Notion vs Zube: common questions

Which is more reliable, Notion or Zube?

On our scheduled checks, Notion leads on measured uptime — Notion at 100% versus Zube at 0.0% over 90 days. These are our own probe results, not provider claims; the uptime bars above show the day-by-day record for both.

Do Notion and Zube need an API key?

Both ask you to authenticate — Notion uses OAuth and Zube uses an API key. Each key is free to obtain; the Auth and Card-required rows above spell out the signup terms.

Can I call Notion and Zube from the browser?

Only Notion is browser-friendly — it returns CORS headers over HTTPS. Zube needs a server-side call or proxy, so factor that into which one fits a front-end project.

Are Notion and Zube free for commercial use?

Notion has unclear commercial terms, and Zube has unclear commercial terms. We track service terms and the data license as separate fields — see the Commercial use and Data license rows above, and confirm both before shipping either in a paid product.
