Taskwarrior now syncs with Google Calendar and Keep — but only if you’re willing to spend hours in the terminal, hand-craft OAuth tokens, and trust a third-party library that asks for your Google password. The integration isn’t baked into Taskwarrior. It’s not offered by Google. And it doesn’t auto-sync. It’s a fragile, manual bridge built by developers who prefer tw add 'Buy milk' due:tomorrow over clicking through a web UI, and who’ve accepted that syncing means running tw_gcal_sync every time they want their terminal tasks to appear on calendar.google.com.  The setup requires a Google Cloud project, API enablement, client secrets, cookie extraction from browser dev tools, and environment variables set with tokens that gkeepapi warns have full access to your Google account. One-way sync works reliably: add a task tagged remindme in Taskwarrior, run the command, and it shows up in Calendar. Keep sync is shakier. The How-To Geek reporter got tasks from Taskwarrior into a single Keep note, but items created in Keep failed to land back in Taskwarrior due to date parsing errors and missing pass folder configurations. No official Google support. No GUI. No mobile app. Just CLI, config files, and a warning buried in the docs: ‘Protect your master token like a password.’  This isn’t an app launch. It’s a power-user workaround, one that turns Google Calendar into a read-only extension of a decades-old Unix-style task manager. It arrives globally, with no price (Taskwarrior and syncall are free and open source), no release date (it’s been possible since syncall added the integrations), and no vendor backing. What changes? Nothing for most people. For the subset who run Linux, live in the terminal, and refuse to let Google Calendar exist outside their workflow. It means one less tab open. Next step: waiting for someone to wrap this in a systemd timer, or for Google to finally ship a proper CalDAV-compatible API for third-party CLI tools.
