summary
A simple Markdown Editor for Mac, mostly.
AI Coding is coming for us all.
I recently replaced my Mac and installed all the things on the new one. I was sure I had a Typora license somewhere and searched through all my email accounts, but I just couldn’t find it. Now should I pay NZD 28.83 again and get a new license? Or search for open source alternatives?
No! You know what I’ll do? I’ll have my AI coding agents make me my own Markdown Editor!
And one weekend later - I had my own Markdown Editor: MarkusDown! Or maybe that’s stupid, let’s style it as Mark-us-Down instead, now it’s a bit self-derogatory, almost funny! … Almost.
It’s built with Tauri v2 (essentially a better, faster, smaller, Rust-based Electron that I hadn’t even heard of) and React with TypeScript, Monaco Editor, and Vite for frontend bundling.
It features a clean split-pane interface with real-time preview, syntax highlighting and seamless scroll synchronisation.
And you can switch it to dark mode if you want.
I had to hand-hold the development a bit, but any semi-experienced dev could have done it.
Now who’s going to buy Typora if anyone can build something similar in a weekend?
Will it all come down to Marketing now? Or is a lot more good software going to be free? Are we going to get many, many great open source tools? Will this be any consolation when we’re all jobless, homeless, purposeless husks of our former selves shovelling coal for the billionaire owners of the big LLM data centres?
