support@fallingdata.zoneOpen any log file by dragging it onto the Timber window or dock icon, or use File > Open. Timber auto-detects JSON Lines, logfmt, syslog, Apache, and plain text formats. No configuration needed.
Timber auto-detects and parses JSON Lines (.jsonl), logfmt, syslog (RFC 3164 & 5424), Apache/nginx combined format, and plain text. It also opens iOS/macOS crash reports (.ips and .crash) and gzip-compressed files (.gz).
Timber uses memory-mapped I/O and can handle files up to 2 GB. For very large files, it uses virtual scrolling so only visible rows are rendered.
Yes. Click the .* button in the toolbar to enable regex mode. Your search text will be interpreted as a regular expression.
Timber loads your log data into an in-memory SQLite database. Open the SQL panel to write queries like SELECT * FROM log_lines WHERE level = 'error' AND message LIKE '%timeout%'. Press Cmd+Enter to execute. Results can be exported to CSV or JSON.
Yes. Press Cmd+T or click the Tail button in the toolbar. Timber uses kqueue for low-latency file change detection and will auto-scroll to new entries as they arrive.
Open a .ips crash report and Timber will automatically search for matching dSYM files via Spotlight. You can also drag dSYM files onto the crash view or browse for them manually. Symbolication resolves memory addresses to function names, file paths, and line numbers.
No. Timber works entirely offline. All parsing, searching, and analysis happens on your Mac. No data ever leaves your device.
Timber includes a 14-day free trial with full functionality. After the trial, you can purchase a one-time license to continue using the app. No subscription required.
Yes. Open 2–6 log files in separate tabs, then press Cmd+Shift+M to merge them into a unified chronological timeline. Each source file is color-coded for easy identification.
Yes. Timber supports the timber:// URL scheme. For example, timber://open?path=/var/log/system.log&tail=true opens a file and starts tailing it. This enables integration with scripts, Alfred workflows, and AI agents.
