Iskra is a lightweight, fast, and native x64 Unicode text editor for Windows 10 and 11, built from scratch using the Win32 API, Scintilla, and Lexilla.
With native Markdown support and real-time browser-based previews, Iskra merges the performance of raw text processing with the requirements of modern web authoring.
Beyond its core efficiency, Iskra offers a robust and expanding feature set, including but not limited to: extreme performance for large-scale text analysis, an advanced regex engine, smart find-and-replace, configurable auto-save, adjustable window transparency, visual customization, versatile export options, reliable print preview, and quick access to recent files.
Iskra is free for personal use.
