NGI0 Commons Fund
FiberQ QGIS plugin
Interoperable open tooling for fiber rollout — funded through NLnet’s NGI0 Commons Fund.
FiberQ is a free and open-source toolchain for designing, documenting and validating fiber-optic access networks — FTTH, GPON and the underlying duct infrastructure — inside the open QGIS ecosystem. The FiberQ QGIS plugin (GPL-3.0-or-later) has been in production since v1.0 in December 2025, with several feature releases since, and provides a dedicated infrastructure data model and repeatable workflows that take a design through to documentation and QA without ever leaving open formats. This grant funds the next major plugin release — schema migrations, automated topology and attribute validation with audit-ready reporting, performance work for large projects, automated tests with CI, and import/export tooling built on GeoPackage and GeoJSON, including a documented open project-interchange format for portable exchange between the plugin and other tools.
FiberQ Designer, a separate browser-based companion developed independently as a commercial product, interoperates with the plugin through this open interchange format.
What the grant funds
The grant supports the next major plugin releases, all on the same open codebase.
FiberQ — QGIS plugin (GPL-3.0)
- Schema migrations for clean upgrades
- Automated topology and attribute validation with audit-ready reporting
- Performance work for large projects
- Automated tests with CI
- Import/export for round-trip compatibility with FiberQ Designer (GeoPackage / GeoJSON)
Who it is for
FiberQ targets municipalities, smaller operators, contractors and engineering teams that today rely on proprietary CAD/GIS suites with non-portable data formats. The goal is an open data model these teams genuinely own — one that carries a fiber design from planning through to documentation and QA, and keeps it portable end to end.

Releases & downloads
Every funded work package ships as a tagged plugin release with published documentation, on the same open GPL-3.0 codebase. Newest first.
July 2026 · Released · GPL-3.0-or-later
v1.3.0 — WP1 · Data model & migrations
Project schema versioning, safe automatic migrations, and a stable per-feature identity (fiberq_uuid). Verified end to end on QGIS 3.40 (Qt5) and QGIS 4.2 (Qt6), with both new and migrated older projects.
- Per-project schema-version marker, mirrored into the GeoPackage
- Automatic, lossless, idempotent on-load migration of older projects (schema 0 → 1.0)
