CodeBox

CodeBox is a private developer toolbox built for quick work on Android. Paste or share text into the app and Smart Detect ranks the formats it recognizes, then opens the most relevant utility with your content ready to use.

Everything is processed on your device. CodeBox does not require an account, upload your tool input, or depend on a cloud service for conversions.

SMART DETECT
Recognize URLs, JSON, Unix timestamps, colors, Base64, UUIDs, and JWTs with confidence-ranked suggestions.

DEVELOPER UTILITIES
• Format and validate JSON
• Convert Unix timestamps to local, UTC, ISO 8601, and relative time
• Encode and decode Base64 and URL text
• Convert HEX colors to RGB and HSL
• Generate cryptographically secure passwords and UUIDs
• Calculate SHA-256, SHA-512, and MD5 hashes
• Inspect URL hosts, paths, parameters, and common structural risks
• Decode JWT headers and claims

BUILT FOR MOBILE WORK
Send text to CodeBox from the Android share sheet, copy results in one tap, and keep frequently used tools close with favorites and recents.

SECURITY NOTES
URL inspection is a structural check, not a malware scan. JWT signatures are not verified. MD5 is included only for compatibility with existing systems.
