# 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.

---

## Summary

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. The interesting part isn't the feature list — it's the build process as a real test of agent-driven software development.

## 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.
