About this app

DevToolbox – Ultimate Developer Companion & Utility Suite
​DevToolbox is an all-in-one pocket workspace designed for software engineers, backend developers, mobile app creators, DevOps professionals, and coding students. Boost your daily workflow and developer velocity without relying on heavy desktop setups or constant internet connectivity.
​Whether you are commuting, traveling, or working offline, testing APIs, formatting code, drafting ideas, and generating CLI commands on the go.
​🚀 Key Features & Detailed Utilities:
​📁 1. Offline Code Editor (GitHub-Style Repository Workspace)
​Features: Create projects just like GitHub repositories with nested folders and multi-language files (index.html, style.css, script.js, app.py, main.kt, README.md, etc.). Features line numbers and a dedicated developer symbol bar ({ } [ ] ( ) ; : " ' = < > / \ $ _ - + * -> tab).
​Edit, inspect, and draft scripts anywhere directly from your phone. Zero lag, no account required, and completely offline with local persistent storage.
​📡 2. Live HTTPS API Tester (Pocket Postman Client)
​Features: Send HTTPS requests (GET, POST, PUT, DELETE, PATCH) directly from your device. Add custom headers, construct JSON payloads, inspect status code badges, measure round-trip latency (ms), and export instant 1-tap cURL commands.
​Quickly test server endpoints, microservices, or webhook availability without booting up your laptop.
​3. Interactive Git Command Generator
​Features: Dynamic command builder for cloning repositories, creating/switching branches (git switch -c), rebasing, unstaging changes, soft/hard resets, and undoing last commits.
​Customize branch names or remote URLs with real-time preview, copy instantly, and run with confidence.
​📋 4. JSON Formatter, Validator & Minifier
​Features: Beautifully format unorganized JSON payloads with 2-space or 4-space indentation, minify for production payloads, and detect syntax errors with real-time error messages and key/item counters.
​Effortlessly debug messy backend responses, inspect config files, and validate API schemas directly on your screen.
​🔐 5. Crypto: Base64 & Hash Generator
​Features: Encode and decode plain text to Base64 (with URL-safe mode support) and instantly compute cryptographic hashes including MD5, SHA-1, SHA-256, and SHA-512.
​Essential for token validation, secret verification, hashing passwords, and inspecting encoded web parameters in seconds.
​📝 6. Notes & Snippets Vault (Local Room Database)
​Features: Save vital code snippets, queries, and architectural ideas organized by tags (#Git, #API, #Docker, #Snippet, #Idea). Pin critical notes and search through your repository anytime.
​Never lose a command or quick workaround again. Fully persistent offline storage keeps your personal snippet library safe on your device.
​🔍 7. Regular Expression (Regex) Playground
​Features: Real-time regex matching with visual match highlights, flag controls (i, m, s), substitution (find & replace), and ready-to-use presets (Email, URL, IPv4, Phone, Hex Color, Date).
​Test validation rules and extract string patterns without switching between browser tabs.
​8. Docker & ngrok Command Builder
​Features: Interactive container run command generator (port mapping, container naming, detached mode, environment variables) alongside ngrok tunnel utilities and troubleshooting cheat sheets.
​Build clean Docker CLI scripts and expose localhost services (ngrok http 8080) effortlessly.
​📚 9. Curated IDE Shortcuts & Developer Guides
​Features: Comprehensive shortcut maps and CLI productivity tips for Visual Studio Code, IntelliJ IDEA, and Android Studio.
​Master your desktop IDE workflows and discover
​Coding Students & Beginners: Understand Git workflows, test APIs, learn regular expressions, and explore IDE shortcuts interactively.
​DevOps & QA Testers: Test REST APIs, generate network commands, and verify payload encodings instantly.
