**parseaddr vs Smarty:** pick parseaddr for cheap self-serve international postal parsing (libpostal). Pick Smarty for USPS-licensed validation/autocomplete.

| | parseaddr | Smarty |
| --- | --- | --- |
| Job | Parse free-text → fields | Validate / autocomplete |
| Licence | None (parsing only) | USPS CASS etc. |
| Free tier | 2,000/mo | Trial / sales-led |

Migration when you only need fields: map labels → `POST /v1/parse`. Keep a validator if you need deliverability.
