The JSON viewer
for Linux.
A native Linux app shipped as an AppImage, .deb and .rpm.
Pandia opens multi-gigabyte JSON without freezing, runs fully offline, and stays out of your way —
built in Rust, not Electron.
AppImage · .deb · .rpm · 64-bit · Offline · Apache-2.0
Native, lightweight, distro-friendly
Pandia is a native Linux application built with Rust + Tauri — it uses your
system’s webkit2gtk rather than bundling a whole browser, so the download is small and
startup is instant. Ship it as a portable AppImage, or install the .deb
/ .rpm for your package manager.

Multi-GB JSON opens instantly — no cap on opening or viewing.

Install on Linux
- AppImage —
chmod +xthe file and run it; no installation needed. - Debian / Ubuntu —
sudo apt install ./Pandia_*.deb. - Fedora / RHEL —

If a launch fails, install webkit2gtk from your distro’s repos. See the
installation guide for details.
Frequently asked questions
Which Linux package should I download?
Use the AppImage for a portable, distro-agnostic binary you can run anywhere; the .deb for Debian and Ubuntu; or the .rpm for Fedora and RHEL. All are 64-bit (x86_64).
What dependencies does it need?
Pandia uses webkit2gtk, which is available in every mainstream distro’s repositories. If a launch fails, install the webkit2gtk package for your distribution and try again.
Is the Linux JSON viewer free?
Yes — free and open source under Apache-2.0. No accounts, no telemetry, no paid tiers.
Can it open large JSON files on Linux?
Yes. There is no cap on opening or viewing — Pandia streams multi-gigabyte files and only loads the on-screen slice, so they open instantly.
