deploy vs release vs ship
"Deploy" is the technical operation of moving code to an environment. "Release" is the product decision to make a version available to users. "Ship" is informal and means the whole thing: built it, deployed it, users have it.
deploy
The technical act of moving code from one environment to another — usually to staging or production. CI/CD pipelines deploy. The word is about the infrastructure operation, not the user experience.
"The pipeline deployed the new build to production at 3 PM."
release
Making a version officially available to users or the public. A release has a version number and often includes release notes. You can deploy without releasing (e.g. behind a feature flag).
"We released version 2.4.0 with the new dashboard to all users."
ship
Informal verb meaning to complete a feature and get it in front of users. It combines building, deploying, and releasing into one action. Common in startup and product culture.
"We shipped the new onboarding flow last Thursday. Users are already signing up faster."
