Keep Supabase free plan projects alive with scheduled database pings

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 createdat. --- Setup 1. Create a ping table in your Supabase project with a createdat 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.
