Hybrid Multi-Agent Framework for Enterprise Web Application Generation

There are always repeatable functions like building similar CRUD workflows, implementing authentication layers, role based access control and admin interfaces for various projects on an enterprise web application, and different con-ventions can be used by different developers or code-bases. AI-powered coding tools recently emerged that promise to make this possible, but existing studies have shown that automated LLM-based code generation, vibe coding and free-running multi-agent pipelines have difficulty maintaining consistency between relational schemas, backend APIs, and frontend interfaces as applications grow in size, and become a maintenance night-mare. The main idea is that structural code which can be programmed from an application data model does not need to be probabilistic (only truly ambiguous decisions are language-model decisions such as interpreting the relational semantics, or resolving ambiguous requirements). We build this insight into a system called CodeCraft, where a Prisma schema and its Data Model Meta Format (DMMF) representation are the only source of truth for deterministic generators to generate backend APIs, frontend manifests, RBAC structures and database seeders, while a LangGraph six-agent multi-agent orchestration pipeline (from requirements engineering, schema design, orchestration, backend generation, frontend generation, and containerization) can only be used to clarify requirements, validate schema, and make decisions that cannot be made structurally. Generated systems have a consistent schema representation, as opposed to the prompt-driven tools which are used for each individual file. In all the applications it is demonstrated that schema validation slashes the number of automated iterations required to correct schemas to 2-4 and the end-to-end generation generates deploy-able, containerised applications after requirements and schema approval (no manual effort required). Comparative engineering indicates that the development effort is reduced by 70–80%, compared to manual implementation, but this has not yet been substantiated with a controlled external study.
