How Losing My Typora License Led to Building My Own Markdown Editor

When Typora suddenly asked for a license key and showed a usage-limit error, the author decided to build a new Markdown editor.

The first version was a cross-platform desktop app built with Electron, React, and TypeScript, using secure IPC between the main and renderer processes.

The app was later rewritten in Rust, and distributable builds for both versions were released as open source.

The story shows how a product frustration can become a full replacement tool, while also highlighting secure desktop app architecture choices.
