Paste or drop application logs and read them as a clean, structured list. Detects logfmt, JSON lines and common plain-text formats, colors levels and timestamps, and lets you expand or collapse the fields of every entry.
Runs entirely in your browser. Nothing you put in here gets uploaded.
This tool turns raw log output into a readable, structured list. Paste log lines or drop a log file and every line becomes an entry with a colored level badge, a timestamp, the message and its remaining fields. The format of each line is detected automatically, so logs that mix logfmt, JSON lines, klog and syslog output still parse correctly, and a manual override forces one parser when detection guesses wrong.
The list is built for reading through a problem: hide the noise with per-level filters, search across all entries, expand a single entry or all of them to see the structured fields, and copy any entry's original line for a bug report. Timestamps show as written or as relative times like 5 minutes ago.
Detection runs per line, so a file that mixes formats still works. JSON entries take their level, message and timestamp from the usual keys (level, msg, time, @timestamp and friends) and understand pino's numeric levels. Logfmt lines handle quoted values and escapes, and free text between pairs becomes the message. klog lines decode the leading I, W, E or F letter plus the source location and pid. Syslog lines work with or without a priority prefix, whose severity is used when present. Everything else falls back to plain text, where a leading ISO timestamp and a level keyword like ERROR: are still picked out.
Parsing is capped at 50,000 lines and the list renders in batches of 500 with a count of what is hidden, so a big log stays scrollable instead of freezing the page. The level filter and search always run over every parsed entry, not just the visible batch.
A log you paste into a ticket often carries addresses, tokens or user data. Send the loaded log to the Log Redactor to strip sensitive values first. For digging into one large JSON entry, the JSON Inspector shows it as a collapsible tree.
