Pandia
Open multi-gigabyte JSON instantly — native, offline, free
Pandia is a fast, native JSON viewer & editor for macOS, Windows and Linux. It opens multi-gigabyte files instantly (no upload, no size limit), shows JSON five ways — Tree, Code, Grid, Graph, Compare — and generates types for 9 languages. Offline, private, free, open source.
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!
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.
The five different views for the same JSON is a really thoughtful touch. Most tools force you into one perspective, so letting me switch between Tree and Graph depending on what I'm trying to see just feels right. Solid execution.
