OpenHEXA is an open-source, bilingual (EN/FR), collaborative data integration and analysis platform for public health, built by Bluesquare. It brings scattered data together, makes it shareable, and simplifies visualization and modeling, all in one platform designed for building data products that public health teams can rely on.
OpenHEXA is recognized as a Digital Public Good by the Digital Public Good Alliance and listed as a Digital Square Software Global Good, and it is an official DHIS2 Technology Partner.
OpenHEXA covers the full path from raw data to a decision-ready product, organized around 3 functions.
AI-assisted tools support pipeline development and the building of lightweight web applications directly inside OpenHEXA workspaces, and a Model Context Protocol (MCP) server connects major AI tools to the platform’s data.
OpenHEXA supports more than 18 integrations spanning health and supply chain systems, enterprise tools, and data formats: DHIS2, IASO, OpenLMIS, ODK, mSupply, Sage X3, SAP, PostgreSQL, Excel, CSV, Parquet, GCP Bucket, S3, GeoPackage, OpenRaster, WorldPop, and ERA5 climate data, among others. Where a connector does not exist yet, the OpenHEXA team builds it on demand.
Data engineers build, automate, and schedule pipelines, and curate datasets with less script maintenance to manage over time.
Data scientists explore data in reproducible, infrastructure-agnostic notebooks, using toolboxes built for public health work.
Domain experts run existing pipelines without writing code, and access and annotate datasets directly.
OpenHEXA is used by NGOs, Ministries of Health and international development partners. A few examples of what that looks like in practice:
In Niger, the Ministry of Health worked with Bluesquare through the Gates-funded RISP initiative to replace fragmented, non-integrated immunization data systems with automated monthly performance reports generated through OpenHEXA, now running at national, regional, and district levels.
In Côte d’Ivoire, the Ministry of Health, supported by USAID through the LSHPLA project, uses OpenHEXA to integrate order and delivery data from Excel, eSIGL, Sage X3, and PDF reports into a single workflow that detects stockouts and delivery delays across the pharmaceutical supply chain, including antiretroviral treatment.
LifeNet International, which supports more than 400 faith-based health facilities across 6 African countries, used OpenHEXA to bring together data previously scattered across Salesforce, Formyoula, Kobo Toolbox, Excel, Google Sheets, and Moodle into one monitoring and evaluation platform, with monthly and quarterly dashboards and built-in data quality checks.
Pathways, a platform led by Sonder Collective and funded by the Gates Foundation, relies on OpenHEXA as the data backbone behind more than 20 vulnerability-segmentation projects across 7 countries since 2019, centralizing survey data, segmentation outputs, and decision trees, and automating the pipelines that keep them current.
OpenHEXA’s source code is open, which means institutions are not locked into a single vendor and can inspect, adapt, or host the platform themselves. Secure workspaces and role-based access controls keep sensitive health data, including individual-level records, visible only to the people who need it. Flexible deployment options, including on-premises installation on national servers, support institutions that want to keep their data within their own infrastructure.
OpenHEXA is developed by Bluesquare, a Belgian company that builds data tools and provides technical assistance to ministries and public organizations, mostly in low- and middle-income countries. Across every project, the institutions Bluesquare works with, ministries of health, national programs, and partner organizations, lead the decisions; OpenHEXA is built to support that work.
