Announcing the Alpha Version of OpenSpending Next

We’re happy to announce that a new, improved version of OpenSpending is now being launched as an Alpha Version. OpenSpending Next provides a set of tools enabling users to visualise, analyse and publish budget and spending data - all based on the open Fiscal Data Package standard.

OpenSpending Next is designed, developed and maintained by Open Knowledge International and, as an open source project, also reflects the very valuable contributions of an active, passionate and committed community.

OpenSpending Next fills a gap in the lack of open tools that offer easy budget data publication, visualisation and analytics for individuals and organisations working with fiscal data, as well as provide a data model standard.

The aim of the project is to support the international open data community by offering a platform that makes it easier for civil society organisations, activists and journalists to see how and where public money is being spent. OpenSpending is also targeted to governments and any regional, local administration or municipality level to increase fiscal transparency.

The Fiscal Data Package standard unveils spending data and fiscal documents at all stages of the budget process by defining a common data model.

OpenSpending Next Alpha Release comes with core tools, including a fully working API:

  • OS Packager enables users to map any fiscal data against the standard, and create a Fiscal Data Package from CSV files with a simplified workflow. This package can be uploaded to OpenSpending API with just a few clicks.
  • OS Viewer lets users create and customise visualisations based on their budget and spending data. Treemaps, pie charts, bar charts, geolocation, line charts, tables, you name it!
  • OS Explorer allows discovering and exploring our rich collection of fiscal data sets.
  • OS DataMine: A rich analytical tool based on re:dash that allows performing deep queries into fiscal data.
  • OS API: This V3 API is almost entirely based on the excellent Babbage. This API also features a fully backwards compatible implementation of the OpenSpending V2 API for legacy apps that depend on it.


Since we started developing OpenSpending Next, we’ve been working in the following general areas:

This work has been also funded by Adessium Foundation as part of OpenSpending EU, a project that aims at making EU Budgets and Spending data, as well as EU Structural funds accessible to citizens, researchers, journalists and policy-makers.
