JWT.io alternative
Best JWT.io Alternative: XSular Tools JWT Decoder
JWT.io set the standard for decoding JSON Web Tokens in the browser. XSular Tools matches the essentials—decode, inspect, and generate signed tokens—while staying ad-free and bundling the JWT workflow with a full free toolkit for developers and designers.

Why developers switch from JWT.io
If you only need to paste a token and read the header and payload, both sites get the job done. Where XSular Tools pulls ahead is the overall experience: no banner ads, no account prompts, and the same privacy promise across every tool—your token never leaves your browser.
After you verify a signature or draft test claims, you can jump to our JSON formatter, hash generator, or URL encoder without opening another tab. For teams that mix API debugging with content and design work, that single hub saves time.
What you get with XSular JWT Tool
Our JWT decoder shows header, payload, and signature verification with clear error messages. The generator builds sample tokens with configurable secret length, expiration presets, and copy-ready Authorization headers.
Everything runs locally with the Web Crypto API where supported, so production secrets are not sent to our servers—because we do not operate an ingestion API for tool input.
