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.
