uCalc
Charlotte, North Carolina, United States
What it is
uCalc is a C++, C#, and VB SDK for evaluating expressions and transforming structured text. Its Fast Math Parser handles expressions defined at runtime, including those with custom variables, functions, and operators, and supports parsing once for repeated evaluation. The Transformer tokenizes text before matching and is designed for code refactoring, linters, and data transpilation. A String SDK adds mutable, token-aware search and replace, live substring views, and chainable text operations. The SDK is listed for Windows, macOS, and Linux and is offered through NuGet as a package for those systems. A Visual Studio extension provides token-aware search and transformation inside the IDE. Community access is free for hobbyists, students, nonprofits, solo developers, and small businesses below $100,000 annual gross revenue. Commercial SDK licensing is listed at $695 a year or $$1,295 one-time. License seats apply to developers actively writing code, while compiled products may be distributed royalty-free without platform-count fees. The maker cautions that the current preview lacks all safeguards for untrusted input and advises against production use on such input.
