🛠️ The Developer’s Secret Weapon for JWT Tokens — Free Online Decoder for Make
🚀 What I Built
As someone working with APIs and automation, I constantly run into JWT tokens — especially when building flows in Make. Whether it's Auth0, Firebase, custom OAuth, or third-party APIs, these tokens are everywhere.
So I built something simple but powerful:
🔐 A Free, Secure, Client-Side JWT Decoder and Encoder Tool

🔎 Why I Built It
Most online JWT tools either:
- Send your tokens to a backend 🤨
- Only support decoding (not encoding) 🔻
- Don’t support RS256/ES256 or modern algorithms
I wanted a tool that:
- Decodes and encodes JWTs
- Supports HS256, RS256, ES256 and more
- Works 100% client-side for security
- Is fast, responsive, and dark-mode ready
⚙️ How It Works in Make (Real Use Case)
Imagine you call an API with an HTTP module and receive a JWT in the response header or body. This decoder helps you:
- ✅ Paste the JWT into the tool
- ✅ Instantly view the decoded header, payload, and signature
- ✅ Understand claims like
exp,iat,sub,aud, and more - ✅ Encode and sign new tokens with a custom payload (perfect for testing and development)
It’s especially helpful for debugging flows, inspecting authentication tokens, or building OAuth integrations inside Make.
🧰 Features
- ✅ Secure, client-side decoding
- ✅ JWT Encoder with secret input and random key generator
- ✅ Support for HS256, RS256, ES256, and more
- ✅ Clean UI with dark mode toggle
- ✅ Copy-to-clipboard, clear-all, and live decoding on input
