JwtCity

Jwt City is a cyberpunk-styled toolkit for developers and technical users.
Inspect links and payloads, decode JWTs, clean UTM, trace redirects, build text pipelines, test deep links, and visualize data with Hex Radar—fast and focused. J Lab — Smart Inspector
 • Paste URL, JWT, Base64, Hex, or JSON for instant parsing and pretty output.
 • Switch between Readable and Raw views.
 • One-tap actions to send input to other tools. JWT Inspector
 • Decode header/payload; see alg, kid, exp/iat/nbf at a glance.
 • Optional signature verification with your key/cert (HMAC/RSA/EC).
 • Clear status for expiration and validity. UTM Clean
• Remove UTM, fbclid, gclid, mc_eid, and other trackers.
 • Compare original vs. cleaned URL with a quick diff and stats. Redirect Trace
 • Safely follow redirects (HEAD/GET) with a hop limit.
 • Each step shows status code, protocol/HTTPS, timing, and key headers.
 • Export a detailed text report and try built-in test URLs. Deep Link Playground
 • Edit scheme/host/path and query parameters.
 • Local preview for universal link patterns. J Macros — Text Pipelines
 • Build reusable chains: Regex Replace, URL/Base64 Encode/Decode, JSON Pretty, UTM Clean, Slugify, Trim, Case, Split/Join.
 • Live two-pane diff as each block applies.
 • Save presets and share via QR. Hex Radar
 • Hex-grid visualization and XOR heatmap for differences.
 • Pinch to adjust row width (8/16/32 bytes).
