🌐 Web App

Browser-based code generation from BPMN models — no Gradle or Maven setup needed. Uses the same bpmn-to-code-core engine as the build plugins, so the output is identical. Three ways to use it:

1. Use the hosted version — visit the web app, upload BPMN, download code
2. Self-host with Docker — run the web app on your own infrastructure
3. Call the REST API — programmatic access from CI/CD, scripts, or HTTP clients

Use the hosted version

The fastest way to try bpmn-to-code. Visit the live web app, upload your BPMN file, pick your language and engine, and download the generated Process API. No installation, no Docker, nothing to set up.

Open Web App

Self-host with Docker

For teams that want the web app on their own infrastructure — no data leaves your environment.

docker pull emaarco/bpmn-to-code-web:latest
docker run -p 8080:8080 emaarco/bpmn-to-code-web:latest

Then open http://localhost:8080.

Docker Hub: emaarco/bpmn-to-code-web

Environment Variables

Variable	Description
ALLOWED_CORS_ORIGINS	Comma-separated list of allowed CORS origins, or * for all
LEGAL_LINKS_ENABLED	Enable imprint/privacy links in the UI (true/false)
IMPRINT_URL	URL for the imprint page
PRIVACY_URL	URL for the privacy policy page

Call the REST API

The web app exposes POST /api/generate for programmatic access — call it from CI/CD pipelines, scripts, or any HTTP client. This is a valid option for projects that don't use Gradle or Maven.

INFO

The REST API works but hasn't seen wide adoption yet. If you run into issues, please open a GitHub issue.
