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.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/replica: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
