Free Token.dev Alternative
Token.dev is a straightforward JWT decoder and generator that allows you to paste a token to decode it or create new tokens by providing header, payload, and signature information. The tool offers basic JWT functionality in a minimalist interface with no signup required. While Token.dev is simple and effective, it includes advertisements and external links that can distract from the core task of decoding tokens. If you want a completely ad-free, distraction-free JWT decoder with a privacy-first approach, Fixie offers a cleaner alternative.

Why Choose Fixie?
Token.dev is a practical JWT decoder and generator with a simple premise: paste a token to decode it, or fill in header/payload/signature fields to create a new one. For developers who need both decoding and basic token generation, Token.dev covers both use cases in one tool. The interface is straightforward and doesn't require any technical knowledge beyond understanding what a JWT is.
However, Token.dev includes advertisements on the page, which can be distracting when you're trying to focus on debugging authentication issues or inspecting token contents. The presence of ads also raises questions about whether the site tracks user behavior or collects analytics data. Additionally, the token generation feature requires manual input of the signature section, which isn't practical for most use cases (signature verification typically requires cryptographic libraries, not manual pasting).
Fixie's JWT Decoder & Inspector is completely ad-free and distraction-free, focusing exclusively on the core task: decoding JWT tokens to inspect their contents. No ads, no external links, no newsletter signups, no cookie banners — just a clean interface that shows you the decoded header, payload, and claims immediately. While Fixie doesn't offer token generation (a feature Token.dev has), most developers use decoders for inspection rather than creation. For token generation in real projects, libraries in your programming language (PyJWT, jsonwebtoken, etc.) are more practical than manual web forms. Fixie processes everything 100% client-side with no server communication, ensuring your tokens never leave your browser. No signup, no tracking, no ads — just fast, private JWT decoding.
How to Use JWT Decoder & Inspector
Step 1: Visit the JWT Decoder
Go to fixie.tools/jwt — no signup, no ads, no distractions.
Step 2: Paste Your Token
Copy your JWT token from your application or API and paste it into the input field. Fixie automatically strips 'Bearer ' prefixes if present.
Step 3: View Decoded Data Instantly
See the decoded header (algorithm, token type) and payload (claims, user data, expiration) formatted as clean, readable JSON. All decoding happens in your browser.
Step 4: Inspect Claims and Expiration
Review all claims in the token, including standard ones (iss, sub, aud, exp, iat) and any custom claims specific to your application. Check expiration timestamps to verify the token is still valid.
