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.
