OAuth vs Keycloak

The security dance everyone hates but can't live without meets the swiss army knife of iam—if you don't mind sharpening it yourself. Here's our take.

OAuth

Nice Pick

The security dance everyone hates but can't live without. Delegating access without sharing passwords, because trust is a token.

Pros

• Eliminates password sharing for third-party apps
• Standardized across major platforms like Google and Facebook
• Granular scopes for fine-grained access control

Cons

• Implementation complexity leads to frequent security flaws
• Token management can be a debugging nightmare

Keycloak

The Swiss Army knife of IAM—if you don't mind sharpening it yourself.

Pros

• Open-source with robust SSO and OAuth 2.0/OpenID Connect support
• Built-in user federation and social login integrations
• Fine-grained authorization policies for complex access control

Cons

• Steep learning curve for advanced configurations
• Can be resource-heavy and tricky to scale in production

The Verdict

These tools serve different purposes. OAuth is a authentication while Keycloak is a hosting & deployment. We picked OAuth based on overall popularity, but your choice depends on what you're building.

The Bottom Line

OAuth wins

Based on overall popularity. OAuth is more widely used, but Keycloak excels in its own space.
