Don’t Be Late

Don’t Be Late is a free, open-source Chrome extension that opens your Google Calendar meetings in a browser tab shortly before they start, so that joining is a single click.

One minute before each meeting (you can choose 0–10 minutes), the meeting’s Google Meet waiting room, or its Zoom or Microsoft Teams link, opens in a new tab and the browser window comes to the front.

Features

• Works with any number of Google accounts, both personal and Google Workspace.
• Opens only meetings with a video link that you haven’t declined. All-day, out-of-office and focus-time events are skipped.
• Opens Google Meet with the account whose calendar the meeting is on.
• If the meeting is already open in a tab, brings that tab to the front instead of opening another one.
• Still opens a meeting shortly after its start if the computer was asleep.
• Can be paused for an hour or until tomorrow.

How it works

You connect your Google accounts on the extension’s settings page and grant it read-only access to your calendar events. The extension then checks your primary calendars for upcoming meetings every few minutes. Your calendar data stays in your browser: it’s sent only to Google, never to the developer or anyone else.
