Logbeam

Readable logs, dark mode for any site, and one-click JSON / JWT / Base64 / timestamp / cron tools. 100% local.

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 PRIVACY Everything runs locally in your browser. Logbeam has no server and no analytics, and it sends no network requests. Open source: https://github.com/andronaft/Logbeam
