Show HN: I made a tool to merge multiple JSON files online – free and fast

It’s fast, free, and doesn’t require any sign-up. Just upload your files, and it merges them into one clean JSON output.

I made this because I kept running into small but annoying JSON merging tasks while working on side projects — especially when dealing with API responses, config files, or datasets. Most existing tools were either CLI-only, full of ads, or had weird size limits. So I built my own.
