From the beginning we have been committed to using open source software as our software development base. To develop mission critical tools for our partners we need the security, power, flexibility, and sustainability that only open source software can provide. In particular, we specialize in developing websites and applications with Node.js, rendering maps with TileMill and Mapnik, scaling databases with CouchDB, managing shape files with QGIS, and visualizing data with a variety of open source graphing libraries. Our technology toolset is always growing and changing to meet our evolving needs. Our team consistently contributes to many of these projects to push the limits of the possible and strengthen the wider open source community.
