The invention is applicable to the technical field of computer software and provides a project release method and system, a control terminal and a memory. The project release method includes: receiving a project release instruction; packaging corresponding projects according to the release instruction to form a project package; transmitting the project package to more than two machines; automatically monitoring whether project packages received by the more than two machines are uniform or not; if yes, performing project release. Whether project package versions are uniform or not is automatically monitored and compared, and project release is performed after uniformity is confirmed, and one-by-one manual comparison is avoided, so that project release efficiency is improved.
