It's unclear what it is you think Atlas gives you and therefore what you would consider an alternative. If you're in US, you can accept Stripe Payments without a company. You can accept money in your own name or by registering DBA and using that as a name. Stripe Atlas automates creating an LLC for exceedingly low price. If you're in US it would be hard to find a better deal but if you really don't want to spend $500 on Atlas then you can do all they do manually. It won't be free, there are fees you have to pay anyway. And figuring out what paperwork to submit and filling it out (without paying some professional for advice) will be painful. Atlas is most attractive for people outside US that want a US identity because Stripe Payments (and others) don't support merchants in every country.
