Google Calendar Chrome Extension — Events in Your Side Panel

What It Does

OneBuddy integrates with Google Calendar through secure OAuth 2.0 authentication, bringing your schedule directly into the Chrome side panel. View today's and upcoming events at a glance without opening a new tab or switching windows. Chrome alarm-based notifications alert you before meetings so you never miss an appointment, even when you're deep in a work session. The calendar view updates periodically to keep your event list current, and it uses Google's official OAuth flow so your credentials are never stored by OneBuddy. Your calendar sits alongside your Pomodoro timer, notes, and habits for a complete productivity command center.

Why It's Better Than Standalone Extensions

Dedicated Google Calendar extensions like Checker Plus or Google Calendar by Google only show your schedule and add yet another extension to your browser. OneBuddy shows your calendar alongside your Pomodoro timer, notes, habits, clipboard manager, and 10+ other tools — creating a complete productivity command center in a single Chrome side panel. By consolidating your calendar viewer with other daily-use tools, you reduce your extension count, save browser memory, and declutter your toolbar. The secure OAuth 2.0 integration means your data stays safe, and everything is free with no premium tiers.
