A browser-only toolkit for formatting, converting, comparing, and inspecting JSON without uploading the data.

Landing page captured for the 2026-08-29 issue.

Field notes

The live portion is organized around JSON work: formatting, minifying, schema and language conversion, diffing, JSONPath testing, and secret or PII scanning. LocalUse says each page is a pure browser function and ships with `connect-src 'none'`, while its deployment process reportedly tests fetch, XHR, WebSocket, beacon, remote modules, and image-pixel exfiltration. CSV, regex, PDF, image, encoding, and JWT sections are identified as forthcoming or curated rather than fully built.
