A Namelix alternative built around the domain check
Namelix is the closest tool to Domainium: both use a language model to invent short, brandable names instead of stitching keywords together. The difference is what happens after the list appears. Domainium checks every single suggestion live across 50+ extensions, surfaces premium and aftermarket listings, and exposes the same engine through an API and an MCP server.

What Namelix does well
Namelix is a free naming tool from the team behind Brandmark, and it earned its reputation. It is the reference point for anyone who wants invented, brandable names rather than keyword mashups.
- A custom language model tuned for short, brandable, invented names.
- Filters for name length, keyword usage and preferred extensions.
- Saving a name teaches the algorithm your taste, so later batches sharpen.
- Completely free to use, with a companion logo product from Brandmark.

When Namelix is the better choice
Stay with Namelix if you want an unlimited free idea machine and you are happy checking domains yourself afterwards, or if you plan to buy a logo from the same family of tools.
When Domainium is the better choice
Choose Domainium if the bottleneck is availability rather than ideas: you want a shortlist where every name already has a registerable domain, or you want to call the naming engine from code or from an AI agent.
Frequently asked questions
Is Domainium a direct Namelix alternative?
Yes, both generate short brandable names with AI rather than combining keywords. The practical difference is that Domainium resolves domain availability live on every suggestion across 50+ extensions, so the shortlist you end up with is already filtered by what you can register.
Namelix is free, why would I pay?
Domainium is free to start too: 10 AI searches every month with no credit card. Paid credits only matter during an intensive naming sprint or when you call the API, and they are one time packs at 4.99 EUR or 9.99 EUR rather than a subscription.
Can I use both tools together?
Plenty of founders do. Brainstorm widely in one tool, then run your favourites through a live multi TLD check before you commit to a brand. Domainium is designed for that second step as much as the first.
Does Domainium make logos?
No. Domainium covers naming and domain availability only. If you need a logo and a full brand kit in the same purchase, a branding suite is a better fit.
