DevToolChain packs the developer tools you reach for daily — JSON, JWT, hashing, encryption, diff, QR code generator — into one fast, fully offline app. Every developer tool you reach for, in one native app. Nothing leaves your Mac or iPhone. DevToolChain is a fast, native toolbox for developers — built entirely on Apple frameworks, with zero third-party dependencies and zero network calls. Paste a token, hash a string, or decrypt a payload knowing none of it touches a server. No accounts, no analytics, no ads. Stop pasting secrets into random websites. FORMATTERS & TEXT - JSON — validate, pretty-print, and minify with syntax highlighting - Regex — test patterns live and inspect every capture group - String Toolkit — change case, trim, sort, count, and escape - Diff Checker — compare two texts line by line ENCODING - Base64 — encode and decode, standard or URL-safe - URL Encode — percent-encode and decode - QR Code — generate QR codes from any text, with selectable error-correction levels. Copy or share the result as an image. HASHING & TOKENS - Hashing — MD5, SHA-1, SHA-256, SHA-512 - HMAC — keyed message authentication - JWT — decode, verify, and sign JSON Web Tokens CRYPTOGRAPHY - AES — AES-GCM encrypt and decrypt - Asymmetric Keys — generate keypairs, sign, verify, and RSA encrypt SECRETS - Keychain — store secrets in the system Keychain, each guarded by your choice of no lock, device passcode, or Face ID / Touch ID. Values are only decrypted when you explicitly reveal them. NETWORK (macOS) - Network Scanner — discover hosts and open ports on your local network, with hostname and service resolution BUILT THE RIGHT WAY - Native SwiftUI on both macOS and iOS — one purchase, both platforms - No third-party dependencies. No telemetry. No sign-in. - Everything runs on-device - Fully localized in English, German, Spanish, French, and Turkish - Searchable sidebar — find any tool by name or by what it does
