TestFit vs Delve by Sidewalk Labs vs Giraffe Technology

TestFit is an AI-powered site planning and real estate feasibility software that helps architects, developers, and contractors generate rapid layout studies, parking plans, and early-stage design options. With parametric tools, real-time iteration, and integrations with platforms like Revit, SketchUp, and AutoCAD, TestFit helps teams move faster through feasibility workflows before detailed design begins. Teams comparing TestFit AI software, pricing, free trial options, and alternatives often evaluate it for faster planning, yield studies, and pre-design decision-making.

Delve was a generative-design tool from Sidewalk Labs that used AI to evaluate thousands of site-planning scenarios for real estate developers and urban planners. Sidewalk Labs was folded into Google in 2021-2022 and Delve's technology was absorbed into the Google Earth team, so it is no longer offered as a standalone product.

Giraffe is a web-based platform that helps real estate developers, architects and planners run feasibility studies, site analysis and generative design, from a single site up to a full portfolio. It connects spatial data layers, automates massing and yield calculations, and lets teams collaborate on development decisions in real time.
