JSON Bonsai sɣur hackslashdash

JSON Bonsai turns any raw JSON page into a fast, interactive viewer — built to stay smooth on payloads with 100,000+ nodes.

Open any URL that returns JSON and JSON Bonsai automatically replaces the wall of text with a clean, navigable tree. Then prune it, search it, query it, or reshape it — without the browser grinding to a halt.

Five ways to look at your data
- Tree — virtualized rendering that scrolls smoothly even on huge payloads, with collapsible nodes and depth controls
- Table — sortable, virtualized rows for arrays of objects (works on query results too)
- Formatted — clean, pretty-printed JSON
- Raw — the original response, untouched
- Schema — an inferred JSON Schema (draft-07) of your data

Find and reshape anything
- JMESPath query bar with autocomplete and history — filter and reshape the JSON; the result renders as a fully interactive tree
- Content search with regex mode, run in a background worker, with match-to-match navigation
- Hover any property to see its full JSON path; click to pin and copy
- Copy any subtree, or copy exactly what the active view shows

Gets the details right
- Lossless big numbers — 64-bit IDs and high-precision decimals display and copy exactly as sent, where the browser's own parser would silently corrupt them
- Syntax highlighting for keys, strings, numbers, booleans, and null; URLs become clickable links

Made to feel like yours
- base16 theming — 13 bundled color schemes plus your own custom themes, with auto / dark / light switching
- Per-site memory — your view mode and tree depth are remembered per origin and restored on your next visit
- Keyboard-driven — 1–8 set tree depth, 0 expands all, Q queries, ⌘F searches, C copies

Works in both Chrome and Firefox.
