About
You can run it against any web page, be it public or require authentication. It has audits of performance, accessibility, progressive web apps, SEO and more. You can run Lighthouse in Chrome Devtools, from the command line, or as a Node. You simply give Lighthouse a URL to audit, it will run a series of audits against the page, and then generate a report on how good the page was. From there, use the audits that have failed as pointers on how to improvise the page. Each audit has a reference doc explaining why the audit is important, as well as how to fix it. Lighthouse Viewer requires the JSON output of a Lighthouse report. The following list explains how to get the output in JSON format depending on which Lighthouse stream you are using.

About
SafeJSON is an all-in-one local JSON toolkit built exclusively for developers. All parsing, comparison, JWT decoding and validation runs 100% inside your browser, with zero user data uploaded to external servers.
Core features include standard JSON formatter, visual JSON Diff, JWT token decoder, JSONPath query engine, and JSON Schema validator. It supports huge 50MB+ JSON files powered by Web Workers, dark mode, collapsible tree views, and one-click raw JSON export.
Users can independently verify full privacy via Chrome DevTools Network panel — no API keys, tokens or confidential payloads leave your device. The core toolset is permanently free, with advanced features (Diff & JWT) available via SafeJSON Pro ($5/month or $39/year). The full codebase is fully open-source on GitHub for full audit.
