Is there a free trial without a credit card?

It is a trial in substance, but without the two things people dislike about trials: there is no card on file and no countdown. You get 100 credits when you create the account, they do not expire on a date, and nothing converts to a paid plan on its own. When they are gone the account simply stays free and idle until you decide otherwise.

That is a deliberate choice about how software should be evaluated. An architect judging a rendering tool needs to run it on their own project, not on a demo scene, and needs to do that without a diary reminder to cancel before Friday. Five renders a month is enough to answer the only question that matters: does this produce something I would show a client?

The one thing you need before signing up is an image to work from — a plan, a sketch, a photo or a viewport capture. Archome renders a design you already have rather than inventing one from a description, so without a starting image there is nothing for it to work on.

When the credits run out, nothing happens automatically. No card is charged and no account is suspended. Everything you generated stays in your account; producing more means a paid plan or a one-time credit pack, whenever that makes sense for you.
