Hi folks! Just getting my feet wet with identity management after moving into DevOps. We're building a SaaS product on AWS (ECS, RDS, typical stack) and need to pick an auth provider for our ~200 internal and early customer users.
I'm looking at Auth0 vs Okta. My main concerns are:
- Cost for this scale
- Ease of integrating with a React frontend and a Go backend
- AWS ecosystem fit (e.g., securing API Gateway, Lambdas)
I set up a quick Auth0 POC and got a basic login working. Here's my Go snippet for validating the JWT:
```go
func validateToken(tokenString string) (*jwt.Token, error) {
token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error) {
// Verify signing method and fetch key from JWKS
if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok {
return nil, fmt.Errorf("unexpected signing method")
}
certs, err := fetchJWKSCerts(auth0Domain)
return certs, err
})
return token, err
}
```
But I'm not sure about long-term pricing or if Okta's device management might be overkill for us. Has anyone been through this decision for a small-to-mid SaaS? Any big "gotchas" with either at this scale? Would love to see real-world configs or dashboards if you have them.
I'm a lead engineer at a ~150 user B2B SaaS on AWS, and we've been running Auth0 in prod for 3 years after ditching a homegrown system.
Target audience: Auth0 feels built for devs in companies like yours. Okta feels like it's built for IT departments at companies 10x your size. The difference is in the UI: Auth0's dashboard is about configuring auth flows; Okta's is about managing user directories and devices.
Real pricing gotcha: Auth0's "Actions" and "Organizations" are now paywalled features. You'll start on the free tier, but the moment you need custom login logic or proper multi-tenancy, you're looking at their "Professional" plan, which was ~$1300/month for us last I checked. Okta's published pricing is more opaque, but their sales push starts around $4/user/month for their foundation, and you'll need add-ons. Both will easily run you $2000+ annually for 200 users.
Integration effort: Auth0's React SDK and Go libraries are straightforward. Their documentation is geared towards making a POC work fast. Okta's docs felt more like enterprise software manuals, with more steps for tenant configuration and policy setup before you write a line of code.
Where it breaks: Auth0's rate limits on their free/low tiers are real. We hit them during a marketing push. Okta's limitation is complexity; you'll spend time navigating features you don't need (like device trust) to configure the few you do.
I'd pick Auth0 for your described case, purely because the initial developer experience is faster for a small team. But tell us your exact multi-tenancy needs and if you need to authenticate anything besides humans (like service-to-service). That's where the real cost divergence happens.
