DevWorkbench: Offline DevTools

Apps ViT Limited

About this app

Never paste internal company secrets, tokens, or logs into untrusted online websites again.

DevWorkbench is a 100% offline, privacy-first developer sandbox designed for software engineers, DevOps specialists, and security teams. Format JSON, decode JWTs, inspect Unix timestamps, and sanitize sensitive credentials in an air-gapped environment right on your device.

🔒 ZERO NETWORK PERMISSIONS — 100% AIR-GAPPED
Unlike random web-based formatters and decoders that transmit your logs to remote servers, DevWorkbench requires ZERO internet permissions (no android.permission.INTERNET).

• No external servers
• No tracking, telemetry, or analytics
• No ads or third-party cookies
• Works 100% in Airplane Mode / without Wi-Fi
• Zero bytes ever leave your device memory

⚡ 4 ESSENTIAL DEVELOPER UTILITIES
━━━━━━━━━━━━━━━━━━━━━━━━━━━

1. THE SECRET SCRUBBER (Mask & Sanitize Credentials)
Safely sanitize .env files, server logs, shell outputs, and database dumps before sharing them on Slack, GitHub Issues, Jira, or StackOverflow.
• Auto-detects: OpenAI (sk-...), Anthropic Claude, AWS Access Keys (AKIA...), Stripe Keys (sk_live...), GitHub Tokens (ghp_...), Database connection passwords (postgres://...), Bearer headers, and customer PII (emails & IPs).
• 3 Masking Modes:
- Bullets (••••••••): Preserves prefix context (e.g. sk-proj-••••••••8374)
- Semantic Tags ([MASK]): Clean labels (e.g. [SCRUBBED_API_KEY])
- Delete: Completely removes the sensitive segment
• 1-Tap Copy: Instantly copy sanitized logs ready for sharing.

2. UNIVERSAL LOCAL JSON INSPECTOR & FORMATTER
• Instant Parsing: Prettify, inspect, and minify JSON in under 2 milliseconds.
• Syntax Validation: Real-time error detection showing precise line errors.
• 100% On-Device: No cloud parsers or external APIs.

3. OFFLINE JWT & UNIX TIMESTAMP DECODER
• Base64URL JWT Decoder: Inspect Header and Payload claims offline.
• Expiration Checking: Calculates whether tokens are valid or expired against your local system clock.
• Unix Epoch Converter: Convert epoch seconds and milliseconds to both Local Time and UTC, complete with a quick "Now" timestamp generator.

4. REAL-TIME AIR-GAP VERIFICATION
• Built-in network isolation indicator showing:
"● Air-Gapped Mode: 0 Requests Sent | 0 Bytes Leaked"
• Gives developers and compliance teams total peace of mind.

🛡️ COMPLIANCE & DEVELOPER SAFETY
━━━━━━━━━━━━━━━━━━━━━━━━━━━
Pasting corporate data into random web formatters can violate GDPR, HIPAA, SOC 2, and internal corporate confidentiality policies. DevWorkbench gives you the speed of modern developer utilities with the security of a closed local sandbox.

Whether you're debugging microservices, checking authentication tokens, or cleaning up logs for a bug report, DevWorkbench is your daily, trusted companion.

Download DevWorkbench today and keep your code, keys, and tokens secure!
