| Which plan to pick | Build on Hobby. It's enough until you have customers who care about the Clerk branding or need multi-factor login, then move to Pro. Business only matters when a customer asks for a SOC 2 report. | Put your site on the free plan. It covers speed, SSL and security for most small businesses. If you host an app on Workers, the $5 a month Workers Paid plan lifts the limits. Pro and Business only make sense when you need their image tools, support or uptime guarantee. | Start on Free. Move to Professional when you launch, mainly for daily backups and the bigger limits. Business is a big jump aimed at teams of 50 or more, so most readers will never need it. |
