This comparison judges Same.new and Softgen on one concrete job: autonomous agency client work for a client portal or internal business app. That is the right test because these tools diverge at the exact point agencies get hurt: Same.new starts from visual replication, while Softgen starts from prompt-driven full-stack scaffolding.
That job exposes the failure modes that matter. A client project is not just a screen; it needs authentication, structured data, permissions, revisions, and a handoff that does not turn every change into a repair sprint. If a tool makes the UI easy but the logic brittle, or the logic quick but the styling painful, the margin disappears on day two.
