CityBldr is for developers who want buildable units, rents and assemblage math on a site; Plotzy is the broader parcel, zoning and owner search at published prices for brokers and land teams.

Plotzy and CityBldr both use AI to find development opportunities, and both count land acquisition teams and developers as core users. CityBldr goes deep on the development case: it calculates buildable units for a site, shows market rents by location, finds assemblage opportunities with its Assemblage AI, and includes a CRM for the resulting leads, on quote-based pricing. Plotzy goes wide: 150M+ parcels across 3,200+ counties with two-level zoning on each, filters for permitted use, lot size, owner type and sale date, a Zoning AI chat, owner contact lookup, folders and CSV export, at $180 or $300 a month with a 7-day trial.
CityBldr wins when the buyer is a multifamily or commercial developer whose first question is how many units pencil here. Buildable-unit math, rent context and assemblage detection are real work that Plotzy does not do, and the built-in CRM keeps the pipeline in one place. Coverage varies by market and pricing requires a conversation.
Plotzy wins when the job is broader than one development thesis: a land broker covering a county, an industrial buyer screening parcels by zoning, a retail team hunting corner sites, or anyone who needs owner contacts and an export more than a pro forma. Published month-to-month pricing and a no-card trial matter to smaller teams. Plotzy is still labeled beta, has no buildable-unit or rent modeling, and its sub-level zoning depth varies by municipality.
Pick CityBldr for development feasibility on candidate sites. Pick Plotzy to find the candidates and their owners in the first place; some teams use Plotzy to source and CityBldr to underwrite.
No. Plotzy gives you parcel attributes and two-level zoning so you can screen sites; buildable-unit and rent calculations are CityBldr features, and feasibility tools such as TestFit go further.
