You can try Arbor in the browser right now! Navigate to arbor-sim.org/playground.
This is an Emscripten + Pyodide port of Arbor and is meant to be a simple showcase of neural modelling in Arbor. If you want to do serious work with it, we recommend installing Arbor GUI for a graphical interface to Arbor or the library itself. While Arbor is a stable, robust simulator designed to run large scale simulation on thousands of CPU/GPU nodes, the Playground port comes with some limitations. Notable, only single CPU simulations are supported. Long running simulations may freeze the user interface. Please report any issues on GitHub.
