👋 Hey! I'm Chung Ho, a Tech Lead from Vietnam and the maker of stdout.

🪲 The problem I was scratching
As a developer working with APIs and data pipelines daily, I kept copying sensitive JSON into online tools to format or validate. Each time, a little voice asked: "What if this tool logs my data?"

I needed utilities that just work — offline, private, and fast. So I built stdout for myself. Then I realized: maybe others have the same itch.

✨ What makes stdout different
- 🔒 Local-first by design: Everything runs in your browser. No backend. No data leaves your machine.
- ⚡ Zero friction No signup, no install. Open the link and start working.
- 🧰 59 utilities in one place: JSON/XML formatter, encoding converters, regex tester, UUID generator, and more — all in a single, searchable workspace.
- 🌐 Offline-ready: PWA-enabled. Works even when your Wi-Fi dies mid-task.

🛠 Built with
- Vanilla JS + Web Components (no heavy framework)
- Service Workers for offline caching
- Simple, composable architecture — easy to extend

🙏 Why I'm launching here
I treat stdout as a product experiment: build fast, dogfood daily, and learn from real users. Your feedback will directly shape what I build next.
