Extend your TestCalc projects with powerful compute servers. They give you much more power, GPU options, 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, or with one click launch JupyterLab or VS Code. 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 servers optionally come with very competitively priced GPU support, from a single NVIDIA T4 to eight H100's, with many options in between, including L4 and L40, RTX-A4/5/6000, and A100 with 40GB and 80GB. The finely configured software images include Google Colab, SageMath, Anaconda, Julia, PyTorch, Tensorflow and Open WebUI, accommodating a versatile range of uses. The pre-configured software environments make it very easy to make use of them, right out of the box. You can also run any command as root, install anything you want, and use Docker and Kubernetes.

Your files are synchronized. Therefore, you can seamlessly switch between different servers. You also have much more disk storage on the remote machine.

Usage of these machines is billed by the second. The pricing is highly competitive, starting at under $0.01/hour and under $0.15/hour with a GPU!

Read the docs and check out some applications.

A wide range of Generative AI Large Language Models are highly integrated into TestCalc. This helps you fix errors, generate code or LaTeX snippets, summarize documents, and much more.

With TestCalc, you can easily collaborate with colleagues, students, and friends to edit computational documents. We support Jupyter Notebooks, LaTeX files, SageMath Worksheets, Computational Whiteboards, and much more. We have an open world approach giving users as much flexibility in choosing software and hardware as possible.

You and your collaborators use the same per-project environment, which provides consistent results, synchronized file changes, and automatic revision history so that you can go back in time when you need to discover what changed and when. You can even publish your TestCalc creations to share with anyone via the built-in share server.

Forget the frustration of sending files back and forth between your collaborators, wasting time reviewing changes, and merging documents. Get started with TestCalc today.

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.
