Authorizer
Authorizer is completely free and open-source. There are no subscription fees, no per-user charges, and no hidden costs. You can download the software, deploy it on your own infrastructure, and use it for unlimited users without paying anything.
Free (Self-Hosted): Since Authorizer is open-source under the MIT license, you get all features included. You only pay for your own hosting costs (server, database, email service for verification emails). This could be as low as a few dollars per month on cloud providers like Railway, Heroku, Render, or DigitalOcean.
The project is maintained by an active community and accepts sponsorships on GitHub if you want to support development. You can also get community support through their Discord server and GitHub issues for free. This makes it perfect for startups and businesses that want to avoid the high costs of services like Auth0 that charge per user.
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.
