Free JWT.ms Alternative

JWT.ms is a simple JWT decoder created and maintained by Microsoft, designed primarily for debugging Azure Active Directory and Microsoft identity platform tokens. The tool decodes JWTs entirely in the browser, showing header and payload claims with automatic detection of Microsoft-specific claim types. While JWT.ms is lightweight and privacy-focused, it's visually branded with Microsoft's identity platform and includes links to Azure documentation. If you work outside the Microsoft ecosystem or want a completely neutral JWT decoder with no platform-specific branding, Fixie's JWT Decoder & Inspector offers a simpler alternative.

Why Choose Fixie?

JWT.ms is an excellent tool for developers working with Microsoft identity platform and Azure Active Directory. If you're debugging Azure AD tokens and need to understand Microsoft-specific claims like 'tid' (tenant ID), 'oid' (object ID), or 'roles', JWT.ms provides helpful explanations and links to Microsoft documentation. The tool is minimal, fast, and processes tokens entirely client-side for privacy.

However, JWT.ms is designed specifically for the Microsoft ecosystem. The interface includes Microsoft branding, Azure Active Directory references, and links to Microsoft identity documentation. If you're working with JWTs from non-Microsoft identity providers (Auth0, Firebase, custom implementations), the Microsoft-specific context can be confusing or irrelevant. The tool doesn't offer signature verification or token generation — it's purely a decoder.

Fixie's JWT Decoder & Inspector is platform-neutral, with no branding from any identity provider. Whether you're working with Azure AD, Auth0, Firebase, Okta, or custom JWTs, Fixie decodes all tokens the same way: header, payload, standard claims, and expiration timestamps in clean, readable JSON. No ecosystem-specific claim hints, no platform documentation links — just straightforward decoding. Like JWT.ms, Fixie processes everything 100% client-side, ensuring your tokens never leave your browser. No Microsoft account required, no Azure knowledge needed, no vendor lock-in — just a simple, independent JWT decoder for any identity platform.

How to Use JWT Decoder & Inspector

Step 1: Open the JWT Decoder

Navigate to fixie.tools/jwt — no Microsoft account, no Azure subscription, no platform signup required.

Step 2: Paste Your JWT Token

Copy your JWT token from your application, API, or authentication flow and paste it into the input field. Works with tokens from any identity provider (Azure AD, Auth0, Firebase, custom, etc.).

Step 3: View Decoded Header and Payload

Instantly see the decoded header (algorithm, token type) and payload (claims, user info, expiration) formatted as JSON. All processing happens client-side in your browser.

Step 4: Inspect Claims

Review standard claims (iss, sub, aud, exp, iat) and any custom claims specific to your application or identity provider. Check expiration timestamps to verify token validity.

Frequently Asked Questions

Is Fixie's JWT decoder as private as JWT.ms?
Yes. Both tools process JWT tokens entirely client-side in your browser. Neither tool sends tokens to a server or stores them anywhere.
Can I decode Azure Active Directory tokens with Fixie?
Yes. Fixie decodes all JWT tokens regardless of the identity provider. However, JWT.ms offers Microsoft-specific claim explanations and Azure documentation links that Fixie doesn't provide.
Does Fixie verify JWT signatures like JWT.ms?
No. JWT.ms also doesn't verify signatures — it only decodes tokens. If you need signature verification, use JWT.io instead.
Why use Fixie instead of JWT.ms?
Fixie is platform-neutral with no Microsoft/Azure branding or ecosystem dependencies. If you work with multiple identity providers or want a completely independent decoder, Fixie offers a cleaner experience.
Can I generate JWTs with Fixie or JWT.ms?
No. Neither tool generates tokens. For token generation, use JWT.io or a library in your programming language.
