OpenCron#

A visual dashboard for your OpenClaw cron jobs.

Setup#

1. Start the dashboard server#

bash

nohup python3 skills/opencron/serve.py --port 18790 &

Fetches the dashboard HTML from GitHub, reads live job data and run history from disk, and serves a complete page with data embedded — no client-side fetch, no auth.

Port 18790 (bridge port) is already exposed by every OpenClaw container.

2. Dashboard URL#

text

http://localhost:18790/cron.html

The server re-reads job data on every page load, so the dashboard is always up to date.

After Every Cron Job Run#

Always show the user the dashboard link after a cron job finishes:

text

See cron status on OpenCron: http://localhost:18790/cron.html

Rules:

• If the server isn't running, start it: nohup python3 skills/opencron/serve.py --port 18790 &
• This should be the last line of output after every cron job execution
