Choose the version compatible with your Mac (Apple Silicon or Intel).

Why Choose Tesmon Desktop?

  • Secure & Private: All tasks and data remain local; Tesmon has zero access to your data.
  • Comprehensive: It’s a one-stop solution, packed with a plethora of features catering to various development and testing needs.
  • Designed Around TesmonLang: Every interaction within Tesmon Desktop extends naturally for automation testing to Tesmon Cloud.

How is Tesmon Desktop Different?

Tesmon Desktop leverages the power and simplicity of TesmonLang, a dynamic language constructed to streamline your development workflows. In contrast to no-code solutions which might be adequate for creating 5-10 test cases through UI elements, drag-and-drops, and buttons, Tesmon Desktop is consciously designed for scalability. Imagine managing 50, 100, or even 1000 test cases; Tesmon Desktop is engineered to handle such volumes efficiently, making it a versatile choice as your project grows.
