Extend your TestCalc projects with powerful compute servers. They give you much more power, GPU support, and flexibility for your computations.

From within your TestCalc project, spin up and connect to a powerful machine. You simply tell your terminals and Jupyter Notebooks to run on these machines. These compute servers open up new possibilities by utilizing enhanced computing resources, extending far beyond the bounds of what you can do in your local project.

These machines optionally come with GPU support. The pre-configured software environments make it very easy to make use of them, right out of the box. These software environments include SageMath, Google Colab, Julia, PyTorch, Tensorflow and CUDA Toolkit, accommodating a versatile range of applications.

Your files are synchronized on demand. Therefore, you can almost seamlessly switch between local and remote computing. You also have much more temporary storage right there on the remote machine.

Usage of these machines is billed by the second. The pricing is highly competitive, starting at under $0.15/hour for computer servers with a GPU!

Read the docs and check out some applications.

TestCalc's file editors are enhanced by large language models like ChatGPT. They help you fixing errors, generate code or LaTeX snippets, summarize documents, and much more.

TestCalc supports many programming languages. Edit the demo cell on the left and evaluate it by pressing "Run". You can also select a different "kernel", i.e. the programming language that is used to evaluate the cell.

TestCalc makes it possible to collaboratively edit computational documents with your colleagues, students, or friends. Edit Jupyter Notebooks, LaTeX files, SageMath Worksheets, Computational Whiteboards and many more with your collaborators in a real-time.

The code code runs in the same environment for everyone, giving consistent results. All changes are synchronized in real-time.

Therefore, you can forget the frustration of sending files back and forth between your collaborators. You no longer waste time reviewing changes and merging documents.

You can think of TestCalc as virtual computer lab in the cloud. It takes away the pain of teaching scientific software.

Hassle-free assignments: TestCalc keeps all files well organized! Due to real-time synchronization you never have to deal with multiple versions of the same file. There is even support for automated grading via NBGrader.

Pre-installed Software like in a computer lab, all software you need is already installed and ready to use.

Real-time Collaboration allows you to virtually look students over their shoulders. You can check their work directly and help them by editing the file or using side-chat communication.
