Open-Source Sustainability Reporting Workspace

– Structured reporting workflows aligned with the EFRAG VSME framework
– Self-hosted with full control of reporting data and infrastructure
– Deterministic validation and export (JSON, XLSX, PDF) – no AI-generated reporting logic
– Materiality management and auditable reporting workflows
– Free and open-source

How The App Works

LibreVS is designed for practical and transparent sustainability reporting workflows.

Structured VSME Workspace

LibreVS provides a structured workspace for sustainability reporting aligned with the VSME framework.
Instead of generic document handling, the application organizes reporting into clear sections, workflows, and reporting modules designed for practical ESG work.

Self-Hosted & Local Control

LibreVS is designed to run in self-hosted environments, giving organizations full control over their reporting data and infrastructure.
The platform supports local-first workflows and aligns with European digital sovereignty principles by reducing dependency on external SaaS platforms.

Deterministic Reporting Workflow

The application focuses on transparent and deterministic reporting workflows rather than opaque automation.
Users work directly with structured sustainability data, reporting logic, and documentation in a way that remains inspectable and auditable.

Open-Source & Extensible

LibreVS is released as an open-source project to encourage transparency, collaboration, and long-term adaptability.
Organizations and contributors can inspect the codebase, self-host deployments, and extend the platform to fit different reporting and operational needs.

Why is LibreVS free?

LibreVS is released as free and open-source software because sustainability reporting infrastructure benefits from transparency, reproducibility, and broad access.

The goal is to lower the barrier for organizations working with the EFRAG VSME framework and to enable practical experimentation with structured sustainability data without vendor lock-in or licensing constraints.

The project is built on the assumption that reporting infrastructure should be inspectable, self-hosted, and fully under the control of the organization using it.

LibreVS may evolve into additional services around implementation, hosting, and support, but the core reporting engine will remain open-source.
