I open-sourced a tiny n8n workflow that keeps all your free-tier Supabase projects from pausing (reads a Google Sheet, so you can add projects without touching the flow)
Hey folks,
Supabase free-tier projects pause after ~7 days of inactivity. I have a bunch of side projects and client demos running on free tier and I kept losing track of which ones were napping.
So I built SupaPing - a small, open-source n8n workflow:
- Your Supabase projects live in a Google Sheet: name, project_url, anon_key, table, enabled
- n8n runs on a schedule (default: every 6h, totally overkill — 24–48h is fine)
- For each enabled row it does one GET /rest/v1/{table}?select=*&limit=1
- Optional email alert on failure
- Add/pause a project = edit one row in the sheet
What I like about the approach:
- One workflow handles unlimited projects
- Non-technical collaborators can manage the list
- Uses only the anon key + a dedicated empty keepalive table with RLS — no sensitive data exposed
- Works on self-hosted n8n or n8n Cloud
README has the SQL to create the keepalive table and RLS policy, plus import steps.
MIT-licensed. Ideas, issues, PRs all welcome — especially more notification channels (Slack/Discord/Telegram) and non-Google-Sheets sources.

If you've solved this differently (cron + curl, GitHub Actions, edge function, etc.), curious to hear your approach.
