20,000 files and 100 Workers on Free; 25 MiB per file; must stay under the Worker request quota only if a script runs (run_worker_first / SSR). Static-only assets do not count against that quota at all. |

| Interface | rest, cli rest |

| Tooling | wrangler deploy with an assets binding (wrangler 3.78.10+); Workers REST API; static assets can be deployed with no Worker script logic, so serving is purely static. |

| Composes with | 100 Workers on the free plan x 100,000 files (paid) or 20,000 files (free) x 25 MiB. Separate bucket from Pages on the same account, so a single free account presents Pages (100x20k) + Workers (100x20k) file slots. Unlimited accounts multiply further. |
|---|
| Reliability | Free-tier 429s apply to script-invoking routes only; purely static paths keep serving. No eviction window documented for assets — they live as long as the Worker version. |
