Spec score 8.0 #11 of 30 in Address Verification Software

What it is

Addressr provides Australian address search, validation, and autocomplete through an API or self-hosted software. It uses G-NAF, which its maker describes as Australia's authoritative address database with more than 15 million addresses. Search covers addresses, localities, postcodes, and states or territories. Results include a stable address identifier, and an address-detail endpoint returns structured fields and available geocoding. Teams can use the hosted API through RapidAPI or run the software on their own infrastructure. RapidAPI handles signup, API keys, billing, and plan changes; current hosted prices and request limits are available there. Self-hosting requires Node.js 22 or newer and OpenSearch. The first full data download and index takes about an hour, depending on the machine and options. G-NAF is released every three months, and the maker recommends scheduling updates for a self-hosted index. Optional latitude and longitude geocoding for self-hosting requires more memory and increases indexing time. The self-hosted software is free at free under an Apache-2.0 licence, but the team supplies its infrastructure, hosting, monitoring, and data updates. Addressr also documents an MCP package for Claude, Cursor, VS Code Copilot, and other compatible assistants.
