Resource footprint
Needs ~128 MB RAM · 512 MB recommended(estimated)
Why?
- Minimum XS (256 MB): estimated from the app's language, dependencies and category: about 128 MB. We add 25% headroom on top.
- Recommended S (512 MB): the project's docs ask for 2 GB for the whole server (docs/admin/Installation.md); about 1.8 GB of that is for the app itself. Until we've measured it, we recommend at most one size above the minimum.
- It can sleep when idle, which is the cheapest way to run it.
