No more bespoke APIs. No glue code. Just fast, interoperable access via tools you already use — QGIS, ArcGIS, web maps, Python, R, MATLAB, and more. Flux is a cheat code for building data products.

We built Flux to solve a core pain point: turning massive geospatial datasets into usable APIs was slow, brittle, and distracting. Flux makes it trivial for any data producer to become a data provider.

One of the best parts of this release is that it included contributions from over 30 people. After a period of slow development, the v3 refactor really managed to build momentum in the project. Special shout out to @normanrz and Davis Bennett for doing a big chunk of the work.
