RawLens

Inspect raw JSON, ANSI logs, YAML, HTML, JS, CSS, and source-like text directly in Chrome.

RawLens helps developers inspect raw browser content without leaving Chrome. It turns unreadable pages, copied logs, API responses, CI output, selected DOM text, and page source into highlighted, formatted views. It is especially useful for raw JSON error payloads, ANSI-colored terminal output, YAML/config files, HTML, JavaScript, CSS, Markdown, SQL, diffs, patches, and XML. Highlights: - Pretty-print raw JSON, including stack traces, escaped newlines, and nested JSON strings. - Render ANSI terminal colors from CI logs, build logs, and copied command output. - Auto-format source-like files opened directly in Chrome. - Inspect selected text, hovered DOM nodes, clipboard content, page source, or page HTML. - Reopen recent views from a local History panel. - Use quick shortcuts: vv, pp, cc, hh, xx, ff, and Esc. - Works locally in your browser. No server, no tracking, no log collection. Common use cases: - Reading API JSON responses. - Inspecting raw GitHub/GitLab CI logs. - Viewing copied production error logs. - Opening YAML, JSON, JavaScript, CSS, Markdown, SQL, patch, and diff files. - Formatting logs from a selected page element or clipboard.
