GUI JWT encoder / decoder - Local, private, easy.

A lightweight, open-source GUI tool for JWT encoding and decoding, designed to support testing around authentication and authorization in app development.
## Usage options

```sh
npm install -g jwt-encde
npx jwt-encde
```
- Install via Rust cargo
```sh
cargo install jwt-encde
jwt-encde

- [Assets](https://github.com/nabbisen/jwt-encde/releases/latest) in GitHub Releases are avalilable
## 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 🌱
