Description

This app allows you to inspect, analyze, and edit JWT payloads as JSON, and easily convert test JSON data into JWTs for development and debugging purposes.

Key features

Runs entirely offline, unlike online tools
- It strongly ensures security and privacy. No data ever leaves your machine.
Built with a low-memory, high-performance architecture
Available as a cross-platform binary for Windows, macOS, and Linux

Additional features included

Syntax highlighting for JSON to improve readability
Disabled states for unavailable actions to prevent accidental operations
A built-in helper tool for analyzing UNIX timestamps within JSON data

Note: This app does not support JWT signing or token introspection

In real-world systems, signing keys and token validation are typically managed by IDaaS. They should be verified through actual integration with the provider.

Open-source, with care

This project is lovingly built and maintained by volunteers. We hope it helps streamline your work. Please understand that the project has its own direction — while we welcome feedback, it might not fit every edge case 🌱
