Runtime Environment

PHP Versions

PHPSandbox uses PHP v7.4 and v8.0(default) to run all notebooks at the moment.We advise that any packages or projects that will be used are compatible with these php versions.You can switch between these versions on the notebook page.

Resource limits

Disk

At present, there exists a restriction of 1024Mb storage capacity for all notebooks, whereas premium notebooks offer a larger disk space of 2048Mb. As we gain access to additional resources, we plan to enhance this limitation in the future.

Memory (RAM)

All notebooks currently have a memory constraint of 512Mb, whereas premium notebooks provide a higher memory capacity of 1024Mb.

File Synchronization

Files created that are more than 10Mb are not synchronized with the frontend app. This means that you cannot see them at the frontend app but it remains on your disk and can be refrenced.

Premium Notebooks

Subscribing to any of our premium plans gives you higher compute resources for your notebooks. The details can be seen here.
