Logbeam od Dre

Logbeam makes raw logs readable and keeps everyday developer tools one right-click away.

LOG VIEWER (Alt+Shift+L)
• ERROR / WARN / INFO / DEBUG / TRACE in colour, with counters and one-click filters
• Java, Python and Go stack traces stay grouped with their error
• Plain-text and regex search with highlighted matches
• JSON logs (Logstash, pino, bunyan, zap) shown as readable lines
• Pauses between entries (+30.0s) show where the app stalled
• Collapse repeated lines: 500 identical retries become one line with ×500
• Jump to the next error, copy the visible lines
• Fast on 100,000+ lines

DARK MODE FOR ANY SITE (Alt+Shift+D)
• Turn it on for the current tab, or remember it for a site
• Photos and videos keep their real colours

TEXT TOOLS: select text, right-click, then Logbeam
• Format / minify JSON
• Decode JWT with expiry status
• Base64 and URL encode / decode
• Unix timestamp ⇄ date
• Explain cron expressions (Unix and Spring)
• camelCase / snake_case / kebab-case / CONSTANT_CASE
• Sort and de-duplicate lines
• "Replace selection" writes the result back into inputs and editors
