Stack Auth
Stack Auth offers transparent pricing that scales with your needs. The Free plan is perfect for individuals and small projects, supporting up to 10,000 users with unlimited projects and teams. You get one dashboard administrator and access to all core authentication features.
The Team plan costs $49 per month and increases your user limit to 50,000 users. It includes three dashboard administrators, with additional admins available at $49 each. This plan is ideal for early startups and small teams building their products.
The Growth plan at $299 per month removes all user limits entirely. You get unlimited users, projects, and teams, along with five dashboard administrators included. Additional admins cost $49 each. This plan is designed for growing businesses that need to scale without worrying about user count restrictions.
All plans include the same core features, with the main differences being user limits and admin accounts.
