Fair questions.
Is it actually free?
The $5 credit is free, and nothing is charged until you top up. A 2 vCPU, 4 GB sandbox running nonstop for a month is $4.76, so the credit covers a full month with change left over. Most agents sleep most of the day, which stretches it a lot further. When the credit runs out, the sandbox sleeps until you add more.
Do I need a card?
Yes. Agent37 gives the starter credit once a card is on file. It's prepaid, so you're only charged when you choose to top up.
What is it, in one line?
A cheap cloud computer for your AI agent. You pick the agent, Agent37 runs the box. They're backed by Y Combinator and say they host over 250 startups.
What does it cost after the free credit?
You pay by the minute for what runs: $0.0011 per vCPU hour, $0.00096 per GB of memory per hour, and $0.00012 per GB of disk per hour. An idle 4 GB disk is about $0.36 a month. They also say that if you find a cheaper sandbox, they'll refund the difference.
