Questions
Plain answers.
- Do I need a card to start?
- No. The free tier starts without one, and it has a hard stop: requests past the allowance are refused rather than billed.
- What happens to a project I stop using?
- Compute drops to zero when nothing runs, so an idle project costs nothing. Stored data and keys stay until you delete them.
