.fi Domain Finder

Finds .fi domain names that are free to register or about to be released, and ranks them by how natural the words are.

Problem

Free and expiring .fi domains come in long lists where most names are unusable, and the good ones are taken before anyone notices.

Value

Someone looking for a domain sees the best available names first instead of reading long lists, and gets a warning before a good name is released.

Written from this project

Role

Product definition, ranking rules for Finnish words, release-timing model and quality checks. Agents wrote most of the code.

  • Defined a ranking that favours familiar, fluent Finnish words and follows the language’s compound and vowel-harmony rules.
  • Built a model that estimates when an expiring domain is released and sends an alert ahead of it.
  • Added a trademark screen so a candidate name is checked before it is registered.
  • Kept a regression test for the ranking so a change in the rules is measured, not guessed.

Limits

  • Describes the product and its ranking only. How the data is gathered, the word lists and the candidate names stay private.
