Browser Compatibility

Zenoti’s web-based software currently supports the following browsers and operating systems:

If you have set up integration with a credit card processing device with any provider other than Zenoti Payments, we recommend disabling any auto-update features of the browser and any dependent technology (like Java) based on the integration you're using.

We do not recommend the use of the following browsers: Internet Explorer, Opera, and Microsoft Edge.


  • If you are using a biometric device, use only Mozilla Firefox
  • Our testing suggests that Chrome provides the best performance when running Zenoti. 

Recommended Operating Systems

Windows: You must use Windows 10 or above, with the latest Windows Updates applied.

Mac: Use Mac OS 10.6 or later

Recommended  CPU

Zenoti will work optimally with Windows machines with Intel i3, i5 and i7 processors. If you run a busy center with a lot of appointments (100+) investing in fast machine will make operations smoother for you.

  • Run a performance benchmark test on https://www.passmark.com/ to check your computer's performance. 
  • The CPU Mark on machines for optimal performance should be greater than 5000 (Typically an Intel i3 Processor or better)

Recommended Memory

Zenoti will work with Windows machines with 4 GB RAM. For optimal performance, we recommend the following:

  • 8 GB RAM for centers that are managing 100+ appointments per day
  • 12 - 16 GB RAM for centers that are managing 200+ appointments a day.

Recommended Screen Resolution

For optimal viewing of the Appointment Book, we recommend that you set the screen resolution to 1280x1024 (in pixels) or higher. Learn how to change the screen resolution here.

Browser Configuration

  • JavaScript must be enabled. Learn how to enable JavaScript here.
  • Cookies must be enabled. Learn how to enable cookies here.

Browser Plugins

We recommend that you do not add many browser plugins as they tend to keep running on the background and eat into your internet speed.
We recommend that you periodically review the browser plugins on your computer and disable the ones you do not require.
Learn how to disable plugin in Mozilla Firefox and Chrome.

Page File Size

If your center manages over 200+ appointments a day, on the drive where the operating system is not installed, we recommend that you set the minimum (initial size) page file size to 1.5x of RAM and maximum to 3x of RAM.
To know how to change the page file size, see the Change the size of virtual memory section of this article.

Internet Speed  


  • Download: 4 Mbps 
  • Upload: 1 Mbps 


  • Download: 8-20 Mbps 
  • Upload: 4-8 Mbps 

Tip: To verify if your internet and hardware meet our recommendations, do the following:

  • Run a test on http://www.speedtest.net/ and confirm the upload and download speed.
  • Run a performance benchmark test on https://www.passmark.com/ to check your computer's performance. The CPU Mark on machines for optimal performance should be greater than 5000 (Typically an Intel i3 Processor or better)

Internet Splitters

If you allows your guests and employees to use the internet at your center for browsing from their personal devices, we recommend that you create two separate networks, one for your guests and employees for their personal use, and one for Zenoti with an internet speed of at least 4 Mbps (recommended 8 Mbps). This way, you can limit the chances of service degradation due to network congestion.

Recommended Receipt Printing Configuration

Zenoti Performance Improvement

Power-saving options in laptop and other devices (that run on battery), slow down the appointment book and other pages in Zenoti. With power-saving option on, whether the device is connected to the external power source, or is working on it's battery, the performance is slowed down. 

Troubleshoot: We recommend you to turn off or disable the power-saving option in your device to improve the performance.
