Supabase Memory Refresh

A tiny GitHub Action that pings the health endpoints of multiple projects once a day. Useful for keeping free-tier projects (Supabase, Render, Fly.io, etc.) awake so they aren't paused for inactivity, and as a lightweight daily uptime check.

The endpoint URLs are stored in a GitHub Actions secret — never committed to the repo — so they stay private even if the repository is public.

How it works

• .github/workflows/scheduled-sync-7c21.yml runs on a daily cron (06:00 UTC) and can also be triggered manually from the Actions tab (Run workflow).
• It reads the ENDPOINTS secret, sends a GET to each URL, and prints only the HTTP status (the URL itself is never printed to the logs).
• The job fails if any endpoint returns a non-2xx/3xx status (or is unreachable).

Configure your endpoints (secret)

1. Go to Settings → Secrets and variables → Actions → New repository secret.

2. Name it ENDPOINTS.

3. Paste one endpoint per line, with an optional label after the URL:

   https://your-project-1.example.com/api/health   project-1
   https://your-project-2.example.com/healthz       project-2
   

Lines starting with # and blank lines are ignored. To add/remove projects, just edit the secret value — no code changes needed.

Change the schedule

Edit the cron line in the workflow. Times are UTC. Use https://crontab.guru. Example — twice a day at 06:00 and 18:00 UTC:

schedule:
  - cron: "0 6,18 * * *"

GitHub may delay scheduled runs during peak load, and disables schedules on repos with no activity for 60 days. A manual run or commit re-enables them.

Run it now

Push to GitHub, add the ENDPOINTS secret, open the Actions tab, select Scheduled sync, and click Run workflow to test before the first scheduled run.
