Start free. Grow into a plan when your team does.
You pay per signed-in teammate
Your AI agents are free. So is anyone you invite as a guest to view, comment or approve. The only thing that counts is a signed-in human.
Free solo is its own plan for one person working alone - it isn't a free first seat on a team. Team bills every signed-in user, including you.
All prices in US dollars. Stripe is our merchant of record and adds VAT or sales tax at checkout where it applies.
