New tools added in v1
JWT Inspector

Decode header and payload locally, surface issuer, audience, expiry, and suspicious structure fast.

PEM Block Parser

Identify certificate, CSR, private key, or chain blocks and summarize what is inside without leaving the browser.

HTTP Header Parser

Paste raw request or response headers and turn them into structured fields you can scan or reuse.

Small Business QR Kit

Pick a template → fill one field → generate. Use Batch to produce multiple codes (WiFi, call, meeting, links) in one pass. Everything is client-side.

Guest WiFi
Scan to join WiFi. Uses proper WiFi QR escaping (fixes “SSID adds but password fails”).
WIFI
Scan to Call
Create tel: QR codes for front desk, service, reservations.
TEL
Scan to Email
Create mailto: QR for support or bookings with subject/body.
MAIL
Scan to Review
Paste your Google review link (or any review URL). Great for receipts/signage.
REVIEW
Scan to Meeting
Link to Calendly, Microsoft Bookings, Google Appointment Schedule, etc.
MEET
Scan to SMS
Create sms: for “text us” flows.
SMS
vCard Contact
Creates a vCard for staff/business contact saving.
VCARD
Input is fields only; we wrap into a valid vCard automatically.
Batch Generator
One line per QR. Format: label | type | value. Types: url, tel, sms, mailto, wifi, text.
WiFi QR Code Generator (Fixed)
Uses WiFi QR escape rules (backslash escaping) for better real-world scan success.
If your password contains ; , : \ or quotes, escaping is handled automatically.
Standard QR Code Generator
Tip: Use High ECC for posters/menus and when people scan from a distance.

Advanced utility rack

Use the search and category chips to cut through the full tool grid. This keeps the workspace dense without forcing you to visually scan every card each time.
