RST Software

RST Software Services helps organizations modernize legacy systems and rethink how they build software. The company combines platform modernization, PowerBuilder migration, AI-native engineering, and on-demand specialists to turn complex, difficult-to-change applications into flexible products designed for growth. Its PowerBuilder services move desktop systems toward secure, cloud-based web platforms through phased delivery intended to support business continuity and reduce risk. RST also develops web and mobile applications, bringing AI into engineering workflows rather than treating it as a standalone add-on.

A core offering is RST CodeLens, an AI-powered platform that analyzes legacy code, uncovers dependencies and technical debt, and helps teams assess migration costs and plan modernization. The company says the tool can help rewrite legacy code up to 70% faster. RST’s modernization framework pairs proven processes with AI-enabled tools and an enterprise-ready approach, reflecting its view that technology alone is not enough to transform an organization. For teams with skills gaps, RST provides short- and long-term engineering specialists without the need for traditional hiring.
