Deploy Spring Boot on Light Cloud

Spring Boot is the most widely used framework for production Java services. Light Cloud detects it from spring-boot 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.

How to deploy Spring Boot

  1. 01

    Bring the code

    Pick a repository, upload a folder, or ask Claude Code or GitHub Copilot to put it online.

    github.com/acme/app

  2. 02

    Spring Boot, detected

    The files are read and the build is filled in. Every setting can be changed by hand.

  3. 03

    Built into a container

    An image is built and started, listening on the port the app expects.

  4. 04

    Live

    A light-cloud.io URL in minutes, a preview URL for every branch, and logs and metrics beside it.

    main-app-acme.light-cloud.io

Add a database

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

Questions

How do I deploy Spring Boot?
Connect the repository, upload the folder, or ask Claude Code or GitHub Copilot to deploy it. Light Cloud reads the files, builds Spring Boot and returns a live URL in minutes, with a preview URL for every branch.
How much does it cost to host Spring Boot?
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 Spring Boot 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.
