The dev tools you've always wanted. Decode JWTs, manage secrets, compare files, format JSON, inspect databases everything runs locally. No accounts, no tracking. Developers Kit is a native macOS app housing eight focused developer utilities, all running 100% locally with zero cloud dependencies. Shipped Tools: • JWT Inspector — Decode and verify JWT tokens. Inspect headers, claims tables, interactive JSON trees, and validate HS256 signatures against your secret. • Password Manager — Local 1Password-style vault with AES-256-GCM encryption, PBKDF2 key derivation (650K iterations), TOTP generator, breach detection (HIBP k-anonymity), password strength analyzer, and auto-lock. Master password protects everything—no secret key needed. • ENV Manager — Create and manage environment profiles locally. Values encrypted in macOS Keychain, revealed only after Touch ID or password auth. Export .env files securely. • Clipboard Manager — Supaste-style clipboard history. Instant access to your last 500 clips, organized by type (text, links, code, images, colors). Sensitive heuristics flag potential secrets—never stored or transmitted. • Database Client — Connect to PostgreSQL, MySQL, SQLite, Redis, MongoDB, or DynamoDB. Schema browser, SQL editor with tree-sitter syntax highlighting, data grid with inline editing, deferred commits (review before executing), import/export (CSV/JSON/SQL/XLSX), 6-level safe mode for production databases, SSH tunneling support. • JSON Formatter — Format, minify, validate, and sort JSON locally. Interactive tree inspector with copy, search, and prettify controls. • Diff Tool — Compare text with line-by-line diffs. Split and unified views, syntax highlighting. • Port Manager — List all locally listening TCP ports with owning process names and PIDs. Quickly identify port conflicts in your dev environment. Privacy & Security: Everything runs on your Mac. No analytics, no telemetry, no network calls except explicit database connections you initiate. Passwords and secrets live in macOS Keychain (Touch ID or password protected). App is fully sandboxed on Mac App Store—no file system access beyond what you explicitly grant. Perfect for developers who want powerful, focused tools without the bloat, complexity, or privacy concerns of cloud-based alternatives. Free to download — every tool included. Requires macOS 26.5 or later.
