As answered by people managing ZIP Code API and UltraEdit.
UltraEdit's answer:
UltraEdit is a native desktop application built primarily with C/C++ technologies, with an embedded JavaScript scripting engine and platform-specific components for Windows, macOS, and Linux.
UltraEdit's answer:
UltraEdit combines the power of a professional text and code editor with exceptional performance for demanding workflows. It is particularly strong at handling very large files, advanced search and replace, column/block editing, and complex text and data manipulation. Unlike many free or community-maintained editors, UltraEdit is commercially maintained and supported, making it suitable for critical and security-sensitive work.
UltraEdit's answer:
UltraEdit is built for developers, IT professionals, engineers, data professionals, and technical users who regularly work with code, logs, configuration files, structured data, or very large files. Its users range from individual professionals to large enterprises, including organizations in financial services, healthcare, government, technology, and other security- or reliability-sensitive industries.
UltraEdit's answer:
UltraEdit is designed for users who need more than a lightweight editor. It offers reliable large-file performance, powerful search and editing tools, built-in capabilities for working with code and data, and commercial support. It is a strong fit when performance, reliability, security, and long-term maintenance matter more than simply having a free editor.
UltraEdit's answer:
UltraEdit began in 1994 when engineer Ian D. Mead created a Windows text editor, originally called MEDIT, as a personal programming project and alternative to Notepad. After releasing it through CompuServe as shareware, the editor quickly attracted both individual and corporate users. More than 30 years later, UltraEdit has grown into a suite of professional editing tools with more than 4 million users worldwide.
