Is the name you picked
actually free to use?
One name, three answers: the domains, the social handles, and whether someone already holds the US trademark. Free, no account.
Domains
Checked across .com, .io, .ai, .app, .dev, .co — with the registry lifecycle for the ones already taken.
Handles
GitHub, TikTok, YouTube, Reddit, X and Instagram — so the name is usable everywhere, not just on the web.
Trademark
A knockout search of public USPTO records, linked back to the official source. Not legal advice.
A domain being free doesn't mean the name is. Plenty of founders register the domain, launch, and then get a cease-and-desist — this is the 30-second check that catches it.
