$20 free credit is applied automatically at signup and is valid for 1 month. Credits are used first — you won't be charged until they run out or expire.

A credit card and billing details are required to complete setup (identity verification) — no charge while credits last.

Static site hosting is always free, even after the credit expires: 100 sites, 1 GB per site, 100 GB bandwidth and 600 build minutes per month.
