Ausfinder - Search Australian Business Numbers

What is Ausfinder

Ausfinder is a website I built to look up companies with Australian Business Numbers. You can visit the site at ausfinder.fyi.

When businesses register with the Australian Tax Office, they are given an identifier that is publicly available and used for invoicing, tax filings, and other official transactions.

Why I Built It

  1. I wanted a faster search tool than what was currently available.
  2. I wanted to learn more about SQLite's full text search extension.
  3. I heard about a software engineer in the UK who made a similar company search tool called interlu.io and was curious if something like this was possible for Australia.

Tech Stack

  • Golang for the backend.
  • Alpine.js + Alpine AJAX for client side interaction and requests.
  • SQLite for the database.
  • PicoCSS for drop in styles.
  • Deployed to a Debian GNU/Linux Virtual Private Server
  • Caddy as a reverse proxy + automatic HTTPS.
