Deploying applications on Unkey is in public beta. To try it, select
Projects in the dashboard sidebar and create a project. Deployed
resources are free until August 1, 2026. We’re eager for feedback, so let us
know what you think on Discord,

*.unkey.app subdomains with no DNS configuration required. These domains are available as soon as the deployment completes.
Immutable vs sticky
Wildcard domains fall into two categories based on how they resolve over time. Immutable domains are locked to a specific commit or deployment and never change. The same URL always returns the same version of your app. Use immutable domains when you need a permanent reference to an exact version, for example in incident reports, audit trails, or rollback verification. Sticky domains follow the latest deployment that matches a condition (a branch, an environment, or production). The URL stays the same, but the deployment behind it changes as you push new code. Use sticky domains for bookmarks, CI/CD integrations, and sharing preview links that stay up to date.Immutable domains
{project}-{app}-git-{sha}-{workspace}.unkey.app
Tied to a specific commit. Once created, it always resolves to the deployment built from that commit.Example:
myapp-api-git-a1b2c3d-acme.unkey.appDeployments created via CLI upload include a random suffix to prevent collisions when deploying from a dirty git state.{project}-{app}-dep-{id}-{workspace}.unkey.app
Tied to a specific deployment ID. Similar to commit domains, but references the deployment rather than the commit.Example:
myapp-api-dep-xyz789-acme.unkey.appSticky domains
{project}-{app}-git-{branch}-{workspace}.unkey.app
Follows the latest deployment on a given branch. Each time you push to the branch, this domain updates to point to the new deployment.Example:
myapp-api-git-main-acme.unkey.appBranch names are slugified: non-alphanumeric characters become hyphens, and the name is truncated to 80 characters.{project}-{app}-{environment}-{workspace}.unkey.app
Follows the latest deployment promoted to a specific environment. When you promote a new deployment or roll back, this domain updates automatically.Example:
myapp-api-staging-acme.unkey.app{project}-{app}-{workspace}.unkey.app
A short-form URL that always resolves to the current production deployment. Unkey creates this domain only for the production environment.Example:
myapp-api-acme.unkey.app
