Notepad4 is a lightweight text editor for Windows that provides syntax highlighting, code folding, auto-completion, and API lists across many programming languages and document types.
The tool addresses the need for a fast, minimal text editor with modern language support by building on the Scintilla editing component. It evolved from earlier projects by rewriting their foundations in modern C++ to improve maintainability and performance. The editor bundles matepath, a file browser plugin, directly into the installation, eliminating the need for separate downloads.
Notepad4 suits developers who want a responsive alternative to heavier IDEs for quick editing tasks, code review, or working with multiple file types. It works well for those already familiar with Notepad2 or Notepad2-mod who want an updated codebase with contemporary language support. The project explicitly positions itself as a modernized continuation of those earlier editors, making it a natural choice for users seeking their successors rather than a complete replacement for full-featured development environments.
Development activity shows consistent attention to build infrastructure, with automated builds generated across multiple compilers and platforms including ARM64 support. The project maintains active CI/CD pipelines that produce development artifacts regularly, indicating ongoing integration work. Wiki documentation exists to guide users through building from source, suggesting the maintainers support community compilation efforts alongside providing prebuilt binaries.
