Stack Architecture & Privacy FAQs
Are my proprietary JSON payloads or API endpoints safe on these tools?
Yes. Tools like JSON Crack and Regex101 process your input strictly within the browser DOM and WebAssembly memory. They do not persist or transmit data to remote servers.
Can DevDocs be used when on an airplane or offline?
Yes. DevDocs utilizes browser IndexedDB and Service Workers to cache entire documentation libraries locally for fast offline access.
