Add Postgres or Redis to give your app persistent storage and caching. Attach a domain you own or buy one through Locus, with SSL included. Your agent can manage both through the Build API, or you can use the dashboard.

​
Available addons

Each addon costs $0.25/month from workspace credits.

​
How addons work

1

Create an addon

Choose a name and your service’s environment. Wait until the status is available: usually 30–60 seconds for Postgres or 10–20 seconds for Redis.
2

Connect your service

Add an explicit variable reference, such as "DATABASE_URL": "${{db.DATABASE_URL}}". Only services that reference an addon receive its connection variables.
3

Redeploy

Deploy the service again to load the connection values.
See variables and connections for templates and the addon reference for API requests, queries, and migrations.

​
Custom domains

Every service already has a public HTTPS URL. Add a custom domain when you want your own address.

​
Bring your own domain

1

Add the domain

Enter your domain in the dashboard. Locus provides a CNAME target and SSL certificate validation records.
2

Update DNS

Add the supplied records at your DNS provider, then verify the domain in Locus. DNS changes usually take 1–30 minutes.
3

Attach the service

Once DNS and the certificate validate, select the service that should receive the traffic.

​
Purchase a domain

Search for a domain in the dashboard and review its price. Complete the purchase with your contact information, then attach it to a service once registration finishes. Registration usually takes 1–15 minutes; Locus configures DNS and SSL automatically. Use the domain reference to have your agent search, purchase, verify, or attach a domain.
