The short version

  • Each has a real cost: Google Authenticator enabling cloud sync moves the security boundary for your 2FA codes to your Google account, so a compromised Google account can expose the same codes syncing was meant to protect.; PartyKit documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms.
  • They diverge on capability: Google Authenticator covers TOTP code generation, PartyKit covers Stateful edge servers.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Google Authenticator

  • Enabling cloud sync moves the security boundary for your 2FA codes to your Google account, so a compromised Google account can expose the same codes syncing was meant to protect.
  • It has no built-in backup export in a portable format, so moving away from Google Authenticator to another app usually means resetting 2FA on every individual service.
  • It lacks organisational features such as folders, search or notes that some competing authenticator apps offer for people managing many accounts.
  • There is no desktop app, so codes must be read off a phone screen when logging in from a computer.
  • If sync is off and the phone is lost without a separate backup, all codes are unrecoverable and every linked account needs its 2FA reset through account recovery.

PartyKit

  • Documentation and FAQ material on the marketing site is sparse compared to larger realtime platforms.
  • Commercial free tier requires deploying to the user's own Cloudflare account, adding setup complexity.
  • Storage on the free Individual plan clears every 24 hours, limiting it to prototyping rather than persistent production data.
  • Smaller ecosystem and community than more established realtime infrastructure providers.

No, it is free with no subscription or in-app purchases.

PartyKit: How much does PartyKit cost?

PartyKit is completely free. Both the Individual and Commercial plans have no upfront costs.

Google Authenticator: Is cloud sync safe?

Google documents it as protected by your Google account security. Whether that is an acceptable trade-off versus device-only storage is debated; you can turn sync off if you prefer local-only codes.

PartyKit: What is PartyKit's Individual plan?

The Individual plan is free and includes deployment to a global edge platform, support for up to 10 live projects, and is suitable for small projects. Storage is cleared every 24 hours.

Google Authenticator: Can I export my codes to another app?

There is no official bulk export; moving to a different authenticator typically requires re-adding each account from its setup page.

PartyKit: What is PartyKit's Commercial plan?

The Commercial plan is free but requires deploying to your own Cloudflare account. It includes custom domains, unlimited projects, and you pay only your Cloudflare usage costs.

Source
PartyKit: Can I upgrade from Individual to Commercial plan?

Yes, both plans are free but offer different feature sets. The Commercial plan removes project restrictions but requires managing your own Cloudflare infrastructure.
