Platform/Authentication

Authentication, out of the box

Drop-in user management, sessions, and role-based access with a built-in admin dashboard — so you can ship secure apps without reinventing auth.

What’s included

  • Email + password and OAuth sign-in flows ready to use
  • Social sign-in with Google, GitHub, and more
  • Stateful sessions with secure cookies — no integration required
  • Role-based access control (RBAC) for users, teams, and permissions
  • Built-in admin dashboard for managing users and roles
  • Email verification and password reset flows

Auth is part of the framework

With Modelence, authentication is set up in the full-stack framework from the moment you start building. The user object, session handling, and login flows are already there. Tell the builder what you want — “users must log in with email and password,” “support Google login,” “only admins can see this page” — and it puts the right code in your app. No separate account to create.

Auth is there all along

You don’t connect it as a separate step. You don’t plug it into the flow. When you ask Modelence to build an app with user accounts, it builds a structured authentication system as part of everything else — the database, the session management, the login and logout forms, the protected pages. It’s built in from the outset.

Everything in one place

Other tools make you pick an auth service, create an account, and link it to your app — then manage two services as you build. Modelence is one product. Auth lives in your code, on your server. No Auth0 login, no Clerk dashboard, no separate OAuth app to set up.

Auth in simple English

Want admins to see a dashboard users don't? Need a client portal separate from an admin portal? Describe access in plain English. The builder puts those rules in your app — not in an external configuration layer that drifts out of sync with your data model.

The AI agent can see your auth layer

The AI agent has full visibility into how authentication is implemented. If a session expires too soon, a route is reachable when it shouldn't be, or a login flow fails on an edge case — the agent reads the code, finds the problem, and fixes it. No black-box integration to reverse-engineer.

Your users stay in your app

With a third-party auth service, your user identities live in someone else's database. With Modelence, user data sits in yours. Query it, extend it, link it to app data, and bring it with you if you ever move. No export step. No provider dependency. Yours from day one.

What the difference looks like in practice

Every row below is a real scenario. The left column is what building auth looks like on a prototype-first builder. The right column is what it looks like on Modelence.

Setup time
Adding auth separately
Sign up for Auth0 or Clerk. Read the docs. Configure OAuth. Wire in API keys. Debug the integration.
Modelence built-in auth
Prompt: “add user login.” Done. Auth is live from the first build.
Accounts to manage
Adding auth separately
Your app + a third-party auth provider + however many OAuth apps you've registered.
Modelence built-in auth
Just Modelence. One platform, one account, everything in one place.
When auth breaks
Adding auth separately
You debug across two services. Is it your app? The provider? The API key? The OAuth config?
Modelence built-in auth
Auth is part of the framework. The AI agent can see inside it and fix it directly.
User sessions
Adding auth separately
Managed by the auth provider. Surfaced to your app via tokens. Complex to debug.
Modelence built-in auth
Sessions are part of your app. Queryable. Visible. Consistent with everything else.
Role-based access
Adding auth separately
Configure it in the provider, sync it to your app, and keep them in sync as features change.
Modelence built-in auth
Describe access rules in plain English. The builder implements them in your codebase.
Cost
Adding auth separately
Auth provider subscription on top of your builder subscription. Two bills.
Modelence built-in auth
Included. No separate auth provider required.

The apps that need real auth

Auth isn’t exciting on its own. But when it’s already done, you can get on with building the app.

SaaS

Client-facing SaaS platforms

Customers need to log in and see their data — not someone else's. That means users, sessions, and per-user data. On Modelence, that's the first thing in place, not the last thing before launch.

CRM

CRMs and pipeline tools

FundCRM — a VC pipeline tool built on Modelence — keeps deals, contacts, and activity logs scoped per user. Auth isn't bolted on; it's what makes per-user data possible. With Modelence, it was there from the first build.

Marketing

Marketing automation platforms

Mailvora, an email marketing tool on Modelence, stores recipient lists and send history per account. Multiple users, data segregation, role-based access — none of which required wiring up an auth service.

Internal → Product

Internal tools turning into products

On most builders, adding auth at this stage is an integration project. On Modelence, you tell the builder to add users — and the prototype is now a product, with logins, roles, and per-user data already in place.
