As answered by people managing DevArmory.org and devtoolz.dev.
DevArmory.org's answer
DevArmory is 100% client-side and offline-first. All parsing, code diffing, formatting, and JWT decoding execute purely in local browser memory using modern Web APIs. No user data, proprietary code, or API tokens are ever transmitted to or stored on a remote server.
DevArmory.org's answer
Unlike bloated, ad-cluttered online formatters that upload code to unknown servers or charge recurring subscriptions, DevArmory is completely free, lightning-fast, and privacy-first. It includes a built-in ⌘K command palette, PWA offline capability, and client-side team sharing links.
DevArmory.org's answer
Software engineers, web developers, DevOps professionals, QA testers, and digital creators who need fast, daily utilities without security or compliance risks.
DevArmory.org's answer
DevArmory was built out of frustration with sketchy online formatters that log user payloads to remote backends. When dealing with customer PII, internal SQL queries, and API authorization tokens, sending code to third parties is a major security hazard. DevArmory was created to give engineers an everyday armory that guarantees complete client-side privacy.
DevArmory.org's answer
HTML5, Modern CSS3, Vanilla JavaScript (ES6+), Web Workers, Service Workers (PWA), and native browser Web APIs (crypto.subtle, Canvas, LocalStorage).
