Browse and search JSON safely. Tree view, JSON Pointer paths, key-value search — all running in your browser, none of it uploaded.

Runs entirely in your browser — no upload, no wait.
Your JSON never leaves the tab. Nothing is logged.
Free, unlimited, no account required.
Sometimes you need to read JSON, not edit it. A tree viewer with collapsible nodes, breadcrumb paths, and search is faster for that than a flat code editor — especially for deeply nested API responses.
Mask values matching common secret patterns (Bearer tokens, AWS keys, JWT) with one click. Redact specific paths before exporting screenshots. Copy the JSON Pointer to any node so you can reference it without copying the value.
Full-text search highlights matching keys and values. JSONPath queries (e.g. $..users[?(@.active==true)]) return only the matching subtrees. Both operate on the in-memory tree, not the source text.
# Example pointer
/data/users/0/email
# Example JSONPath
$.data.users[?(@.role == 'admin')]All viewing, searching, and masking happens in your browser. The JSON is never uploaded. Even masked exports are generated locally.
Trees are virtualized — 100k+ node documents stay smooth. Searches debounce automatically so typing in a long query stays responsive.
