Hi PH 👋 I built Pandia because every JSON tool I tried either lagged on large files or wanted me to paste sensitive data into a website. Pandia is a native app (Rust + Tauri) that streams the file with zero-copy slicing — so a multi-GB JSON opens instantly, nothing is uploaded, and you get five views, type generation for 9 languages, diff, validate, repair and convert in one place.
Free and open source (Apache-2.0). Happy to answer anything about the app!

Opening multi-gigabyte JSON files locally without uploads is genuinely useful. What pushed you to optimize for huge files instead of building another general JSON editor?

@aryan787544 The main reason was having to read JSON log files, database dumps, and massive data exports. Since most standard editors crash when I try to load the files, I wanted to solve this specific pain point without sacrificing privacy

@hendurhance That's a very real pain point, and it's nice to see someone solving it without compromising privacy.
Feels like there's more to discuss than fits in a Product Hunt thread. If you're open to it, what's the best email to continue the conversation?
Love how fast it opens huge files locally - huge win over cloud tools. One thing I'd love: a built-in JSONPath or jq-style query bar at the top so I can jump straight to nested data without manually expanding the tree. That would make diffing giant files way less of a chore.

@elife1154371 We currently support jq-style query bar, but it is more of an input wizard.
