Portable Log Viewer

The feature-rich viewer for log files from Microsoft, Omnissa, and others — with your own notes notes, live tail, and more!

The feature-rich viewer for log files from Microsoft, Omnissa, and others — with your own notes, live tail, and more! 🔍 Stop scrolling through walls of text to find the one line that matters. Portable Log Viewer turns raw Microsoft, Omnissa, and other vendor logs into something you can actually read — color-coded by severity, sortable and searchable column by column, and live-tailing as new lines are written. 🔒 PRIVATE BY DESIGN Your log files are read locally in your browser and are never uploaded. There is no account, no analytics and no tracking, and the developer receives none of your data. The one optional exception is the AI summary, described below, which only runs when you click it. 📋 BUILT FOR THE LOGS IT ACTUALLY DEALS WITH Auto-detects Microsoft log entries (CMTrace / ConfigMgr), Windows Installer verbose logs (MSI), and every flavor of Omnissa log (Hub, HubApi, Provisioning Tool) — or falls back to smart keyword detection for anything else. Pipe-delimited fields get broken into their own sortable columns automatically, so structured data stays structured. 🎨 MARK IT UP WITHOUT TOUCHING THE ORIGINAL FILE Click any entry to add a note and tag it with a color — right there in the browser, never written back to the log. Sort or filter the whole table by note color to instantly surface everything you flagged as critical. Notes are saved on your device. 📤 SHARE YOUR FINDINGS TWO WAYS Export exactly what's on screen as a spreadsheet-ready CSV, or as a plain-text Annotated Log that anyone can read in a text editor — no extension required. Reopen your own annotated export later and your notes and colors come right back automatically. 🤖 OPTIONAL: SEE ROOT CAUSES FASTER WITH AI One click sends the currently visible entries (up to the most recent 300) to an AI provider you choose for a plain-English summary: errors grouped by likely cause, patterns flagged, next steps suggested. Filter first to send only what you want analyzed — log entries can contain hostnames, usernames and paths. 🔑 REQUIRES YOUR OWN API KEY This extension does not include, resell, or bundle any AI service — you bring your own key from Claude, ChatGPT, or Gemini's developer console. Requests go directly from your browser to that provider (Anthropic, OpenAI, or Google) and nowhere else; they do not pass through any server operated by the developer. Your key is stored on your device. There is no separate sign-up or subscription through this extension, and the provider's own terms and privacy policy apply to what you send. 🪟 KEEPS WORKING WHEN YOU SWITCH TABS Pop the viewer out into its own standalone window or a normal browser tab and tailing keeps running in the background. 🌗 LOOKS RIGHT, DAY OR NIGHT Light, dark, or match-your-system theming, switching live if your OS theme changes while the extension is open. ☁️ PORTABLE — INSTALLS ITSELF ON ANY COMPUTER YOU USE Stuck on a machine that isn't yours with a log you need to read and no viewer in sight? Sign in to Chrome and Portable Log Viewer is installed there too through your Chrome profile — no hunting for a tool when you're already elbow-deep in someone else's system. Your notes, settings and API key stay on each device and are not synced between computers. ✅ EVERYTHING ELSE YOU'D EXPECT Draggable, resizable, show/hide columns • full-text find with next/previous • per-column filters • numeric and chronological sorting that understands each format's date layout • a detail pane with the complete original entry • 8,000-row live view that stays fast on long-running logs. Whether you're chasing down a failed SCCM deployment, a broken MSI install, or an issue in Workspace ONE — Portable Log Viewer gets you to the answer faster, and helps you show your work to whoever's reviewing it with you.
