From my experience with TestFit, I found it excels at accelerating early-stage building design by automating complex site feasibility and massing analysis. The no-code interface makes it accessible to developers and planners who may not have architectural expertise, which is a significant advantage in speeding up project planning. However, the tool is primarily focused on multifamily and commercial buildings, so it may not suit all project types. Also, pricing transparency could be improved for easier evaluation. Overall, if you need rapid, data-driven building massing and feasibility insights, TestFit delivers efficient and practical results.
