Supported Platforms

Backends

iTwin.js backends are built and tested on the following:

  • Arch Linux
  • Debian 11 "Bullseye"
  • Windows 10 version 1803 (or greater)
  • MacOS 10.15 (or greater)

They should run on most Windows, Linux and MacOS versions with Tier 1 support from Node.js. However, regular testing only occurs on the platforms listed above.

Supported Browsers

iTwin.js strives to support as many modern browsers as possible, though it requires JavaScript ES2023 support. The quality of the web browser's WebGL implementation has a substantial impact on display performance.

  • Chrome (recommended for development)
  • Firefox
  • Safari
  • Opera
  • "New" Chromium-based Edge

Note: Internet Explorer and "Old" Edge are not supported

Note: Other Chromium-based browsers will likely work fine, but are untested.

Electron

To enable the development of desktop applications, iTwin.js supports the latest Electron releases. As of iTwin.js 5.0, Electron 33 is the minimum requirement. See Electron platform requirements for supported Windows, Linux and MacOS versions.

Mobile Native

The following minimum versions of mobile operating systems are supported:

  • iOS 17: Minimum supported iPhones and iPads
  • Android 9.0 (API Level 28)
