To help more researchers use CARTO to drive their geospatial data, we have released the R client library. [Fork it on GitHub!](https://github.com/Vizzuality/cartodb-r)
This demo app authenticates with your CARTO and shows how to perform read and write queries using the SQL API. [Fork it on GitHub!](https://github.com/Vizzuality/cartodb-nodejs)
The PHP library provides a wrapper around the SQL API to get PHP objects straight from SQL calls to CARTO. [Fork it on GitHub!](https://github.com/Vizzuality/cartodbclient-php)
CARTO provides access to the SQL API through [CARTOframes](https://github.com/cartodb/cartoframes/), a package built with data scientists in mind, and [CARTO Python SDK](https://github.com/cartodb/carto-python/), built to support application development. Install cartoframes with `pip install cartoframes` and the SDK with `pip install carto`.
.NET library for authenticating with CARTO using an API Key, based on work started by [The Data Republic](http://www.thedatarepublic.com/). [Fork it on GitHub!](https://github.com/thedatarepublic/CartoDBClientDotNET)
Clojure library for authenticating with CARTO, maintained by [REDD Metrics](http://www.reddmetrics.com/). [Fork it on GitHub!](https://github.com/reddmetrics/cartodb-clj)
Objective-C library for interacting with CARTO in native iOS applications. [Fork it on GitHub!](https://github.com/jmnavarro/cartodb-objectivec-client)
