Choose casdoor if…
- casdoor is primarily Go; RulesEngine is C#.
- License: casdoor is Apache-2.0, RulesEngine is MIT.
- Tags unique to casdoor: agent, agi, ai-gateway, auth.
- Also covers AI Agents.
- casdoor ships Docker support for self-hosted deployment.
- When you require a comprehensive IAM tool that supports multiple authentication methods such as OAuth, OIDC, SAML, CAS, LDAP, and more.
When NOT to use casdoor
- If your project requires proprietary technology exclusivity and cannot utilize open-source tools like Casdoor licensed under Apache-2.0.
- When the depth of integration with specific authentication methods (e.g., some advanced SAML configurations) is critical, and you find that other competitors offer more specialized or better-detailed/
- +customizable versions of support for those methods.
- If your environment strictly requires closed-source components for security reasons, thus Casdoor would not be a suitable choice due to its open nature.
Choose RulesEngine if…
- RulesEngine is primarily C#; casdoor is Go.
- License: RulesEngine is MIT, casdoor is Apache-2.0.
- Tags unique to RulesEngine: c#, dotnet, engine, expression-evaluator.
When NOT to use RulesEngine
