Save costs by deleting unused projects

Starting January 1, 2024, if a project exceeds the free tier limits in an account, a minimum billing of $5 per project per month will apply to cover backend provisioning and management. To avoid incurring this minimum charge, we recommend deleting unused projects. Additionally, there are no upfront commitments, and you can cancel anytime.
