THE ZERO-UPLOAD STANDARD FOR DEVELOPER TOOLS
TokenInspectKit was engineered to solve a dangerous everyday practice: pasting production session tokens and API keys into arbitrary third-party cloud decoders.
The Fundamental Problem
Developers, devops engineers, and QA testers inspect JWTs dozens of times each day to troubleshoot expiration mismatches, check authorization roles, or diagnose failed authentication handshakes.
Historically, the default reaction has been to visit public web decoders. Unfortunately, many of these platforms are hosted by third parties that track user behavior, route token strings through remote proxies, or maintain backend request logs. When active tokens with production roles are transmitted to external servers, company data security policies are breached.
Our Client-Side Guarantee
TokenInspectKit eliminates this security exposure entirely:
- Zero Backend Infrastructure: There are no APIs, no serverless functions, and no databases backing TokenInspectKit. The application is compiled to static HTML, CSS, and client-side JavaScript.
- Web Crypto API: Cryptographic checks (such as HMAC HS256/384/512) utilize your device's native browser hardware acceleration via
window.crypto.subtle. - Zero Analytics & Telemetry: No tracking cookies, Google Analytics, or third-party monitoring scripts are embedded.
- Open Source Integrity: You can inspect the network tab in your browser's DevTools (F12) to verify that zero outgoing network calls are made while decoding or verifying your tokens.
