An editor-style JSON viewer with structure tree, search, and themes. Bonsai turns raw JSON responses into a fast, read-only, editor-style viewer: the experience of opening the file in a desktop code editor, directly in the tab. • Structure panel: a virtualized tree of the document with type icons, counts, copy-value / copy-path (JSONPath, dot, bracket) on every row, and reveal-in-structure from any editor line. • Editor niceties: code folding by level, breadcrumb path bar, hover row actions, precise error markers with clickable line:column for malformed documents. • Full-document search: case / whole-word / regex, match count, auto-unfolds folded matches • Automatic takeover of JSON pages (correct Content-Type + JSON-looking body), with a one-click "View raw document" escape hatch and a manual "Format this page" override from the toolbar popup. • Handles large documents (tiered rendering up to tens of MB) •and local files (works on file:// JSON/JSONL once you enable "Allow access to file URLs"). • JSON, JSONC, and JSON Lines / NDJSON (multi-record streams fold into an array view with a record-count badge). • Keyboard-first navigation: arrow keys move between rows, collapse a node, or expand it (the same behavior in the editor and the structure tree). Ctrl/Cmd+Enter to reveal the cursor's node in the structure tree, Ctrl/Cmd+F to search the whole document, Ctrl/Cmd+A and Ctrl/Cmd+C to select and copy the full document, F3/Ctrl+G to step through matches. • Dark & light themes with live switching, bundled fonts, settings sync across your Chrome profiles. See it in action: https://daaar.github.io/bonsai-extension/examples Privacy: everything runs locally in your browser. Bonsai never transmits page content or any other data anywhere. The only thing it stores is your own settings (theme, layout) in Chrome's sync storage.
