QGIS is a gold standard to verify you tools works fine and data is in a correct format ...

if you are a web based first, you have even better options to build and extend

kepler, protomaps, maplibre-gl-js

https://kepler.gl

https://protomaps.com

https://github.com/maplibre/maplibre-gl-js

the rest can be found on great Qiusheng Wu’s (aka @giswqs) Geo/GeoAI tutorials channels and repos

but what really amazed me is how geo spatial support is growing inside of databases recently

https://duckdb.org/docs/stable/core_extensions/spatial/overv...

all mighty postgis https://postgis.net/docs/manual-3.5/postgis_cheatsheet-en.ht...

https://sedona.apache.org/latest/

https://geoparquet.org/releases/v1.0.0/

and many unlocked dataset compare to other industries

https://www.openstreetmap.org/

https://hub.arcgis.com/search

lot great webtools are comming for sure and you still can be 100% of most of your geospatial pipeline

p.s. want to extend the above list with self-hosted tools with minimum or none dependencies on paid APIs, and recommendations are greatly appreciated
