Resource limits


Currently, there is a limit of 300Mb space for Laravel notebooks and 150Mb space for Interactive and Standard notebooks. We will expand on this in the future as we have more resource at our disposal.

Memory (RAM)

There is a memory limit of 100Mb for Standard notebooks and 300Mb for Laravel notebooks. We choose to allocate more for Laravel notebooks since it needs more resource at bootstraping point than other notebooks.

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.
