Dev Workbench

Dev Workbench is a native macOS app that brings 16 developer utilities together for everyday debugging, data inspection, and development workflows — without constantly switching between browser-based tools. Go beyond simple converters: analyze CSV and JSON files locally using SQL (DuckDB backed), inspect structured logs with filtering and charts, format and query JSON with jq, and inspect or generate JWTs. It also includes Unix timestamp conversion with customizable time zones, cron schedule simulation, regex testing, text diffing, cURL-to-code conversion, URL inspection, IP/CIDR calculations, encoding and decoding tools, color utilities, and more. Most processing runs locally on your Mac, with no ads, tracking, analytics, or account requirement. Core utilities are free. Dev Workbench Pro is available as a one-time purchase for higher limits and advanced capabilities. Requires macOS 14 or later.
