FAQ

How does domainsearch.sh compare to Instant Domain Search?

Both are fast and check availability live. domainsearch.sh adds a transparent score for every suggestion, keeps available names front and center rather than surfacing marketplace listings, and offers a free semantic expansion mode.

Is it as fast?

Yes. The suggestion engine is deterministic and CPU-only, and results stream in live so available names appear as they are found.

Does it show premium or aftermarket domains?

It labels status (available, taken, or premium) clearly and orders available names first, without pushing a marketplace.

Is there an API?

The engine is built to be consumed programmatically, with fast streaming responses suitable for apps and AI agents.
