your ideainto a deployed app.

Build production-ready Spring Boot applications with AI, and deploy them in minutes.

Test safely in your browser with automated testing, live API previews, Swagger, and built-in synthetic data.

A modern, reliable stack built for real backend engineering.

BreezeBuild is deliberately opinionated. Its agents follow a defined engineering philosophy, with tooling, conventions, testing practices, and reliability patterns baked into every project.

Java 21

Language

Modern Java as the foundation. BreezeBuild starts with current JVM capabilities and strong, maintainable backend fundamentals.

Opinionated by design.

BreezeBuild agents do not generate arbitrary code. They work within a rigid engineering philosophy with predefined project structure, coding conventions, testing practices, reliability patterns, and backend principles.

AI accelerates. You stay in control.

Every AI change happens in small, reviewable steps. BreezeBuild explains what changed, why it changed, and how it works, then presents an organized diff for human approval before moving forward.

Built for greenfield backend projects where speed should never require sacrificing engineering discipline.

The backend workflow, in your browser

Your backend. Our defaults. Your control.

You know backend engineering. BreezeBuild removes the repetitive setup and enforces good defaults so you can get to the interesting parts faster.

Guiding agents help you make decisions, implement changes, test, review, and deploy — while you remain in control.

Built for greenfield Spring Boot projects.

You know how to build it.
BreezeBuild helps you build it faster.

BreezeBuild AgentProposed change

I recommend PostgreSQL + Flyway for persistence and Resilience4j for service resilience.

Why this change?Keeps the project consistent with BreezeBuild conventions and avoids unnecessary infrastructure.

Guided

Agents help with the decisions you'd rather not repeat.

Reviewable

Every meaningful AI change is small, explained, tested, and reviewable.

Deployed

Go from a clean Spring Boot project to a real preview without managing the infrastructure yourself.

Build like a Ferrari. Keep your hands on the wheel.

Move fast without giving up engineering discipline. The agent does the heavy lifting; the engineer stays in the driving seat.

Spend your time on the product, not the scaffolding.

Transparent pricing. No surprises.

BreezeBuild keeps the platform simple: one predictable subscription, with AI and infrastructure usage metered separately through Breeze Credits.

BreezeBuild subscription

$20/ month

Your subscription stays $20/month.

The fixed platform fee. It does not move with how much you build.

Breeze Credits

1 Breeze Credit= $1

Metered, not bundled.

Credits map to real variable usage, at cost parity with the dollar. There is no conversion rate to decode.

Vendor, model, and service names are shown whenever they are available. Storage and networking appear as their own lines when they apply.

Your usage is traceable.

Every charge maps to the vendor, model, and service that produced it. BreezeBuild does not hide AI or infrastructure costs behind an opaque token system.

AI that optimizes for efficiency

BreezeBuild's AI agents are designed to minimize unnecessary model calls, compute, and infrastructure usage while helping developers build and iterate quickly.
