If you want to play Catan online without spending anything, you've got a few options, and they don't all work the same way. Here's what each one offers for free, and where they start asking you to pay.
Catan Universe: the official version
Catan Universe is the brand's official app and website, available on Android, iOS, Mac, Windows, and browser, with one account working across every device. You can play against friends worldwide or against the AI.
The catch: the free version limits you to a single map and game mode. Unlocking the rest of the boards and expansions (Seafarers, Cities & Knights...) requires payment.
Colonist.io: the most popular free alternative
Colonist.io is probably the most popular unofficial implementation in the genre. It runs straight in the browser, no download or mandatory registration, with games for up to 8 players. The basic mode is free, includes games against AI, and also has a ranked mode for players looking for something more competitive.
Board Game Arena: Catan among a thousand other games
Board Game Arena is a platform with over a thousand board games playable from the browser, Catan included. The upside is having everything in one place if you enjoy other board games too; the free tier usually comes with usage limits that lift with a premium account.
Hexo: an independent alternative inspired by the genre
Hexo isn't a version of Catan and has no official affiliation with the brand: it's its own hexagonal strategy game inspired by the same settlement-and-building genre. You can play straight from the browser, against the AI or with friends, with nothing to install.

If you want the exact Catan board and rules with the official seal, Catan Universe is your option, even with limits on the free tier. If you'd rather jump straight into a browser game with no registration, Colonist.io or Hexo get you playing right away.
Try a game against the AI on Hexo at /play/ai or open a private room with friends at /rooms and see which one fits what you're looking for.
