Thank you for buying Ostler. Your license key is on its way to the email address you used at checkout — it is sent as soon as Stripe confirms the payment.

Which computer is Ostler going on?

Download for macOSDownload for Windows

Ostler runs on Apple silicon Macs (macOS 12 or later) and on Windows 10 or 11 — the same license covers either, on one computer at a time. Bookmark this page — the download stays here whenever you need to reinstall.

  1. Install Ostler from the download above.
  2. Open Ostler and paste the whole key from the email when it asks for it.
  3. That’s it — Ostler confirms the key with us over the internet when you activate and every six hours after, so be online for that first moment. Keep the email; the key is also your recovery proof.

No email after a few minutes? Check spam, then write to support@getostler.com and we’ll sort it out.
