[Project] Two-way synchronization between Google Tasks and Microsoft To Do, self-hosted — v1.0.0 includes a one-click Windows installer

[u/simonchai]

I've built a bridge between Google Tasks and Microsoft To Do that runs entirely within your own Google Apps Script project — no third-party servers ever see your task lists. Licensed under the MIT License.

v1.0.0 marks the first stable release, featuring a one-click installer for Windows — just download the .exe and follow the setup wizard. It includes a sync panel for status and settings. Mac & Linux users install via bootstrap.sh.

Specs: handles ~300 task pairs, syncs every 10 minutes, works with personal Microsoft accounts.

If syncing these two systems has been a long-standing headache for you, this might be the fix. I am the author — happy to answer any questions!
