Supabase Free Plan Keep-Alive

Prevents Supabase from pausing an inactive project by writing randomised pings to a database table on a recurring schedule.

Overview

The workflow runs every 4 days and performs 25 sequential database writes to the ping table in Supabase. Each write is separated by a random delay between 20 and 60 seconds to simulate organic activity rather than a mechanical burst.

Nodes

Schedule Trigger
Fires every 4 days automatically. A manual trigger is also included for testing.

Code – Generate Items
Creates an array of 25 identical items to drive the loop.

Loop Over Items
Processes one item per iteration until all 25 are complete.

Code – Random Wait
Assigns a random integer between 20 and 60 seconds to each item before the wait step.

Wait
Pauses execution for the duration assigned in the previous step.

Create a Row
Inserts a row into the ping table in Supabase with the current timestamp as created_at.

Setup

1. Create a ping table in your Supabase project with a created_at column (timestamptz).
2. Add your Supabase credentials to the Create a Row node.
3. Activate the workflow to enable the schedule.

Customization

• Change the trigger interval in Schedule Trigger if 4 days does not match your project's inactivity threshold.
• Adjust the item count in the first code node to write more or fewer rows per run.
• Modify the random range (currently 20–60 s) in the second code node to change the spacing between writes.
