Following in the footsteps of the 0.6.0 release of the STAC spec, we are happy to release STACLint: An online validation tool for STACs.

If you are new to STAC or need a refresher please check this out.
If you are putting geospatial raster data on the web, you should probably be using STAC!

With this online tool, you are able to validate STAC catalogs, collections, and items by supplying either a URL or JSON. The tool will crawl nested catalogs and report any errors it finds as it crawls through. We have a timeout on the tool right now so it may not work for large catalogs. For those, we recommend our STAC Validator that can be run locally.


We have a number of additions for both tools coming down the pipeline including validating STAC extensions and JSON linting. We will be constantly updating the tools so please check back regularly.

A BIG thank you to the team here at Sparkgeo who worked hard on getting these released and to the STAC community for collaborating on a much needed specification for the new age of remote sensing.

These are exciting times for geospatial!
