3D zoning, NYC-deep: RunEnvelope vs. Gridics
Gridics is a 3D zoning and development-analysis platform that maps parcels and visualizes development potential across many cities, and has expanded into New York. RunEnvelope is NYC-only by design, which is why its as-of-right output goes to architect-grade depth.
Gridics is a broad, multi-city zoning-code and 3D-analysis platform, often sold to municipalities and enterprises. RunEnvelope concentrates entirely on NYC, resolving the as-of-right envelope, City of Yes, air rights and sketch plans lot by lot, available as a single report from $149.

Frequently asked.
Is RunEnvelope a Gridics alternative for NYC?
For NYC feasibility, yes. Gridics is a multi-city zoning platform; RunEnvelope is NYC-native, producing an as-of-right FAR, 3D massing with sketch plans, City of Yes analysis and ZR citations for a specific lot.
Why choose an NYC-only tool over a multi-city one?
Depth. New York’s zoning is unusually complex: bulk packing, sky-exposure planes, quality-housing rules, City of Yes. A tool built only for NYC can encode those rules to architect-grade precision rather than generalizing across jurisdictions.
How do I try RunEnvelope?
Run a single report on any NYC address for $149 with no subscription. It’s the quickest way to compare its per-lot depth to a Gridics analysis.
