Multi-agent framework that simulates a software company to build apps from a single prompt
MetaGPT is an open-source multi-agent framework that simulates an entire software company with AI agents acting as product managers, architects, engineers, and QA testers. Given a single-line requirement, it outputs user stories, competitive analysis, requirements, data structures, APIs, executable code, and documentation. Built on the philosophy that Code = SOP(Team), MetaGPT uses carefully designed Standard Operating Procedures to guide specialized LLM agents through structured development workflows. The commercial product, now called Atoms (formerly MGX), provides a hosted platform for natural language programming with credit-based pricing.
