Built for AI app builders

Your AI App Is Smart. Your Auth Should Be Too.

Stop duct-taping login onto LLM features. Ship secure auth, OAuth, sessions, and billing in minutes - not weeks.

The problem

You’re Shipping AI Features, Not Security Infrastructure

You want to fine-tune prompts, optimize latency, and improve output quality. Instead, you’re debugging password resets, token expiry, and OAuth callbacks. Auth slows down your actual product work.

Edge Cases Break Fast-Growing AI Apps

Magic links fail. Sessions expire mid-generation. Users hit usage limits but stay logged in. Multi-tenant data leaks become real risks. AI apps scale unpredictably - and DIY auth cracks under pressure.

Monetization + Access Control Gets Messy

You need paid tiers, usage limits, team workspaces, API access, and role-based permissions. You start stitching Stripe webhooks, session flags, and database checks together. It works - until it doesn’t.

How Simple Login helps

Drop-In Auth Built for Modern AI Stacks

Add secure login, OAuth, and session management without building it yourself. Your AI app gets production-grade authentication from day one - without slowing feature velocity.

Handles the Weird Stuff So You Don’t Have To

Session rotation, token security, multi-tenant isolation, OAuth edge cases - handled. Your AI app stays stable even as usage spikes or pricing models evolve.

Built-In Access Control + Payments

Gate features by plan. Control API usage. Support teams and workspaces. Sync payments with authentication automatically. Monetization becomes configuration - not custom backend glue.

Key features for AI app builders

Email/password, magic link, and social OAuth providers out of the box
Secure session management with rotation and revocation
Multi-tenancy support for team-based AI tools and workspaces
Role-based access control for admins, members, and API users
Stripe integration for subscriptions and usage-based billing
API token support for AI-powered developer platforms
Production-ready security defaults (CSRF, rate limiting, secure cookies)
Simple SDK + clean REST endpoints for fast integration

"We stopped fighting auth bugs and focused on improving our AI output. Setup took hours, not weeks."

Your AI Product Is Complex Enough

You’re already managing:

Auth shouldn’t be another fragile subsystem.

AI apps are different. Users trigger long-running processes. They reconnect to streaming outputs. They upgrade plans mid-session. They invite teammates to shared workspaces. Traditional boilerplate auth doesn’t account for this behavior.

You need authentication that understands:

That’s what Simple Login is built for.

Built by Builders, For Builders

You don’t want auth theory. You want something that works in production.

Simple Login is built by developers who’ve shipped SaaS products. It’s designed for teams who:

You plug it in. It handles the rest.

Works With Your Stack

Whether you’re building with:

Integration is straightforward. No opinionated lock-in. No forced UI. Use your own frontend. Keep control of your data.

You stay focused on:

Not password hashing strategies.

AI Apps Need Real Security

AI tools often process:

A weak auth system turns into a liability fast.

Simple Login gives you:

Without you stitching middleware across five repos.

Monetize Without Glue Code

AI apps almost always monetize through:

Instead of wiring Stripe events to custom flags and hoping it stays in sync, authentication and billing talk to each other directly.

Upgrade a plan → permissions update.
Cancel a subscription → access changes.
Add a team member → roles apply automatically.

No fragile cron jobs. No inconsistent states.

Stop Building Undifferentiated Infrastructure

Users don’t care how clever your login system is.

They care that:

Everything else is overhead.

Simple Login removes that overhead so you can double down on what matters: intelligence.
