1.2.2 Gitpod resources

Gitpod gives you 500 free credits per month, which is equivalent to 50 hours of free environment runtime using the standard workspace (up to 4 cores, 8 GB RAM, and 30 GB storage).

There is also a large workspace option that gives you up to 8 cores, 16GB RAM, and 50GB storage. However, the large workspace will use your free credits quicker and you will have fewer hours of access to this space.

Gitpod will time out after 30 minutes of inactivity and will save your changes for up to 2 weeks.
