Hi Product Hunt! 👋 I’m Kotysoft, the solo developer behind Giant JSON Viewer. To be honest, I didn’t build this because I was stranded on a desert island with a 5GB log file. I built it because I’ve always had a childhood dream of releasing a truly useful public application—something that solves a hard engineering problem, not just another "To-Do" app. While researching ideas, I successfully identified a major pain point: Large JSON files. I deal with JSON daily, and I know the frustration of browser tabs hanging or editors freezing even on a powerful desktop. On mobile? It was impossible. Most viewers crash instantly with anything over 50MB. So I decided to tackle it. Giant JSON Viewer is my answer. It’s not a web-wrapper; it’s a native Android app powered by a custom Rust engine. What makes it different? It handles the unexpected: I’ve personally stress-tested it with 3GB+ files. It doesn't crash. Smart Indexing: It scans the file structure once, so you can jump around instantly. Data Tools: It has a graphical query builder, and you can export filtered data to SQL or CSV. This is my first real public launch. My goal today is simple: Awareness and Feedback. Does it work for your use case? What feature is missing that would make this your "daily driver"? Did you find a file that breaks it? (I want to know!) I’d love to hear your thoughts. I’ll be hanging out here all day to answer questions! Kotysoft
