In Replit, the hinge question is whether the generated app correctly implements authentication, authorization, and data isolation in code. That typically means the agent must create and wire up middleware, session handling, database queries, and any row-level constraints the stack depends on, and the builder still has to inspect whether those mechanisms are actually correct. Replit is strong when that ownership is a feature, because you can access the repo, the runtime, and the deployment setup directly; it is weak when the buyer expected permissions to be product infrastructure rather than code to supervise.
In Softr, the same hinge question is handled at the platform layer through user groups, visibility rules, and data-source permissions rather than generated auth files. The practical difference is that the builder configures who can see what in the app settings and connected data model, instead of prompting an agent to rewrite access logic after every scope change. For a client portal, that matters because the maintenance burden stays in configuration, not in a growing security-critical code surface.
