What is Logpad

Logpad is a lightweight desktop editor for logs and plain text, available on Windows and Ubuntu. It supports large files, multiple encodings and tabs, with a small footprint that suits keeping it running on a laptop.

Unlike an ordinary notepad, Logpad supports saved search templates and log TAG rules: templates store frequently used keywords for instant reuse, while TAG rules mark key log lines and can filter search results down to matching lines only. Both can be kept on your machine with no login required, or uploaded to the cloud — sign in with the same account on another Windows / Ubuntu device and all your templates and TAG rules sync automatically.

Logpad is built for log triage with an “open, search, jump” flow: search every opened file at once, see results grouped by file, and double-click an entry to jump straight to its line. Filter results by time window, requestId / traceId or log level, and hop quickly between WARN, ERROR and other exception levels.

你可以用它做什么

Multi-file batch search: search all opened files at once; results grouped by file, double-click jumps to the target line.
Narrow logs by request trail: use time windows and requestId / traceId to pull one complete call chain out of massive logs.
Log level highlighting & quick jumps: WARN and ERROR lines are auto-colored — no more manual line-by-line scanning.
Markdown editing & preview: edit .md source directly and toggle a preview to see rendered headings, lists and links.
Search templates: save frequent queries like “Exception” or “timeout” and fill the search box in one click; store locally or sync across devices via the cloud.
Custom TAG rules: color your own keywords and show only matching lines in results; keep rules local or sync them with your account.
Two-file compare: put two opened files side by side to diff logs before/after a release or across servers.

Logpad is made for backend developers, ops and technical support teams — a capable replacement for the classic notepad way of reading logs. It keeps notepad’s simple open / edit / save habits while upgrading search, analysis and comparison. It ships with Chinese and English UIs plus light and dark themes, so it looks comfortable and fits any preference.
