Deployment
A collection of files that were uploaded to Vercel.
Preview Deployments
Preview Deployments are the default type of deployment. They are made available by pushing to the Git Branch of a connected Git Repository, or by using the vercel command from Vercel CLI.
Learn more about Preview Deployments from the Deployments Concept documentation.
Production Deployments
Production Deployments are a promoted type of Deployment, made available by merging into the Production Branch of a connected Git Repository, or by using the vercel --prod command from Vercel CLI.
Learn more about Production Deployments from the Deployments Concept documentation.
Build
Each deployment creates one or more builds. For example, a static site generator is one build and each Serverless Function is its own build.
Build Step
The Build Step is the process, before a deploymment is made publically available, in which a deployment's source files are constructed to be production-ready output.
Read more about the Build Step in the Build Step documentation.
Run Time
Run Time is the process in the deployment lifecycle that the deployment's code is being executed, after successfully being built through during the Build Step.
Custom Domains
A Custom Domain is a domain that has been added to a user or team for use with a project. Custom Domains are automatically updated when the project they are assigned to gains a new Production Deployment.
Source Files
These are the files contained within your project before it is uploaded with Vercel.
Serverless Function
A serverless code execution handler that can be invoked over the web.
Static File
A file that is not executed, but instead served as-is to the program sending the request.
Project
A structured group of deployments, categorized by the deployment name.
Apex Domain
An Apex Domain is a custom domain without an included subdomain. For example, "my-example.com" is an Apex Domain, but "docs.my-example.com" is not.
Apex Domains are sometimes referred to as "naked", "bare", "base", "root", or "zone apex" domains.
TLD
A TLD is a Top-level Domain, a domain at the highest level of the Domain Name System. For example, ".com" and ".co" are Top-level Domains.
