JWTs are everywhere.
Modern applications use them for authentication, authorization, and session management.
Yet most developers rarely remember their exact structure until something breaks.
Today's featured utility inside Dev Suit is the JWT Decoder & Token Analyzer.
What is a JWT?
A JWT (JSON Web Token) consists of three parts:
Header.Payload.Signature
Each section is Base64 encoded.
A typical JWT looks like this:
xxxxx.yyyyy.zzzzz
At some point, every developer asks questions like:
• Why is authentication failing?
• Has the token expired?
• What permissions does this user have?
• Which claims are included?
• Is the issuer correct?
This is exactly where a JWT decoder becomes useful.
Common JWT Use Cases
JWTs appear in:
• OAuth workflows
• OpenID Connect
• API authentication
• Microservices
• Single Sign-On
• Identity providers
• Cloud applications
• Backend systems
Why I Built It
As a developer, I've copied JWTs into random websites countless times.
I wanted a clean utility that helps developers quickly inspect:
✅ Headers
✅ Claims
✅ Expiration dates
✅ User roles
✅ Audience values
✅ Issuers
Without needing external dependencies.
