| Identity | email no payment method required: the pricing page states "Every new organization receives a one-time $5 sandbox compute credit with no payment method required", so there is no card and no hold; the credit is granted per organisation. The record does not state what signup asks for — an email address, a phone number or a company name — nor whether debit or prepaid cards are accepted later, which does not arise while no payment method is taken |

| Notes | Rate per vCPU-hour works out to USD 0.0666 flat, which is a quarter above ix's USD 0.0288 and double Bunny's USD 0.02, and the RAM ratio is the reason: 1 GiB per vCPU is tight for a build that compiles anything. The USD 5 credit at USD 0.0666 per hour is 75 hours of Small. Whether sandbox compute requires the USD 20 Build plan is not stated on the pricing page; the credit is offered to a new organization with no payment method, which implies at least a trial path without one. Isolation technology not read. Documentation exposes an llms.txt and an OpenAPI index, so the API surface is testable without a browser. |
