The agent, what does it do?

Posted on Mar 26, 2026
tl;dr: The agent sends to tinyfal the metrics you want it to.

The agent

The install.sh script just sets up agent.sh in "$HOME/.tinyfal". It contains the following:

#!/bin/sh
# Tinyfal Agent
# This script is run every minute by cron.

# TODO: add agent logic here

The rules

The backend (as for now) validates only the following requests:

  • No more than 5 fields in the metrics payload.
  • No nested dicts.

I don’t want my cloud costs to explode. If this thing works I will introduce pay plans. Or something. If you need it contact via:
