I Released a Mac App That Automatically Opens Your Meetings

I’ve just released Galopen.

It’s a simple Mac app that automatically opens Zoom, Google Meet, and other meeting links right when your scheduled time arrives.

Previously, I released apps like Macopy and Mac Classic Player.

All of them were built with Electron. While they worked fine, they had one major downside: the app size was ridiculously large for what they actually did.

So recently, I decided to replace everything with Tauri.

Functionally, nothing has really changed.

Galopen is also built with Tauri.

Since it’s still a relatively young framework, debugging wasn’t always smooth. That said, the app size is dramatically smaller.

Compared to Electron, the bundle size is roughly one-fifth. Startup time is faster too.

For lightweight desktop apps, Tauri feels more than capable.

This app was heavily inspired by the Chrome extension crx-gcal-url-opener.

However, as a Firefox user, I couldn’t find a proper Firefox equivalent.

So I figured — why not just build a standalone app instead?

To be honest, about 99% of the implementation and design was handled by Claude Code, so I don’t even fully grasp every implementation detail myself.

That said, the core logic is simple.

It reads events from the macOS Calendar, then polls and opens the meeting links at the scheduled time.

If anything, I’m more surprised that there aren’t many similar apps out there.

Since it relies on the macOS Calendar, it naturally supports multiple accounts.

That’s actually a huge advantage compared to browser extensions, which often struggle with multi-account setups.

It’s completely free to use, so feel free to give it a try.
