About

DevKnife is a lightweight all-in-one toolkit for developers on macOS. It brings together common utilities in a single native app, so you don’t have to switch between websites, CLI tools, or bulky IDEs for simple tasks. Current modules include: JSON Editor & Formatter, Text Compare, JWT Decoder, Domain & IP WHOIS, Port Scanner, Network Speed Test, Color Picker, Hasher, and IP Location. All tools are built to run locally without relying on third-party APIs. For network-related features like WHOIS or Speed Test, DevKnife connects directly to the relevant servers without sending your data elsewhere. DevKnife is actively developed with new features and modules added over time — a handy companion for everyday developer tasks.
