Den and a separate Electron sandbox for the desktop client. This matches production better than trying to run everything inside one desktop sandbox.

Use this for marketplace install/remove/search/filter, org-managed extensions, desktop handoff auth, cloud restrictions, and worker proxy flows.

Evidence

Pair this with the daytona-recording-artifacts skill. Server proof should include health-check output, relevant logs, CDP assertions from Electron, and a recording or screenshot artifact for human review.

Use daytona-flow-validator for pass/fail. Server health alone does not prove Electron cloud behavior works.
