Gotchas

Sleeps after inactivity

Free-tier Spaces automatically go to sleep after a period of inactivity and cold-start on the next request, making always-on services unreliable.
CPU Basic only (2 vCPU / 16 GB)

Free hardware is limited to 2 vCPU and 16 GB RAM; GPU acceleration starts at $0.40/hr and is not available on the free tier.
No persistent disk

The 50 GB disk attached to free Spaces is ephemeral and wiped on each restart; persistent storage requires a paid add-on.
No protected/private visibility on free

Protected Space visibility (private source, public app) requires a PRO or Team/Enterprise plan; free users get only public or fully private Spaces.
Port access restricted to 80/443/8080

Outbound network requests are limited to ports 80, 443, and 8080; other ports are blocked.
No GPU on free tier

All GPU hardware tiers (T4, L4, A10G, A100) are pay-as-you-go and unavailable on the free CPU Basic plan.
Unlimited public Spaces

There is no published cap on the number of free CPU Spaces a user can create; usage is effectively unlimited for public demos.
