OpenCron
A visual dashboard for your OpenClaw cron jobs.
Setup
1. Start the dashboard server
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
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:
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
