Show HN: I built a native macOS Markdown viewer 100% with AI coding agents
TL;DR
A developer built a native macOS Markdown viewer using Tauri 2 (Rust + webview) — without writing a single line of code by hand. Every line of Rust, CSS, and JavaScript came from AI coding agents (pi. dev/Qwen and Claude Code), driven only by a high-level brief and iterative back-and-forth. The app supports GitHub Flavored Markdown plus Obsidian features (wikilinks, callouts, Mermaid diagrams), uses HTML sanitization for safety, and stays at a few megabytes.
Nauti's Take
Compelling proof of how far AI coding agents have come: a full native macOS viewer built with Tauri, Rust and webview, without a single human-written line. For solo developers that is a real opportunity to ship ambitious projects on a small time budget.
The catch: without deeper grasp of architecture, security and sanitization, every agent-generated codebase stays a black box — maintenance and debugging then hang on the next model upgrade.
