Can I use StreetJS together with Auth0?

Yes. StreetJS can validate Auth0-issued tokens and offers an Auth0 plugin, so you can use the managed identity provider while StreetJS handles the rest of your backend.

StreetJS vs Auth0

Q: Can StreetJS replace Auth0 entirely?

For many applications, yes: JWT, sessions, RBAC, and MFA are built in. Auth0's hosted SSO, social connectors, and compliance certifications are not replaced for free; you would build and operate those yourself.

In one line: This is a build-and-self-host vs buy-managed decision. Auth0 is a managed identity provider you integrate with; StreetJS ships authentication (JWT, sessions, RBAC, MFA) as built-in primitives you own and run yourself — and can still integrate Auth0 via a plugin if you prefer the managed route.

Not a like-for-like comparison. Auth0 is a hosted identity service; StreetJS is a backend framework. They overlap on the auth layer, which is what this page compares.

At a glance

	StreetJS (built-in auth)	Auth0
Model	Self-hosted primitives in your app	Managed, hosted identity provider
JWT / sessions	Built in (AES-256-GCM sessions)	Issued and managed by Auth0
RBAC	Built in	Roles & permissions (managed)
MFA	Built in	Built in (broad factor support)
Social / enterprise SSO	DIY or via plugins	Extensive out of the box (OIDC, SAML, social)
Where data lives	Your database	Auth0 tenant
Cost model	Your infra cost	Per-MAU subscription
Compliance certifications	Your responsibility	SOC 2, ISO, etc. provided
Vendor lock-in	None	Migration effort to leave

Where Auth0 wins

Breadth of identity features out of the box: dozens of social/enterprise connectors, OIDC/SAML SSO, anomaly detection, and a hosted login UI.
Compliance offload. SOC 2 / ISO certifications and security operations are handled for you.
Less to build and maintain — identity is a deep domain; Auth0 covers edge cases you’d otherwise own.

Where StreetJS wins

You own the data and the cost curve. No per-MAU pricing; auth runs inside your app against your database.
No third-party dependency or lock-in for core auth flows.
Integrated with the rest of your backend — guards, RBAC, and sessions are part of the same typed framework, not an external round-trip.

Honest tradeoffs

If you need enterprise SSO, a hosted login experience, broad social connectors, or compliance certifications handled for you, Auth0 saves significant time and risk. If you want to avoid per-MAU costs and vendor lock-in, keep identity data in your own database, and you’re comfortable owning auth, StreetJS’s built-in primitives are a strong fit. You can also use the @streetjs/plugin-auth0 integration to combine StreetJS with Auth0 if you want both.

FAQ

Can StreetJS replace Auth0 entirely? For many apps, yes — JWT, sessions, RBAC, and MFA are built in. But Auth0’s hosted SSO, social connectors, and compliance offload are not something a framework replaces for free; you’d build and operate those yourself.

Can I use StreetJS with Auth0? Yes. StreetJS can validate Auth0-issued tokens and there is an Auth0 plugin, so you can adopt the managed IdP while still using StreetJS for the rest of your backend.
