Our Verdict
Both platforms use generative design to explore site possibilities, but they target different stages and users.
**Choose Autodesk Forma (formerly Spacemaker) if:** You're an architect or urban planner wanting deep environmental analysis (sun, wind, noise) integrated with the broader Autodesk ecosystem. Forma excels at sustainability-focused optimization.
**Choose TestFit if:** You're a developer or feasibility analyst who needs to test building configurations rapidly. TestFit's speed in generating unit mixes, parking ratios, and financial pro formas is unmatched.
Architects gravitate toward Forma for design quality. Developers prefer TestFit for decision speed. On large mixed-use projects, using both (TestFit for feasibility, Forma for optimization) delivers the best results.
