Open-Source Platform That Makes Public Budgets Transparent and Comparable Across Europe

digitalPilotedTRL 7

Imagine every city and government agency publishes their budget online, but each one uses a different format — like trying to compare grocery receipts written in different languages. This project built a free online platform that takes all those messy budget files, converts them into one standard format, and lets anyone visualize, compare, and analyze where public money goes. It was tested in real municipalities in Spain and used by journalists and anti-corruption watchdogs to spot suspicious spending patterns.

The business problem

What needed solving

Public sector budgets and spending data are published in dozens of incompatible formats across thousands of agencies, making it nearly impossible to compare, audit, or analyze spending patterns at scale. Journalists, anti-corruption organizations, and even government auditors waste enormous time manually collecting and reformatting data before any analysis can begin. This opacity enables misallocation and corruption to go undetected.

The solution

What was built

An open-source SaaS platform with four main components: semantic data conversion tools that unify heterogeneous budget formats into a single standard, a visualization library for exploring budgets by time, location, and administrative level, data mining tools for spotting trends and anomalies, and a citizen engagement interface for public feedback. The final integrated platform was deployed in 3 Spanish municipalities and tested across 3 pilot scenarios. The project produced 52 deliverables in total.

Business applications

Who can put this to work

GovTech / Public Administration Software

SME

Target: Companies building e-government or civic tech solutions

If you are a GovTech company struggling to integrate financial data from multiple public agencies that each use different formats — this project developed open-source semantic lifting tools and a standardized data model that converts heterogeneous budget data into one unified format. The platform was deployed in at least 3 municipalities in Spain and designed to serve thousands of public administrations.

Media & Investigative Journalism

any

Target: Data journalism organizations and newsrooms

If you are a news organization investigating public spending but spending weeks manually collecting and cleaning budget data from dozens of sources — this project built data mining and visualization tools specifically designed for budget scrutiny. The platform includes comparative analysis across different administrative levels and was piloted in a data journalism scenario with 9 partner organizations across 7 countries.

Anti-Corruption & Compliance Consulting

mid-size

Target: Compliance firms and NGOs monitoring public procurement

If you are a compliance consultancy helping clients assess corruption risk in public procurement — this project developed statistical analytics and pattern detection tools that flag anomalies in budget execution data. The platform was specifically piloted for corruption prevention and includes citizen feedback interfaces for reporting suspicious transactions.

Frequently asked

Quick answers

What does this platform cost to deploy?

OpenBudgets.eu is open-source software, so there are no licensing fees. The project was funded with EUR 2,981,000 in EU contributions for development. Deployment costs would depend on your infrastructure and integration needs, but the SaaS model was designed to minimize setup overhead for public administrations.

Can this handle data at the scale of a national government?

The platform was designed to serve thousands of public administrations and millions of citizens, according to the project objectives. It was tested in at least 3 municipalities in Spain. The semantic data model supports integration across different public sector levels — local, regional, and national.

Who owns the intellectual property? Can I build on this commercially?

The platform is explicitly open-source. This means you can fork, modify, and build commercial products on top of it. Fraunhofer (Germany) coordinated the project with 9 partners across 7 countries, so IP is distributed across the consortium under open-source terms.

What data formats does it support?

The platform includes semantic lifting tools that convert multi-format budgetary data into RDF (a standard linked data format) using the Data Cube Vocabulary. It handles heterogeneous input formats and includes automated data cleaning, enrichment, and quality improvement pipelines.

Is the platform still maintained and operational?

The project ended in October 2017. Based on available project data, the final integrated platform was delivered as a working product. However, ongoing maintenance status would need to be verified with the consortium, as EU-funded projects often require separate sustainability plans after the funding period.

Does it comply with EU open data regulations?

The platform was specifically designed for financial transparency in the public sector and aligns with EU open data directives. It uses standardized vocabularies (Data Cube, SKOS) and linked data principles, which are consistent with EU requirements for public sector information reuse.

What kind of analytics does it offer beyond basic visualization?

Beyond visualization, the platform includes data mining and statistical analytics tools for trend discovery, pattern detection, and budget forecasting. It also supports comparative analysis across different datasets, enabling cross-municipality or cross-country budget comparisons. The 52 deliverables produced include dedicated reports on these analytical capabilities.

Consortium

Who built it

The consortium of 9 partners across 7 countries (Belgium, Czech Republic, Germany, Greece, Spain, France, UK) is led by Fraunhofer, one of Europe's largest applied research organizations. The mix includes 3 research institutes, 2 universities, 1 industry partner, and 3 other organizations, with 1 SME. The low industry ratio (11%) reflects the public-sector focus — this is civic infrastructure, not a commercial product play. However, Fraunhofer's involvement signals engineering rigor, and the geographic spread across 7 EU countries means the platform was designed for cross-border interoperability from day one.
