Enterprise Edition

Manage links at scale. A set of plug-in modules for organizations that run marketing campaigns, agent-driven automation and compliance exports. It installs as jars on the classpath and changes nothing about the community application.

Modules

Four plug-in modules, each attaching through the community edition's published extension seams.

Module	What it does	Licensed feature
Link meta	Campaigns, tags and placement labels: the `/api/campaigns`, `/api/tags` and `/api/link-meta` endpoints, both admin views, create-form sections, assign-at-create, and the campaign client	`link-meta`
Audit export	Exports the security audit trail through a dedicated endpoint and admin view	`audit-export`
MCP server	Model Context Protocol server so AI agents can drive links, campaigns, tags and statistics — with API-key pass-through, so jCustos stays the single authorization point	—
CLI	Command-line client for scripted and CI-driven link management	—

How licensing works

Plug-in features check their entitlement at runtime against an Ed25519-signed license file. Point the runtime at it with -Dapp.license.file (default license.json).

Without a valid license the licensed features degrade gracefully rather than breaking the application.

Without a valid license

the plug-in endpoint answers 403 license required
its admin views and menu entries do not appear
everything else keeps running exactly as before

Your data is never held hostage

Data written earlier by a licensed feature stays in your store.
It lies dormant while no license is present and becomes visible again as soon as one is.
Nothing is deleted, nothing is held hostage.

Plug-ins, not a fork. Enterprise features install as jars on the classpath, plug into the published SPIs, and degrade gracefully — the endpoint answers 403 license required and its views disappear while the community app runs on. jCustos remains the single authorization point, so no enterprise feature opens a second door into your data.

Deployment

Drop the plug-in jars, plus the license module, onto the host classpath.

# REST server
java -cp urlshortener.jar:plugins/* com.svenruppert.urlshortener.api.ShortenerServer

For the Vaadin UI, add the jars to the war’s runtime classpath. One pitfall worth knowing: as soon as enterprise views contribute dynamic routes, build the frontend with -Dvaadin.optimizeBundle=false, otherwise the production bundle strips the classes those routes need. Community-only builds are unaffected.

Enterprise artifacts are distributed through a private registry and are never published to Maven Central. Both editions carry the same version number.
