Replica

Replica is a San Francisco-based data platform for the built environment, spun out of Alphabet's Sidewalk Labs in 2019, that operates a nationwide activity-based travel model. Its analytical engine combines public data (US Census/ACS, GTFS transit feeds, OpenStreetMap road networks, land-use records, state traffic counts) with licensed private data (de-identified aggregate mobile location, credit transaction and driving-behavior data) to synthesize a privacy-preserving simulated population and a complete trip table for the United States. Products include Places (seasonal, high-fidelity activity-based travel model), Trends (weekly near-real-time mobility and land-use data), Safety Hub, Safe Streets Planner, and a suite of workflow applications used by state DOTs, MPOs, transit agencies, cities and counties. Data is consumed through the Replica Studio web platform, CSV export and direct database access; Replica publishes documented dataset schemas at documentation.replicahq.com but no public developer REST API, SDK or developer portal.

Replica is profiled on the APIs.io network. Tagged areas include Company, Data, Mobility, Transportation, and Geospatial.

Replica’s developer surface includes documentation, getting-started guide, support, engineering blog, changelog, and 33 more developer resources.
