GeneXus

GeneXus is an AI-powered low-code platform for creating and evolving mission-critical software from a Knowledge Base. Its deterministic generators produce applications from a model for multiple technologies and platforms, including native Android and iOS apps. An Angular generator supports web and mobile front ends, while.NET and Java generators cover web applications and backends. GeneXus for Agents lets AI agents work with Knowledge Base objects through skills, a CLI, and an MCP Server; the GeneXus engine validates changes. The platform supports REST and SOAP APIs, OpenAPI documentation, custom code integrations, and connections to external systems and databases. Named connections include OpenAI, AWS, Azure, Google Cloud, Apache Kafka, and Azure Service Bus. GeneXus describes security as built into its generation process and says integrations support OAuth, encryption, and secure communication channels. Deployment options include cloud, on-premises, multi-cloud, and hybrid environments. Founded in 1988 and headquartered in Montevideo, Uruguay, GeneXus lists a free plan at free and a free trial. It presents the platform for enterprise IT departments, software houses, startups, and mission-critical business applications.
