Description

Beautiful, 100% local JSON viewer with tree, search, diff, JWT decode & JSONPath. No tracking. Open any JSON in your browser and DevJSON turns it into a clean, interactive view — instantly. Built for developers who live in APIs, and built to be 100% local, with no network calls and no tracking. Most "JSON viewer" extensions are a privacy minefield — several have shipped ads or trackers. DevJSON does the opposite: everything happens in your browser, nothing is ever sent anywhere. FEATURES • Automatic, beautiful tree view for any application/json page • Search, collapse/expand, and one-click copy • JSON diff — compare two payloads and see what changed (Pro) • JWT decode — inspect header & payload locally (Pro) • JSONPath queries — pull values out of big objects fast (Pro) • Format / minify scratchpad for pasting JSON • Light & dark themes PRIVACY FIRST 100% local. No network requests, no analytics, no tracking — your data never leaves the browser. FREE & PRO Free includes the tree viewer, search, and format/minify. Pro unlocks diff, JWT decode, JSONPath, and saved snippets. Built by ForgeWorks.
