Deploy Quarkus on Light Cloud

Quarkus is a cloud-native Java framework with fast start-up. Light Cloud detects it from quarkus in pom.xml or the Gradle build. It runs as a container that scales with traffic and down to zero when idle.

Free plan, no card. Google or GitHub sign-in.

Managed PostgreSQL in the same project, its connection string one copy away.

Questions

How do I deploy Quarkus?
Connect the repository, upload the folder, or ask Claude Code or GitHub Copilot to deploy it. Light Cloud reads the files, builds Quarkus and returns a live URL in minutes, with a preview URL for every branch.
How much does it cost to host Quarkus?
The Free plan runs up to 3 server apps with $1 of usage a month and no card. A container is billed by the hour only while it runs, so an idle app costs nothing and a quiet one uses about $0.10 a month. Paid plans start at $5 a month with $5 of usage included.
Can a Quarkus app use a database?
Yes. Create a PostgreSQL database in the same project and set its connection string as DATABASE_URL. Databases come with paid plans, from $5 a month.
Can I use my own Dockerfile instead?
Yes. A Dockerfile at the root of the repository always wins over detection: it is built as is and runs as a container.
