About this app
TechToolbox brings together, in a single native app, all the tools developers, system administrators and network administrators need on a daily basis — usable entirely offline, with no account and no connection required, except for one clearly identified category of network tools.
JSON/XML formatting, JWT decoding, test data generators, subnet calculations (CIDR), a crontab and HTTP error code cheat sheet, encryption and hashing, a snippet manager, and much more: 40+ tools organized by category (Development, Network, System Administration, Security, Productivity), available in seconds, even without a network connection.
Full list of tools, by category:
Development: UUID generator, Lorem Ipsum generator, Password/token generator, Text case converter, Number base converter, Color picker and converter, Base64, URL encoder/decoder, Hash generator, JWT decoder, Unix timestamp converter, Cron expression parser/explainer, JSON, XML, YAML formatter/validator, Markdown previewer, Git/Docker/HTTP cheatsheet, QR code generator/scanner, Advanced regex tester, Advanced diff comparator.
Network: Subnet / CIDR / VLSM calculator, Network unit converter, Well-known ports reference, Imported SSL certificate viewer, MAC address reader/analyzer.
System Administration: Crontab generator, Storage and time unit converter, Advanced log viewer, Config snippet generator, Uptime / SLA calculator, Windows/Sysmon error code database, Linux man pages.
Security: Password strength checker, AES encryption/decryption, Hash comparator.
Productivity: Snippet manager, Quick technical notepad.
Online Tools: TCP connection test, Ping, Whois, DNS lookup, Reverse DNS lookup (PTR), SPF/DKIM/DMARC checker, TLS/handshake test, Remote certificate viewer, HTTP headers inspector, HTTP request tester, My public IP.
An "Online Tools" category (ping, DNS, TLS, HTTP headers, public IP…) is clearly identified with a badge and only ever contacts the host you explicitly enter — never a server operated by the publisher.
Privacy by design: no third-party telemetry, no advertising SDK, no data sent to a proprietary server. Anything you enter into an offline tool stays on your device.
Free with a complete base set of tools; a one-time Pro unlock (no subscription) gives access to the full set of advanced tools.
