Open source · Data Vault 2.0

Data Hopper — model-driven data warehouses on Apache Hop.

We design and build the Hop plugins we wished existed: visual Data Vault 2.0, Business Vault, dimensional models, lineage, and a presentation engine. We also still ship a lot of Apache Hop itself. If your team needs architectural advice or software written in that stack, that is the work.

Open source we ship

Data Hopper is a family of Apache Hop plugins and related engines, published by i-Bridge bv. They are not Apache Software Foundation releases. Install them from GitHub or from the community marketplace repository.

Engine

Hopper Presentation

Metadata-driven presentations and dashboards: server-side SVG layout, data connectors, a browser canvas editor, and print/PDF-capable output. A community alternative to older reporting stacks such as Pentaho Reporting and Jasper.

Hop transform

Pentaho Reporting

Generate PDF, HTML, Excel, CSV, and RTF from classic .prpt files inside Apache Hop. The reporting engine is LGPL, so this plugin lives outside the ASF release — for teams migrating from PDI who still need those reports.

Public server

Hop Web test server

A public Apache Hop Web demo. Sign in with SSO, open pipelines and EDW models (.hsm, .hdv, .hbv, .hdm), and file issues when something breaks. That is a useful outcome.

Try Apache Hop in the browser

The test server at hop-web.data-hopper.com is a real Hop Web instance, not a marketing mock. Use it to evaluate Hop and the Data Hopper modelers. Feedback can go to apache/hop issues or to data-hopper@ibridge.be.

Open Hop Web

Apache Hop contributions

Matt Casters started Kettle (Pentaho Data Integration) in the early 2000s and co-founded Apache Hop. In 2026 he opened over 200 pull requests on apache/hop — GUI, Hop Web, marketplace, transforms, tests, and docs.

Hop Web

Session isolation, SVG canvases, and the APIs that let EDW modelers run in the browser the same way pipelines and workflows do.

Hop Marketplace

Install community plugins — including Data Hopper EDW — from GitHub or a Maven repository without unpacking zips by hand.

GUI and engines

Database perspective, modeling UX, transforms, and the everyday fixes that keep Hop usable on Linux, macOS, and Windows.

Apache Hop is a trademark of the Apache Software Foundation. Data Hopper is independent and is not an ASF product.

How we help companies

The plugins are the public proof. The paid work is helping teams design and deliver data platforms on that same stack — or writing the missing piece when the stack does not cover a specific need.

Technical and solution architecture

Data integration, Apache Hop and PDI migrations, Data Vault 2.0, Business Vault, dimensional warehousing, catalog, and lineage. Advice that is specific enough to implement.

Hands-on delivery

Models, generated loads, quality gates, and Hop projects that a team can operate. The same patterns used in the retail example and the EDW plugin itself.

Software authoring

Hop plugins, reporting and presentation, marketplace packaging, or other work in these stacks when a company has a gap that configuration alone will not close.
