Amba is the agent-native backend for mobile apps: one backend — identity, engagement, gamification, economy, social, analytics, and infrastructure — that an AI coding agent provisions and wires in about 30 seconds over a hosted MCP server. Auth0 (now part of Okta) is a developer-first identity platform: Universal Login, social and enterprise connections, MFA, SAML/OIDC, B2B organizations, and a strong new “identity for AI agents” story. It is identity only — as of mid-2026 it ships no database, push, content, economy, social, or analytics — so an engagement app still needs an entire backend around it. What is an agent-native backend?
Amba vs Auth0, capability by capability.
● built-in · partial = limited / add-on · — not offered. “Agent installs the whole backend” means the MCP surface is an entire app backend, not read/write access to one product.
Which should you choose?
- You want auth included in your backend, not a separate per-MAU bill on top of everything else.
- You need the rest of the app — push, segments, streaks, economy, subscriptions, social — not just login.
- You want an agent to install identity and the backend together in one step.
- You need enterprise identity depth: SAML/OIDC SSO, advanced MFA, fine-grained authorization, B2B orgs.
- You’re building delegated agent-identity flows (Token Vault, Auth for MCP) and want the most mature option.
- Identity is a standalone concern you want decoupled from your app backend.
Scope: one box vs. the whole backend
Auth0 is identity and nothing else. To ship a consumer app you pair it with a database, push provider, segmentation tool, content layer, billing provider, and analytics. Amba’s overlap with Auth0 is just the auth slice — Amba also includes everything after login as one coherent backend the agent installs.
Mobile auth that survives reinstalls
Amba’s identity covers anonymous sessions, email, Sign in with Apple, and Google, with post-hoc provider linking so a guest becomes a real user without losing data — plus roles, scopes, refresh tokens, and device-bound sessions. It’s drop-in mobile auth, not a general-purpose identity suite, but it’s wired to the rest of the backend by default.
Per-MAU cost
Auth0 is known for steep per-MAU scaling on its B2C and B2B tiers. With Amba, auth is included in the per-project price alongside push, data, economy, and analytics — you’re not metering login separately from the product it gates.
Where does Auth0 beat Amba?
Auth0 outmatches Amba on the depth and rigor of identity: enterprise SSO, advanced MFA, fine-grained authorization, compliance posture, and a far more mature agent-identity and delegation story (Token Vault, Auth for MCP). If identity is your hardest problem, Auth0 is purpose-built for it.
Moving from Auth0 to Amba
If you only used Auth0 for social/email login, Amba’s auth covers it directly and you fold identity into the same backend as push, data, and economy. If you rely on enterprise SSO or advanced authorization, keep Auth0 for identity and use Amba for the rest of the backend.
Pricing context: Auth0: free up to ~25,000 MAU, then B2C/B2B tiers that scale per MAU (B2C Essentials from ~$35/mo, Professional from ~$240/mo). Amba: auth is included in per-project pricing (Free, $20, $200). Verify Auth0’s current tiers.
Amba vs Auth0 — FAQ
Is Amba an Auth0 alternative?
For mobile apps that need auth plus a backend, yes. Amba includes mobile authentication (anonymous, Apple, Google, email, with linking) as part of a full backend, so you don’t pay for and integrate identity separately from push, data, economy, and analytics.
Does Amba support Sign in with Apple and Google?
Yes. Amba supports anonymous sessions, email, Sign in with Apple, and Google, with post-hoc account linking so an anonymous user can become a real user without losing data, plus roles, refresh tokens, and device-bound sessions.
Does Amba replace enterprise SSO like Auth0?
No. Amba’s identity is drop-in mobile auth, not an enterprise identity suite. For SAML/OIDC SSO, advanced MFA, and fine-grained authorization, Auth0 is deeper; many teams keep Auth0 for identity and use Amba for the rest of the backend.
